TMS320F28069: Write to own Flash at runtime?

Thomas,

The rule here is that you cannot program the flash while code is running from it. 

Now, you can re-program the flash during execution, but the code would need to be running from RAM while the reprogram is occurring. You can copy a small portion of code with API calls from flash to RAM and then jump to it to do the above.  Once the erase/program is complete you can jump back to flash.

We have an example of this in C2000Ware C:\ti\c2000\C2000Ware_4_03_00_00\device_support\f2806x\examples\c28\flash_programming or here is the cloud link if you prefer.
