Logical Channel problem

Hi, everybody in the forum, I'm a beginner in these fields.
While I'm using JCOP debugger simulating JCOP41v22, I found that Logical Channel 1,2,3 is opened by default In Java Card specs I found that only channel 0 must be open by default. Is there any rule that these 3 channels must be opened or closed on card reset, or is it depend on card manufacture?

Hi,
   check thsi link, u can get an idea[http://help.sap.com/saphelp_nw70/helpdata/en/60/183d78163011d2953c0000e8353423/content.htm]

  • Logic Channel Strip Instruments no longer open after Logic 8 upgrade

    I upgraded Logic 8.0 to 8.0.1 and now none of the preset Logic Channel strip instruments will open. I can open all of the instruments on their own no problem. But if I select something from one of their saved presets or an instrument that I've saved, it does nothing, just hangs. There's no beach ball or logic not responding. When you do force quit, it quits logic and then upon a restart of the system, the system just freezes too. This is really frustrating because I've save a lot of my own instruments and can't get to them now. This happen in a previous session and a new session started from scratch with the upgrade. I can access all of my saved audio channel strips. Has anyone encountered this? One more bit of frustration and impediment to my work flow. Thanks, Jeff.

    I've also trouble with that Channel Strips. I've saved and closed a Song with some Mastering-Plugs in the Output 1-2 ( also Stereo Sum ) and after I reloaded that song, there wasn't no Plug anymore. So all my work was gone and I am also very frustrated.
    The next big Problem is working with folders. I've in most of my songs folder of MIDI and Singers and when I am working with this songs on Logic 8, I got many failure in the view of waveforms and regions.
    Sometimes regions doesn't play anymore when I switched between folders in the song. That nervs me up the whole time ...
    Maybe someone can help or can tell me that's why we get ProKit 4.5

  • Logical Channels and Opening An Application

    Hello,
    Upon sending an APDU to a Java Card (a GEM card) to open a channel, it works fine. But when I try to select an application on that new logical channel which is in the secured state, it always gives back an error, but I can select that same application from the basic channel. Do I need to do something else besides simply opening the new logical channel to let it be able to select applications in the secured state?
    Thanks,
    Mizax

    Hello,
    Thanks for your response.
    Yes I'm sure the card supports multiple logical channels, I've checked the historical bytes, and am able to open the number of logical channels the historical bytes say I should.
    I can select other applications on the new logical channel and send commands to them, that works fine. When selecting a secured application, it fails with error code. In particular, I'm trying to select the card manage application, and that fails. Although this shouldn't be necessary, I make sure the basic channel doesn't have the card manager selected also:
    Log:
    Warm Reset Card
    Open Logical Channel 1
    Command: 00 70 00 01
    Response: 90 00
    Select some other App on the Basic Channel:
    Command: 00 A4 04 00 0F A0 00 00 00 18 50 21 00 00 00 00 00 57 49 42
    Response: 90 00
    Select card manager on Channel 1:
    Command: 01 A4 04 00 07 A0 00 00 00 18 43 4D
    Response: 6E 00
    To sum up: Open a new logical channel, select some other app on the basic channel, try to select the card manager on the new logical channel, it fails. If I then reselect the card manager on the basic channel, it works fine. I can select other non-secured apps on the new logical channel, and that works fine too. In any of the cases I mention, I ensure that only one channel is trying to select an app, so that I'm not worrying about the issue of whether an app is multi-selectable.
    I've been wrestling and googling this for hours with no luck. Any help would be greatly appreciated.
    Thanks,
    Mizax

  • Logical channels and secureChannel.resetSecurity();

    Hi,
    1- an external entity A selects an applet APP on logical channel 0 and establishes a secure channel.
    2- another external entiry B selects the same applet on channel 1 without establishing a secure channel.
    3- B exchanges a few commands and responses with the APP.
    4- The execution of the commands in (3) leads to calling secureChannel.resetSecurity() within APP.
    5- secureChannel.resetSecurity() returns the error code 6985 which means conditions of use not satisfied.
    It looks like the secure channel that was established when the APP was selected through the logical channel 0, cannot be reset while the APP is selected on a different logical channel.
    Has anyone faced this situation before? Any ideas how to reset the secure channel under the described circumstances?
    Thanks in advance,
    Hugo

