Hello, I have faced an issue in using serial ports when I need to skip a couple of ports in the CLI.
For example the ARM machine netduinoplus2 supports up to 7 UARTS. Following case works (the first UART is used to send data in the firmware): qemu-system-arm -machine netduinoplus2 -nographic -serial mon:stdio -kernel path-to-fw/firmware.elf But this one doesn't (the third UART is used to send data in the firmware): qemu-system-arm -machine netduinoplus2 -nographic -serial none -serial none -serial mon:stdio -kernel path-to-fw/firmware.elf The patch fixes the issue. Best regards, Bohdan
