TMS320F2800137: How to debug boot28.asm file

Hi Joe,

When you say "boot project", do you mean the OTP/DCSM settings? Does the customer have the source files for both projects or just the final .out?

Where does the boot28.asm file come from?

Thank you,

Luke

Let me clarify the boot project, after the code start from 0x80000, customer only do the necessary MCU initialization, and decide whether the firmware should be updated, finally let the code jump to the APP code, that's what I call boot project.

Yes they have all the project source file.

The boot file is from our compiler, direction is ccs1281/ccs/tools/compiler/ti-cgt-c2000_22.6.1.LTS/lib/src/boot28.asm.

Thanks

Hi Charles

I checked the F28002x_lfu_singlebank demo and serial_flash_programmer to understand the single-bank LFU solution. It seems that boot and APP are two separate projects, firstly I load the boot in MCU then I use serial_flash_programmer to load the APP into MCU.  How can I combine the boot project and APP project into one .out or .hex file and program the whole firmware at one time.

Thanks

Joe

Hi Joe,

TMS320F28374S: How to merge two hex file from boot and APP into one hex file to make the production more easier? - C2000︎ microcontrollers - INTERNAL forum - C2000︎ microcontrollers - INTERNAL - TI E2E support forums

Related thread on merging two hex files into one. Also, as mentioned in Section 6.4.1 of CAN Flash Programming of C2000 Microcontrollers, you can combine two .txt files by splicing the addresses, where one image is represented as Image A and the other Image B.

Thanks and regards,

Charles