    Hi,
    Logical channel 0 is the basic channel. Have you tried having all host applications on a logical channel other than 0?
    As a rule, we only ever used GP secure channel to secure card issuance/updates or to secure updating the main transport key on the card (the private key had to be encrypted). These actions only ever had one channel to the card open. All other communication was done through a secure channel that was handled by the applet (AES based) that did not rely on the card platform keys so this wasn't an issue in our case.
    Cheers,

  • Access a java card via two logical channels

    Dear all;
    I was wondering if someone managed to do following setup(because it doesn't work for me):
    I have an android phone with a sd-card slot in which I've inserted a java card. I can open a logical channel from my android phone to the java card. Since the java card also suports T=CL, I'm also able to open a logical channel from a pc to the java card via a contactless interface (with a reader that is connected to the pc). But what seams to be impossible is opening the two logical channels simultaniously. So I can't open simultaniously a logical channel from the android phone to the java card and a logical channel via the contactless interface.
    Did anyone have succes with this setup? (I made the applet multiselectable)
    greets,
    JT

    If you are trying to connect to the card over both the NFC controller (card emulation) and the device interface from Android at the same time you will probably have a race condition. On the phones I have used, you can only have one active at time.

  • Supplementary logical channels and R-MAC on JCOP cards

    Hi,
    please, do current models of JCOP cards support supplementary logical channels ? I have found on forums infos saying both yes and no.
    So maybe in earlier years, there was no support, now there is some.
    I have found this post, which may clarify it a little bit:
    All JCOP products have by default only the basic logical channel enabled. The reason is that it shall be GP compliant, and GP spec says that the CardManager must be multiple selectable if multiple logical channels are supported. The CM in JCOP is not multi selectable. If you don't care about GP compliancy (at least on this issue), you can set up to 4 logical channels during pre-perso (JCRE_MODE, two lowest bits).
    However I don't know how to set the JCRE_MODE flags and what they are. I couldn't find any info on them.
    Where are they located and described ? Which APDU command should I use to set them, and with which parameters ?
    And a short second question - are there any JCOP cards, which support R-MAC, when communicating with the card manager ?
    Thanks a lot,
    Peter

In order to do that, you need unfused cards and the corresponding transport key from NXP.
    And a short second question - are there any JCOP cards, which support R-MAC, when communicating with the card manager ?No, JCOP does not support RMAC. Tell me a good reason why it should. I cannot think of any GP commands which would be worth protecting the response.

  • DC In Board or Logic Board problem?

    I have a 12" iBook G4 that's about 2 years old. It's been having intermittent problems reading the charger for awhile now and would flash charging and then not charging over and over again before it would begin to charge up again. This weekend it decided to stop reading the charger completely. The battery works fine in another computer and another battery works fine in it -- it just won't charge again once it loses it's juice.
    It also will not work with just the power adapter plugged in with no battery. The little light comes on, but doesn't seem to pump power into the computer. And it's not an issue with the charger as it charges our other iBook just fine.
    I've read conflicting info elsewhere about what it actually could be so I'm hoping someone could shed some light. Does it sound like just a DC In Board problem? Or a bigger Logic Board problem? Any help would be great... thanks!

    From what I have read on this forum, people have managed to get the DC In Board replaced for a little over US $100. This would be at an Apple authorized repair shop rather than by Apple itself. This is much less than the cost of a new MacBook. I don't know what might be available in your area, but it would be worth asking at a repair shop.
    Good luck!

  • Question about Logic Channel EQ

    When i use Logic Channel EQ to cut low frequencies of say, a kickdrum (in this particular case up to 200hz), the level meter on the channel increases quite a bit. I thought cutting frequencies is supposed to reduce the volume? Also there arent any other plug ins on the channel. Is this normal?

    At it's default setting the low cut on the channel eq has quite a bit of filter resonance at the cutoff point. This resonant boost is what you are hearing. If you lower the Q all the way this resonance will be gone and you will get only the cut you are looking for. If you use the graphic analyzer be sure to set it to maximum resolution as it is quite misleading otherwise.

