JTAG to axi Master: Can't write to the memory

Hello,
I am trying to make a very simple design in order to write and read to the memory using JTAG to axi master IP core. I did my design based on the following quick take video:
https://www.youtube.com/watch?v=btJ5Q7psf9M
After downloading the bitstream and trying to work with the tcl, everything goes well until when I want to use the write command:
run_hw_axi [get_hw_axi_txns $wt]
I will receive the following error :
ERROR: [Xicom 50-38] xicom: AXI TRANSACTION FAILED
INFO: [Labtoolstcl 44-481] WRITE DATA is: 44444444_33333333_22222222_11111111
ERROR: [Common 17-39] 'run_hw_axi' failed due to earlier errors.
What is wrong? 
Here is more detail about my design:
1. The only top module is the vhdl wrapper for the block design which has been generated by the ip integerator
2. The clock is running at 100MHz.
3. the reset is grounded to 0, i.e. I don't have external reset signal
4. I have tried different clock frequency while connecting it to the JTAG, didn't help
Thanks,
Aryan

I removed the clocking wizard ip and connected the clock directly to the design block. works perfectly now

  • Can I write in the layout  in any Key figure something else then number ?

    Hi
    (sem - bps)
    Can I write in the layout  in any Key figure something else then number ?
    Let say I want to right in the key figure number with CHAR (the letters a-z)
    Can I do so ?
    Can a key figure  has char other then number ?

    no i can't , because the user want to assign a characteristic ,for example (the layout) :
    0employye  0amount 0project
    P1211111   1000   #
    after the user will assign :
    0employye  0amount 0project
    P1211111   1000   ea-5819
    can the user assign 0project ?
    the current solution i mange to build was :
    a variable with 2 characteristic 0employee & 0project
    and with user exit i move the values to Variable
    ,and in the fox i use substr to split the variable ,
    the code is :

  • My iPod touch needs to be restored. however, all of my movies/apps/songs/photos are not backed up on my computer because the shop on my computer does not work. can i still get the memory on my iPod touch 32gb back?

    my iPod touch needs to be restored. however, all of my movies/apps/songs/photos are not backed up on my computer because the shop on my computer does not work. can i still get the memory on my iPod touch 32gb back?

    If you weren't able to sync the purchases to a computer previously and now your iPod needs to be restored so you can't sync it now, then you may be out of luck and will need to purchase your content again. Officially Apple does not allow redownloads of purchased items other than iPhone/iPod touch applications and iBooks. The official statement of their policy can be found here, among other places.
    You can try contacting iTunes Store Customer Service (select the "Music Purchases" or "Video Purchases" category, as appropriate, then "Lost or Missing Items". You'll find either an "Express Lane" button - just follow the instructions to get to the contact form - or an "Email Us" button) ") and explaining what happened. Reportedly in some cases Apple has allowed redownloading on a one-time basis. But don't count on it. 
    Good luck.

  • How can i write to the Step.Result.ReportText of a Sequence callback?

    i need to write to the Step.Result.ReportText and step.Result.Status of a sequence callback using a statement but it jus won't work...how can i do this?....

    I am not sure what you are asking but will give it a shot.
    Only a step has Step.Result.ReportText and Step.Result.Status properties. Therefore you cannot set these properties for a sequence callback. For certain callbacks that are called by a sequence call step, you can set Step.Result.ReportText and Step.Result.Status of the Sequence Call step that called the callback. To do this you can set Runstate.Caller.Step.Result.ReportText and Runstate.Caller.Step.Result.Status within the callback.
    If this does not help you then you must provide information as to which callback you are using and for what step you want to set the Step.Result.ReportText and Step.Result.Status properties

  • The light on my apple tv is blinking furiously.  i've held down the menu button, plugged and unplugged it, and just tried restoring it via micro usb.  but the restore downloads then says it can't finish because it can't write to the disc.  lost lost

    how do i get the light on my apple tv to stop blinking?  have tried all the recommended methods, including holding down "menu" on remote, plugging and unplugging etc.  when i try to restore via itunes it downloads then when it's done says it can't write to disc.

    Hi lostinmedford,
    Welcome to the Apple Support Communities!
    I understand that the light is quickly flashing on your Apple TV and you are unable to restore it. According to the attached article, you are working through the correct steps by trying to reset and restore the Apple TV. In this situation, if the restore did not resolve the issue, it may be necessary to have the Apple TV evaluated for service by using the link in the attached article. 
    Apple TV: About the status light - Apple Support
    Flashes quickly
    Having issues. Try restarting or waking your Apple TV. If your Apple TV does not start up properly, you might need to reset the Apple TV or restore it to factory settings. See Apple TV (2nd and 3rd generation): Restoring your Apple TV. If this does not resolve the issue, refer to the Service FAQ for additional assistance.
    Best regards,

  • How can I zero out the memory on my macbook air?

    I have an 11 inch mid 2011 macbook air and cannot figure out how to erase the memory so that none of the data is recoverable. I booted from the recovery HD but when I went to the erase section of the menu, the security options button and the zero out empty space option were both greyed out. How can I clean off my Mac?

    You can't, and don't need to, zero an SSD in Disk Utility. Once you've erased it the data is unrecoverable.

  • How come I can't free up the memory by deleting the photos?

    i have been trying to free up memory on my iPhone and deleted a lot of my photos, however it doesn't seem to work. it says i have only 231 photos left in camera roll (i don't have any other album) but when it's plugged to the computer with iTunes, it says photos taking up 12.8GB of storage... how can 231 photos be taking up so much storage?
    how can i free up the storage?

