You can actually use any one of them to send serial data to your PC’s terminal using a USB-TTL converter. Leave other settings as they are. Use the qemu-system-aarch64 executable to simulate a 64-bit Arm machine. -t qemu_stm32 It can run the examples in stm32_p103 STM32 Nucleo F103RB UART Data Transmit Example. In the file stm32f7xx_hal_uart. Somehow you don't Plug'n'Play with those, at least on self made custom PCBs. Then, the xterm windows will show the output and also will also accept and redirect input. pm yc sh sn ea wg om hz av nk