  • IBook G4 (Jun 2005 model) Logic Board Problem (No Display and HDD noise)

    Hello All
    I have been using my iBook G4 (1.2 GHz) with no problems since I purchased it in June 05. But over the past 2 days, I have been noticing this weird incident of "no display" when booted and I was hearing a loud fan noise at times and I can hear my HDD spinning etc. When I tried to restart pressing CTRL+OPTION and POWER after shutting it down, it booted up but reverted my PMU to a date in 2001 (resetting all my email, music etc). But when I tried shutting it down again and restarted normally, I heard the bootup chime but no display. Again, I could hear the fan and the HDD spinning.
    I took my laptop to the Apple Store here in Boca, FL today and was told that its a logic board problem.
    I know there was a Logic Board Repair Initiative from Apple for the G3's and early G4's. Does anyone know such a thing for the fairly recent iBook G4's??.
    Any help is immensely appreciated.
    Thanks

    How do I verify that my issue is a logic board issue. Recently, computer froze. Tried a hard reboot but no luck. It either shows a blank blue screen or I'll get the grey screen and apple with the start-up spinner but it'll stop spinning.
    That's it. I'm able to browse the contents of the iBook's harddrive when I connect it to my Ti Powerbook via Target Disk mode. I even lauched Disk Utility from the powerbook and verified the iBook's drive and it found no problems.
    Could it be the same logic board issues that you guys are having? How do I verify this? Is it worth paying to repair an 800mhz G4 iBook (applecare expired April '06)?
    I've heard about kernal panic issues with the macbooks so I'm apprehensive about getting one of those right now too. Getting frustrated. Actually considered copping an inexpensive PC laptop... ugghhh.

  • How can I differentiate logic board problem from display problem?

    I have been given an iBook G3 900MHz (one of the models known to have logic board issues.) When I boot it up, I get the Apple chime, the hard drive spins, and the caps lock and num lock lights light up. Sometimes the display comes on, sometimes it does not. When it does, it flickers and goes off and on. I don't get lines or pixels or anything that I have seen described as being indicative of logic board failure. As far as I can tell, the computer works fine otherwise.
    So, how can I be sure the problem is logic board-related and not an issue with the inverter board or the display cable?
    I was also wondering, how much trouble - if any - is Apple giving people about replacing logic boards on certain models of iBook? This one should be eligible, as its serial number falls in the right range and it was bought in Oct. '03, which was within the past three years.
    Thanks!

    there was a period when the display showed colored lines and pixels
    Classic logic board symptoms.
    The iBook freezes a lot
    Mine did, too, with the logic board problem.
    my gut tells me the problem is logic board-related.
    My gut tells me your gut is probably right.
    My question about repair coverage is this: According to Apple's support site, where I entered the serial number, this computer's "estimated purchase date" was October 3, 2003. But the owner no longer has any actual proof of purchase; no receipt, no packing slip, nothing. Is that needed to have Apple replace the logic board?
    No. As I said, I bought mine, used, on eBay. I called in when I recognized the logic board symptoms (I had been working these boards for over a year at that point), they sent a box. It went out on Wednesday. They got it, fixed it, and shipped it back to me on Thursday, and it was back in my hands on Friday. (Practice makes perfect, I guess.)
    Also, does Apple make their determination of age from when the computer was purchased or when it was built?
    Purchase date only.
    Or does that decision depend on if a person can produce a receipt or not?
    Nope. The only paperwork I sent in with mine was the slip Apple sent in the box to indicate what all I was sending them (adapter, battery, extra RAM). What good would an eBay seller's receipt have done?
    I probably have to go to my local service center (in NY that's a place called Tekserve, which is a great place to get a computer fixed, but the wait to be seen averages over an hour!)
    Don't mess around with Tekserve. Call Apple at the number listed on the FAQ page:
    http://www.apple.com/support/ibook/faq/
    Thanks again for your input. I appreciate it.

  • What's mean the Logic channel?

    Hello !!!
    Now I studying the Java Card and ISO7816...
    but I have a probrem....
    I can't understand the logical channel....
    Does logical channel is the path between CAD and JavaCard ?
    um...sorry for my enlish is poor.....

    It's a logical path between CARD and Javacard, as the name indicates. One of the main purpose of logical channel is to select multiple applets in the card. Normally, whenever we select an applet, the previously selected applet gets de-selected and the CLEAR-ON-DESELECT variables of that apples gets defaulted to zero. There may be some scenario where we need to have both the applets selected. Hence, select the first applet in logical channel 0 (which happens by default) and select the second applet in logical channel 1.

  • Continual logic board problems?

