Need help on secure binding process boot from NAND

HI Titus:

I do the binding process boot from NAND based on nand_c674x_c6748_lcdkc6748 project, I could not find the following functions, could you point where I can find ?

Hi Mike,

_EMIFAClkConfig ./secure_boot.obj

_EMIFANANDEdmaInit ./secure_boot.obj

_EMIFANANDXferSetup ./secure_boot.obj

_EMIFANANDXferStatusGet ./secure_boot.obj

The log seems to be the "EMIFAClkConfig" was defined no where.

Where did you get "EMIFAClkConfig" declaration ?
I presume that you are trying to initialize the NAND in secureboot.c.
So you can take the code from NAND writer for NAND initialization.

OMAP-L138_FlashAndBootUtils_2_40/OMAP-L138/CCS/NANDWriter/src/nandwriter.c

void main( void )
{
int status;

// Init memory alloc pointer
UTIL_setCurrMemPtr(0);

// System init
if (DEVICE_init() != E_PASS)
{
exit(1);
}

< Do rest of the secure stuff here >

}

Q1) Have you written any test code into NAND flash ?

If so, then after added the NAND init code, try to do "NAND_readPage" function to read your test code headers information (unencrypted)

Use Ref code for "NAND_readPage"

mcsdk_1_01_00_02/host-tools/OMAP-L138_FlashAndBootUtils_2.40/Common/drivers/src/nand.c

Please note that I have appended the last FAQ for NAND secure boot in the following TI wiki.

http://processors.wiki.ti.com/index.php/Basic_Secure_Boot_for_OMAP-L138_C6748#How_to_do_secure_boot_from_NAND_flash.3F

Please let me know if you have any issues.

Hi Titus:

I have written the test code to NAND flash.

I build it based on nand_c674x_c6748_lcdkC6748 project in starterware, how can I get the following functions? are they in a LIb, I can not find where they are.

Could you please send me your project through private chat and not here.

Hi Stalin:
could you please re-open the private chat, the one you offered a while ago is closed.

I used the following command to get secureboot.ais when port the security collateral update with nand read and write, compiler shows no error.
SecureHexAIS_OMAP-L138.exe -ini secureboot.ini -otype binary -o secureboot.ais secureboot.out.
then run the "secureboot.ais" through "GenericSecureUartHost", it show boot completed. the code does not run. what am i missing. I would like to get your advice.

Mike
