Data Verification Fails on C6745 L2 RAM

Other Parts Discussed in Thread: OMAP-L137

Hi Champs

A customer of mine is trying to load code to internal RAM of his custom C6745 hardware. He uses a BH 560m emulator. As test app he uses the hello.pjt included in BIOS. When he tries to load the .out file, data verification fails always at the same address in L2 RAM. We tested it on a OMAP-L137 board and it worked. Since the memory maps are the same, we cannot explain this behaviour. Does anybody have an idea what could cause this error?

Thanks,

Niko

    Hi Niko

    Was this problem resolved?

    If not, any additional details on the failures? Does the OMAP-L137 board test done using the same BH 560m emulator setup?

    Note, last time I saw someone encounter a similar sounding issue on a custom board was when the customer had forgotten to hookup the internal RAM power supply/ RVDD power pins ( Pins 67,159 on the PTP package or pins H6,H12 on the ZKB package) appropriately. Can you ensure that this is not the issue with the custom board.

    Regards

    Hi Mukul ,

    I have same problem with EVMOMAP-L137 .

    I want to transmit a pocket of data from my PC to the EVMOMAP-L137 and receive a pocket of data from the EVM via network.

    I am using the NDK 2.0.0 on evmomap-l137 and CCS v3.3 and i have the " evmomapl137_dsp.gel " that was in EVMOMAP-L137s CD.

    I am running the example called "client" in "ndk_2_0_0\packages\ti\ndk\example\network\client ".i compile and build it correctly but when i am going to loading the "clien.out " this error message appears:

    "error: file loader

    data verification failed at address 0xc00dd000.

    please verify target memory and memory map."

    I think that i should change something(s) in "evmboard.tcf " file but don't know what?

    can you help me?

    Regards,

    Zahra Mazaheri .