    I just had my third logic board replaced (on my ibook G3 dual usb) this week. It goes out every 13-14 months, like clock work. 2 (including the most recent) out of the 3 times apple has replaced it without fuss or charge. When I received the computer this last time, it booted up fine all of my data and programs were there, except the clock was set to 1969. I had backed everything up on an external hard drive, so I decided to do a clean install of tiger. Tiger installed and booted then I shut it down for the night. This a.m. the computer would not turn on. I tried removing the battery, leaving the battery in, unplugging from the power supply, standing on my head etc. nothing, no apple tone, no light, although the keyboard light is on. Question, what happened? I have not tried resetting the PMU but I am not sure that it will work b/c I cannot even get my computer to turn on....Any thoughts before I send it back to the depot.
    also, about the logic board replacement program....is the 3 year time frame a moving window? for example, i bought my ibook in 9-02 but my last logic board was replaced 2-06 is the 3 year time point at 9-05 or 2-09?
    any thoughts are greatly appreciated.

    Your logic borard problem isn't the screen one then? I ask as I have exactly this machine (same RAM too!) and it has developed what sounds like an identical problem. It had its video fault logic board replaced 2 years ago but has been perfect since. Been used daily without a hitch. Then it just shut down without warning.
    Now, if you leave it a while (hrs) it boots. You can then run it for a while, typically 10-20 mins (long enough to drop a back up of all the data over a wireless network which all worked fine). The it just suddently and without warning goes to instant death. And will not power up again. Pressing pwoer key or trying the PMU reset produces no response at all. Battery is ahcrged and charging system works when it is running fine.
    This suggests a logic board problem but not the video one the free warranty covers. But you are saying yours has had this shut down problem repeatedly?
    It has the feeling of being a risk to invest in logic board replacement.

  • Logic Board Problem?

    Hey Everyone:
    I'm still a fairly new Apple user, coming from a world of DIY computer problems. Problem is, this nice compact ibook of mine prevents me from being able to do much on my own. I'm trying to solicit some advice as to what I can do about my current hardware issues.
    About 5 months after having my ibook I noticed white spots on my screen. I knew it would be repaired by Apple, but being the cheap SOB that I am I decided to put it off until the end of my 1 year warranty. I figured I could get everything fixed then, and avoid paying for the extended warranty. Well, I followed through with my plan, but I've noticed some new problems. I'm not too happy about this, but at least I realized these problems in time to extend the warranty.
    The Problems:
    -The first night I got it back, the computer completely froze! Everything working fine, and BAM! The screen looked fine but the entire system was locked up. Fortunately, this only happened twice that night, and I haven't seen it again.
    -Also that first night, the computer would not come out of sleep. It sounded like the hard drive would start spinning, and the flashing light would turn off, but the screen was completely blank. I would be forced to hard reboot, and then things worked better. This led me to a reinstall, but the problem still comes back every so often.
    -One day, I logged in to find that my clock had been reset to 12:00 and somewhere around 1960(?). I set the clock to the appropriate time, and have since realized this could be a PMU issue. I just reset the PMU a few minutes ago, and I'm keeping my fingers crossed this could solve the problems.
    -A couple of weeks ago, the computer would give the dreaded 3 beeps at startup. This seems to imply that OS X can't find the memory bus, but again this seemed to disappear as well.
    I'm looking for some help here. I'm afraid that the Genius bar will just ignore me, because I still can't find a way to reproduce my problems on a regular basis. Yet, the instability is driving me nutty, and I rely on my laptop to get almost all of my work done. Overall, I'm not very pleased with Apple's hardware work. Instead of replacing the entire screen casing, they only replaced the screen itself. That seems like a lot of work with a lot of potential to mess things up on my computer. What's with that farce of a bill that Apple used to convince me to renew my warranty saying that the screen cost $400? No way a screen costs that much, maybe the entire unit. Also, I lift up my keyboard and notice the Technician lost one of the screws. What kind of professional work is that, I ask you?
    Does anybody have any advice on how I can get help with these problems? I just want to get through these rough times while minimizing my inconveniences, and avoiding the potential loss of any data. I am making regular backups, I just don't like the idea that my laptop can die on me at any given time without any warning.
    Thanks!!!

    maciscool,
    That's a good guess, but maybe I wasn't clear enough. The only hardware changes are what Apple did when they replaced the screen. If the RAM is faulty, then it is something they damaged, because everything worked fine before I handed my ibook over to the Genius Bar. I ran memtest, and the Apple Diagnostics CD a few times, and I don't get any errors.
    I'm more curious as to how people knew they had Logic Board Problems, and how did they prove this to Apple. As I see it, a problem such as this would either be disastrous or unpredictabe, that latter being much harder to prove to the retailer.
