STM32F207: Toggle GPIO During operation flash execution code in RAM

jimmy4399 · ‎2019-06-19

Hi community,

I would like to toggle GPIO when operation flash (Erase and Programming)

I have tried relocation vector table and code in the ram

I have determined vector table and code in the ram，Keil Debug mode show their address in the ram after 0x20000000

The above is what I tried, but they didn't solve the problem.

Please advise. Thank you.

How important is the problem? It would take some time/effort to demonstrate this.

Probably also want to do it in a free-standing system, not in the debugger.
