TMS320F28069: Bootloader Development

Vishal,

Yes, you can develop custom bootloader which uses SCI-B. You can use SCI_Boot.c file available in controlSuite as your reference.

Path: <controlSUITE>\libs\utilities\boot_rom\2806x\2806x_boot_rom_v1_1\source

Thank you Manoj.

I have created a separate workspace and tried to build the code given in below path.
Path: <controlSUITE>\libs\utilities\boot_rom\2806x\2806x_boot_rom_v1_1\source

1] After first build compiler were giving few error related to boot.h,
"../source/I2C_Boot.c", line 63: fatal error: cannot open source file "Boot.h"

To resolve this issue, I included following paths in include options,
"${workspace_loc:/${ProjName}/F2806x_headers/include}"
"${workspace_loc:/${ProjName}/include}"


2] After second build I was getting following error,
"../lnk/TMS320x2806x_boot_rom_lnk.cmd", line 56: error: cannot find file
"Flash2806x_API_V100.lib"

To resolve this issue, I copied "Flash2806x_API_V100.lib" file from below path "C:\ti\controlSUITE\libs\utilities\flash_api\2806x\v100a\lib" into the project work space location

Now I am not getting error, but following warnings are coming.

[Query]
1] Could you please let me know about how to resolve these warnings?

2] When I tried to download the program into target hardware, I got following error.
C28xx: Loader: One or more sections of your program falls into a memory region that is not writable. These regions will not actually be written to the target. Check your linker configuration and/or memory map.
C28xx: File Loader: Verification failed: Values at address 0x3FF72C@Program do not match Please verify target memory and memory map.
C28xx: GEL: File: C:\CPT Source Code\2806x_boot_rom\Release\TMS320x2806x_boot_rom.out: a data verification error occurred, file load failed.

Requesting you to answer above queries.

Vishal,

1) You can ignore this warning. This warning just tells that the library file was build using older code gen tools.

2) Address 0x3FF72C belong to BOOTROM and not flash.

Manoj
