Data Verification error while loading program

Arye Lerner
Expert 1130 points

Hello,

I am at the start of bring up of a custom board based on OMAPL137. I used OMAPL137EVM Starter kit before that.

I managed to set the JTAGJet to work with CCS Studio and recognize the new board.

The problem ocuurs when I try to load the program file (*.out) via File->Load Program utility. It generates an error:

Data Verification failed at address 0xC36205A0.

Please verify target memory and memory map.

When I try to load different project that also worked on EVM, it generates same error with different address.

The SDRAM memory size and type are the same as in EVM. I use CCS 3.3.

 I suspect that this is have to do with external RAM being damaged or problem in its interface . If it is - how can I check the entire memory? Is there a tool in CCS and/or JTAG program for that?

What else can cause this error?

 

Regards

Arye Lerner

    Arye,

    The Board Support Library for the OMAPL137 EVM includes test code that performs a basic test of the external memory that you might be able to reuse for your board.  It's located at:

         {InstallDir}\evmomapl137_v1\dsp\tests\sdram

    In addition to Tommy's suggestion, the data verification error simply means that whatever CCS tried to write to that memory was different than what it read back. This could be caused by any number of things such as invalid EMIF register settings, a lack of physical memory at that address, improper signaling or potentially a bad memory chip as you suggested. It is difficult to narrow these things down without going through them one by one, but a simple memory test could help show the scope of the problem.

    Thank You!

    It was JTAG configuration problem, But it was good to find out about memory test.

     

    Thank You

    Tommy,

     I have a same problem as Arye .I get this error when I try to load the program file (client .out) via File->Load Program utility onto the EVMOMAP-L137:

    "error : file loader

    data verification failed at address 0xc00dd000.

    please verify target memory and memory map."

    but some other "*.out" file load on this EVM without any problem.

    as you mentioned , I run "sdram.out " from "evmomapl137_v1\dsp\tests\sdram " on my EVMOMAPL137 and get this message :   FAIL... error code 191... quitting    Whiles it runs on another EVMOMAPL137 without error .

    How i can solve this problem ?

    Thanks in advance,

    Zahra Mazaheri.
