Web17 jan. 2015 · With my calculations I was able to find the r1 correctly but after that I fail.For example the r2 come out 0x05 and at the end r0 come out 0x10C how can this be,there is no code here to save the r0 on to the memory why it changes.I guess my dont know what to do with r2 and r4.Anyone has knowlage about ARM help will be really good. WebSTM32F4Discovery Bootloader activation without BOOTx Pins. Posted on December 15, 2014 at 18:46. Hello, is there a possible way to access the Bootloader-Mode after a System-Reset without the use of the BOOT0 and BOOT1 Pins?
