Part Number: TMS320C6746
Other Parts Discussed in Thread: OMAP-L138, OMAPL138
Hi
I am using the c6746 DSP on our board and I try to download the application to the FLASH.
before having our board I was using the LCDK 6748 evaluation board and i managed to download the software to flash using the serial flash loader.
I tried to use the serial flash loader to burn our new board without succeed. even if running the erase option i get the message:
waiting for SFT on the OMAP-L138...
I believe the problem is because in the new board we use uart 0 instead of uart 2 as in the LCDK board.
To solve this I tried to compile the serial flash loader according to the following instructions.
processors.wiki.ti.com/.../Rebuilding_the_Flash_and_Boot_Utils_Package
I had problem to get the arm compiler. the link is for mentor graphic site and its seems that the ARM compiler is not free. I tried to download the free version (but it is for ARM broadcom CPU)
the compilation fails with the error:
make[1]: Entering directory '/home/ilan_r/tmp1/OMAP-L138_FlashAndBootUtils_2_40/OMAP-L138/GNU'
make[2]: Entering directory '/home/ilan_r/tmp1/OMAP-L138_FlashAndBootUtils_2_40/OMAP-L138/GNU/sft'

Do I need the arm compiler if I am using the C6746 DSP?
Next I tried to use the NAND WRITER by importing the ccs3 project to CCS5/CCS7 and compile it but I get many error of type:
"G:/omap138_flash_writer/OMAP-L138_FlashAndBootUtils_2_40/OMAP-L138/CCS/NANDWriter/NANDWriter_DSP/../../../../OMAP-L138/Common/include/device.h", line 84: error #20: identifier "BUS_16BIT" is undefined

Do you have any explanation on failing to compile the serial flash (in cygwin) and the NAND WRITER in CCS
Best Regards
