BootLoader & SWD

Posted on June 14, 2018 at 07:18

Hello, dear colleagues, can anyone come across this situation. The STM32F405 processor is perfectly programmed with BootLoader,

but I need to make changes in the program and debug from SWD.

As I do not fight, but on SWD I can not program FLash, from Keil,

when I program it I get a message: the timeout has elapsed when I access Flash.

No keys to protect Flash-memory in BootLoader did not install.
