TMS320F28027: flash kernel code

Howard Zou

Part Number: TMS320F28027

Hi,

if I want to load code to a locked device, I should modify the cmd file in f28027_flash_kernel project to make it loaded and run in unsecured RAM, right?

But it seems impossible because the total unsecured RAM is just 0x800, which is too small for the whole project.

That is correct. I have aided another customer on the E2E forum to get this working with one of the Piccolo devices. I suggest looking for that thread for some more help.

1) If you have an option of using a ROM flash API library, then use that. 2) Turn on optimizations for the kernel to decrease the program size. 3) see if there is code in the kernel which you do not need and can be removed.
