Hi everyone,
I’m using TMS320C6424 EVM kit, and I’m trying to boot from NAND flash, NAND boot mode requires an AIS image, according to the application Report SPRAAK5B, Perl genAIS utility is used to generate an AIS image script as following
genAIS.pl -cfg evm.cfg -otype ascii -i OUTput.out -o MyperlNAND.ais -bootmode nand
, the issue that the image generated doesn’t work properly, even in case of EMIFA ROM Fast Boot With AIS (NOR Flash),
genAIS.pl -cfg evm.cfg -otype ascii -i OUTput.out -o MyperlNOR.ais -bootmode emifa
I also tried to boot from nand using a customized external secondary bootloader (from the EEPROM) and it worked properly. But in case of AIS NAND boot mode an invalid AIS command was received.
I tried another tool to generate an AIS image (C642x_FlashAndBootUtils_trunk),it works properly for NOR, but this tool is dedicated to the NOR flash solely.
The generated NOR AIS image by both of these tools (Perl genAIS utility and C642x_FlashAndBootUtils) for the same .out file differs significantly!!! Works for C642x_FlashAndBootUtils but not for the Perl one!!
So, what did I miss ?!!
Regards…
