TMS320F28335: tms320f28335 flash memory error

Berat,

Please take a look at the example in C2000 Ware here: C:\ti\c2000\C2000Ware_4_03_00_00\device_support\f2833x\examples\flash_f28335.  This has code programmed to flash and copied then ran from RAM.  Please look at both the .cmd file as well as the main code for the key lines that handle the load/run aspect.

Based on what you are mentioning I am wondering if you are in the ILLEGAL ISR, due to the memcopy function not being called before you jump to code that is meant to be in RAM.

If you are seeing a different ISR looping, please let me know.

Best,

Matthew

Thank you for your help, but it enters different isr loops, I don't understand whether my flash memory is not enough or I need to make a setting, but I used msp432 and I did not encounter such an error in about the same line of code. also in my main file memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (Uint32)&RamfuncsLoadSize);
InitFlash(); I already include these lines

I believe we have a list of items to check for when switching between RAM to FLASH.

We will share the bullet list with you shortly

Berat,

Let's take a look at this post for the steps to modify a program to run from flash:

I would also look at the example I mentioned in general, there is also a watchdog on the C2000 that if not serviced or disabled will trigger an ISR.

Best,

Matthew
