TMS320F280049C-Q1: TI Boot Code

Hi TI Team,

Recently I wrote a custom bootloader (CAN_kernel_image) which can update the application image through CAN. Custom BL is located at FLAH BANK 0, sector 0 (0x80000) and application at FLASH BANK 1 , sector 0 (0x90000). It is working perfectly fine as expected.

 I also tried to use Boot ROM code instead of custom CAN kernel image, to update the application image. However, it is not updating and as the lauchpad board is not connected through debugger, I am clueless to find the issue. I have set the boot mode pins to boot from CAN (i.e. GPIO24 to 1 and GPIO32 to 0) and using CANA (J14) to send application firmware (eg. Blinky.txt) with 100 kbps speed.  I am using modified

      C:\ti\c2000\C2000Ware_5_01_00_00\utilities\flash_programmers\dcan_flash_programmer\dcan_flash_programmer.exe

to send only application image through PEAK CAN device.

Thanks and best regards

Jens
