Qemu pre-built kernels without serial console?

[Lluís Batlle i Rossell]

Hello,

as I see in the configs for the prebuilt qemu kernels:
CONFIG_SERIAL_8250=m
CONFIG_SERIAL_AMBA_PL011=y
CONFIG_SERIAL_AMBA_PL011_CONSOLE=y
CONFIG_SERIAL_CORE=y
CONFIG_SERIAL_CORE_CONSOLE=y

Does this mean that a serial port like that of qemu (isn't it like a
16550?) doesn't work? I'd like to use "-nographic". I can't manage to
get any output using "-nographic -append console=ttyS0".

Regards,
Lluís.

qemu-system-arm can emulate the pl011.

Try ttyAMA0 instead of ttyS0?

Oh, I didn't know. I thought qemu gave a 8250 or alike.
