Other Parts Discussed in Thread: CONTROLSUITE

I am using F28335 experiment kit.

I write program to blink LED, Put it in RAM – working fine

I put that in flash – working fine

I included SCI input to turn LED off, Put on RAM – working fine

I put that on flash – Not working fine. It is not asking for any input.

Please help.

Variables in Flash cannot be written to via a CPU write. This may be the issue. I suggest looking at some Flash Linker command files in controlSUITE.

Ashish, which cmd file are you using for the Flash configuration. Use the one available in controlSuite from the latest version.

Ashish,

Are you able to execute from Flash successfully?

Thanks and regards,
