F28235 moving from Ram to Flash

robert bond

I'm looking at SPA95L8L which uses TCF file and an older complier/liker. I'm currently using CCS7.4, *.cfg file, TIv18.1.3LTS. It runs fine in ram but now I need to run out of flash. Is there a later example I can refer to?

Hi,

You can take a look at "Running an Application from Internal Flash Memory on the TMS320F28xxx DSP" application report: http://www.ti.com/lit/spra958

I look at that and it refer to everything with TCF file where some of the config is not in the CFG file config. like call User init function before main. I did notice that in CFG there is a boot area that has a enable boot from flash but I get error when I enable it.

Hi,

You will have to update the linker command file to allocate the code to Flash.

Pls refer this thread
