I'm facing a problem of getting the STM32F3 Discovery board bootloader to work. AN2606 calls for pattern 2 to be applied so I pulled up the BOOT0 pin. A check with STLink shows the nBOOT1 bit is 1 so upon powering up the board, the application firmware inside the MCU did not run. But when I send 0x7f through USART1, there is no response from the bootloader.
Anybody has any idea what I'm missing?
