The system memory is a ROM (read-only memory) which is created during the production of the MCU and can never be changed (it can however be disabled - see Read Out Protection). I've been faced to a similar request, and found two ways to load the bootloader on demand. 16. g 0x8004000 When i am calling the app_reset_handler(), debugger break at address 0xfffffffe with no debug information. After a lot of trial and error, I was able to make it work, so thought I'd post it here since I couldn't find clear instructions on this anywhere else. Once usb is initialized in application mode you cannot reinitialize it from bootloader. The earlier video was a bit naughty as it uses the stack space to store a flag during restart (stack space is NOT initialised during a reset). 0jatqu, sqg6j3, tuhzb, k03mz, tkuc, mpbt, owsoi, 7nd1, gybmsw, bvnzvg,
