Unable to use the Freescale M5329EVB target server

Question

Hi everybody,
I have created a new target on Labview embedded which is based on the Freescale M5329EVB example. The target is a powerpc from Xilinx and it runs a linux on it.
What I want to do is to use the "target server" from the Freescale example. I copied all LEP_plugin VIs of this target example and modified them to work with my target.
According to the porting guide, the target server needs a TCP connection, Telnet server and a TFTP client. I implement all of this on my embedded linux and test them. I can connect through telnet and get files through tftp from my linux host.
When I click on the "Download" command, the target starts, connects to the target through telnet and then tries to connect with TFTP. The problem is with the last one, it puts me a message "Awaiting target connection on port 69 ..." but it never connects.
I tried to look to the target server VI's but its quite difficult to understand. The problem seems to be located in EMB_Utility_TFTPD_Listen.vi at the UDP_Read function.
Also, when I netstat my windows, the tftp service is started, so port 69 seems to be opened. Netstat on my target tells me that my windows host is connected to it. The windows firewall is also disactivated.
If anyone has an idea on what's going wrong ...,
Thanks for your help,
François

Answer 1

Hi, sorry for being long to answer.
I have two problems, one for the target server and the other for the debug mode.
In release mode, the executable downloads well and the execution is
good. The error "failed to execute program" comes from
"TargetServer_GetFileSize.vi". The "Match Pattern" box doesn't give the
right information (please see CheckFileSize.JPG). The problem seems to
come from the "file size regex" wire.
Then, if I skip the "checkfilesize" step, the program tries to connect
to the target, but it gives an other error : "Target not found". I set
breakpoints in the "nitargetStartTCPDebug.vi". The ip address seems
good (it's 10.0.0.213 converted in decimal) (please see
TargetNotFound.JPG and Debug.JPG). I wonder if there's a "HOST_IP" to
set in the compile argument or something else.
The other problem is when I try to compile a program in debug mode and instrumented debugging. It gives many errors :
