Hello,I used to generate code from STM32CubeMX then edit, compile and flash to board with Keil µVision (default config). Recently, I followed bootloader tutorial that uses STM32CubeIDE and I must admit it's nice but for exact same source code, the ge...

Bug found in search_string_in_Mainbuf the second inner_loop can prevent the outer_loop from exiting so need to add the exit condition like this:uint8_t search_string_in_Mainbuf(char *string, volatile uint16_t *index, uint16_t index_end) // Search str...

Hello, Thank you for answering my question.1) "You're doing too much processing" current code is working 99.99% of time so I'm not sure this is the root cause here. Can you tell what is the limit you consider OK?2) I understand your idea but I don't ...
