RTOS/TMS320DM6437: NDK based RTOS project cannot be booted from nand flash in TMS320dm6437

Part Number: TMS320DM6437

Tool/software: TI-RTOS

hi,

i have built small application over NDK which i can run in debug and it is running fine. but when i convert the .out file to TI AIS format(.bin) using ais_utility (Under spraag0e) and then load the file using NANDWriter project of TI into nand flash, it does not boot.

i have converted and loaded my previous projects into nand flash all are booting properly from nand.

the NDK based application project has .out file size of 1209 KB and converted ais format ( .bin) file size is 262 KB. All code memory is assigned to DDR as per .TCF file of NDK.

I have generated .bin file with and without .cfg file. both the generated files fail to boot after flashing into nand.

what can be the problem??

hii,

This problem got solved after properly analyzing .cfg file provided with ais_utility (Under spraag0e) and changing the DDR arguments as per the DDR in our board. Basically when all the sections of our project/code is in DDR, DDR should be initialized before using gel file in Debug and using cgf file in boot.

thank you
