CCS/TMS320F28035: Flash image clone by Uniflash for later programming

Part Number: TMS320F28035
Other Parts Discussed in Thread: UNIFLASH

Tool/software: Code Composer Studio

Dear Champs,

I am asking this for our customer.

Originally, they have several steps for programming from 3rd party and factory.

For example, their factory program a 3rd-party bootloader by JTAG first and then use that bootloader for later firmware update, padding flash, and then use CSM.

Now, they want to simplify the manufacturing process by one-step JTAG programming.

Can they just take a finished (programmed) F28035, unlock it, read back all the flash content and store it into a .out file on PC by Uniflash memory export. Then use that .out file for later flash programming and mass production?

That is, they want to clone the flash image from a programmed F28035 for later production.

    Yes this should be possible. They can export unlocked memory to a COFF (*.out) file format and then flash the same file on another device. Note that the *.out file generated is a bit different than one from a CCS build (no debug symbols, but different format) but it is a COFF format that can be flashed.

    Thanks
