Are the USART*_TX pins configured as push-pull outputs when in system memory mode from the beginning or only after selection of the USART interface (0x7F received)?
Hi,AN2606 (STM32 microcontroller system memory boot mode) states e.g. for the STM32F301, that in system memory boot mode both USART_TX pins (USART1_TX & USART2_TX) are used as outputs. Is the TX pins really configured as outputs as soon as the system...
