Error in loading IBL on EEPROM at EVM C6678 in big endian mode

Hello all,

I'm trying to run NAND over I2C and its working fine in little endian mode. But i want to run same thing in big endian and DSP got stuck after loading the file C:\ti\mcsdk_2_01_02_05\tools\boot_loader\ibl\src\make\bin\i2crom_0x51_c6678_be.bin file into EEPROM. After loading the file When i change the boot mode from Noboot to I2C mode DEVSTAT: 0x0000080A, i believe it must show DEVSTAT: 0x0000082A.

pls help me guys to resolve this issue...

thanks in advance.

rgds,

Gourav

    Hi Gourav,
    1. Please ensure to select the Big endian mode selected on boot mode switches. (SW3,1)
    processors.wiki.ti.com/.../TMDXEVM6678L_EVM_Hardware_Setup

    2. Please re-build the eeprom writer utility in big endian mode.

    3. Upon step 2 completion, use the eeprom writer to load the i2crom_0x51_c6678_be.bin.

    Thank you.

    hi Rajasekaran,

    Thanks for your attention on my query... i have done in the same way only. But it didnt work for me.

    But when i enabled  "swap" option during loading into memory it worked. i guess " i2crom_0x51_c6678_be.bin" file needs swapping option but dont know why ???

    can you pls answer this if you have come across ever ???

    another thing its regarding NAND write, im able to write data into NAND flash in little endian but getting below error with big endian....

    NAND write failed (maximum retries reached)

    can you run my files in your EVM and let me know the output?

     Bin file and nand writer .out file is attached 

    bin.rar

    thanks,

    Hi Rajasekaran,

    Waiting for your reply...
    do u have any working code for NAND flash in big endian????