    Normal photos don't take up that much space the only way I could see photos being that large in size is if the photos have files within them. This is usually done when you iPhone has been hacked or when you use 3rd party software to put files within files. These are the only ways I could see this being done my advice to you is to restore your iPhone start over with a new one you will have more memory.
    Two questions
    where did you get your iPhone?
    was it used or new?

  • How can I write to the parallel port using LabVIEW 6.0.2

    I have tried updating the labview.ini file and also using the parallel.llb available on the site. When I execute the program it gives me error 37 saying,"device not found". I am running this code on windows 98. I tried to use VISA write,serial port write (using port 10) but nothing seems to work. I also tried to develop a sample code using inPort and outPort, but no success, it is not able to read the data back from the parallel port, even if it seems (????i don't know any way to cross-check it though????) to write.
    Does anybody know the problem here?
    THanks.
    Pari.

    Thanks Brian.
    Well here is the next problem. I got a VI (attatched) off ni.com and it works fine on a windows98 platform. But quits working on NT.
    I can write perfectly (which i checked by hooking an LED display unit at the other end of the parallel port cable). I observed that the LEDs respond to the toggling of individual bits (data bits). But the error occures at the "out port.vi", when I try to run it on a NT machine (where I actually wanna use it). Are you aware of any changes to be made in order to run a VI on NT that works on 98?
    Thanks again.
    Pari.

  • How can you write over the other JTablecells while putting in information

    like windows excel when you write in a cell and you get to the border everything covers the other cells... when you press enter the string is in the textfield. But with the default settings of JTable or is it the DefaultTableEditor or the DefaultTableRenderer i don't know, when you write someting in a cell and get to the border everything is pushed to the left...i don't like that...
    Can someone help me here?
    thanks in advance

    Hello Tim,
    thanks for your response. Meanwhile I found out, that in fact things work fine. I "tested" the outputfile in opening it with the Notepad editor. That was not the proper way to do it. Making a file dump, I saw that everything was alright. So if one wants to work on such a file with the editor, one should use the Writer classes.

  • LabVIEW DSC 2011 / OPC Client IO Server / Can I write to the OPC Server using OPC Groups?

    Hi
    I am using LabVIEW DSC module as a OPC client. My Shared Variables are binded to automation system OPC Server via "OPC Client IO Server".
    On the OPC Server side it seems that the every write commands comes like one item at time, not like grouped.
    Now I have tested this with the NI OPC Server as server and KepServer and LabVIEW DSC IO Server as OPC Clients.
    When I use the NI OPC Server : OPC Diagnostics there are different events messages when the update request comes from KepServer or LabVIEW DSC.
    There are log files on attachements for both write events.
    Attachments:
    Data from the KepServer.txt ‏6 KB
    Data from the LabVIEW DSC OPC Client.txt ‏18 KB

    Hello Pentsi,
    I have received confirmation (from the PSE in the US) that DSC doesn't support group writes
    There however work-arounds that might provide a solution:
    - The first solution I had in mind was like this. Update the 50 OPC items as fast as possible.
    Then use a 51st item as synchronization OPC item to check/indicate if new data has arrived/has been set/is available.
    So LabVIEW sets 50 OPC values as fast as possible. The 51st value becomes goes from false to true when the first 50 values are written.
    When this (51st) value is true on the OPC server you can read out the first 50 values (from the non-LabVIEW side). When you've read out these values, then you can set the 51st value back to false (from the non-LabVIEW side).
    In the meanwhile at the LabVIEW side you wait until the 51st value goes back from true to false.
    When it becomes false, then you write again those 50 values and afterwards set the 51st synchronization value from false to true.
    And this keeps on going...
    Note: Keep in mind that you only have to monitor one event at the side of the Automation System OPC Server in this case (the 51st) and based on an event occuring over there you can just do a group read of the 50 others. Also keep in mind that the maximum rate (6500 updates per second) from inside LabVIEW with the DSC Module OPC client I/O server was also mentioned in this document (http://digital.ni.com/public.nsf/allkb/63C043359F1​E12538625726E005BCD0C?OpenDocument).
    Could this be a possible solution for your problem?
    If you're using one of the OPC servers in this list (http://zone.ni.com/devzone/cda/tut/p/id/6417#toc19), then you can also use NI OPC Servers to update tags instead, which supports a faster update rate.

  • [Urgent]How can I write to physical memory by using LabVIEW 8.2??

    Hi everybody,
    I am dealing with a project related to micro-EDM. We feed the gap voltage back to a NI DAQ card (not quite sure about the series number, might not be important to this problem), and we want to use this voltage to determine the command position of the motor, which is controlled by a Delta Tau PMAC motion controller. Now the problem is, the NI DAQ card and Delta Tau PMAC controller cannot communicate directly with each other. Therefore, we want the LabVIEW to write the value of voltage to a certain physical memory address, and then let the PMAC controller read that address. Is this feasible by using LabVIEW and NI-DAQ card? Which block or library in LabVIEW shall I use to achieve that? Or is there any alternative way to do it? Thanks a million!
    I have to get this done by the end of this week....if you know how to do it, please let me know. I really appreciate it! You are my lifesavor!

    I just got the iPhone 5s then tried to down load app then I was order the and all my information in there beside I put wrong email that why when they submit it will wrong address I couldn't recive .that why I was re done my account again . Then I done it ... But when I go back to down load the app .that come up the wrong I was sign include my wrong email ?
    So what can I do now ????

    Creating a new Apple ID is a VERY BAD IDEA. If you can't remember your password or your Apple Id, CALL APPLE and they will help you retrieve it.
    Once you create an Apple ID and password, IT IS VITALLY IMPORTANT THAT YOU REMEMBER IT! Write it down somewhere. Forgetting this information can cause you to lose all the music, movies, books and applications that you downloaded under that account, AND can even cause your iDevices to be bricked.
