MSPM0L1306: CCS program load

Part Number: MSPM0L1306
Other Parts Discussed in Thread: UNIFLASH

I am using the boot_application example form the below wiki to run the MCU boot on the MSPM0L1306 launch pad evaluation kit with a 64KB internal flash. The compiled boot_application_LP_MSPM0L1306_nortos_ticlang.out is 232KB and I am able to debug the application using the CCS theia fine. However the memory viewer has a maximum size of 0x4600. Please find the map file.

MEMORY CONFIGURATION

         name            origin    length      used     unused   attr    fill
---------------------- -------- --------- -------- -------- ---- --------
FLASH                 00000000   0000fff8 00004600 0000b9f8 R X
SRAM                  20000000   00001000 00000c70 00000390 RW X

Question:

How does CCS Theia able to intake 232kB and flash the relevant sections only to the MCUBOOT slot?

Eventually I need to program the boot_application at the factory to the MCUBOOT slot.

Once I click debug application I see that ccs theia is loading program from 0 to 17920 (0x4600) bytes at 0x0

My goal is to flash the boot_application_LP_MSPM0L1306_nortos_ticlang.out to a new eval kit using some tool stripping unnecessary symbols similar to what the CCS theia program loader is doing.

Question:

Can I convert the tiarmhex utility to convert to .hex file and use uniflash to program the flash memory on a new Launchpad?

Uniflash (the utility which flashes the device) can accept an executable ELF file as input.

Probably. Sorry, but I lack the expertise to say for sure. I know it is not a strict requirement that you convert the ELF file to hex. I'll notify the relevant experts about this thread.

Thanks and regards,

Updating for the benefit of others. The .out file generated has all the symbols hence we used the tiarmhex utility to strip the symbols ( --dwarf-off) and created a bin/txt/hex file. With this we could successfully flashing the bin file using uniflash.
