AM335x IDK Nand Flashing

Other Parts Discussed in Thread: SYSCONFIG, SYSBIOS

Hello TI,

I am looking for a working "nand-flash-writer_AM335x" example for the IDK board. The source code which is available with the am335x_sysbios_ind_sdk_1.0.0.5 did not work for me. The example hungs when it is accessing the address 0x50000010 (=> GPMC_Write(GPMC_SYSCONFIG, 0, cfg->SysConfig) ).

One issue is the usage of the strcmp function: 

if (strcmp(board_name, EEPROM_BB_BOARD_SIGNATURE))
            return BASE_BOARD;

Actually strcmp returns zero to indicate, both strings are equal, which means "false" for the "if" command. But even fixing this issue does not fix the GPMC_Write problem.

Thanks in advance.

Regards VS

    Hello TI,

    the board detection (i2c_daughter_card_detection()) returns two different results. Sometimes I get this:

    sometimes this:

    What is the correct value for the EEPROM 50 or 51?  I am wondering if the BB board signature is correct?

    #define EEPROM_BB_BOARD_SIGNATURE   "A33155BB"

    I appreciate any help.

    Regards
