[Qemu-discuss] Accessing both uart of machine -virt (aarch64)

[Vincent]

Hi !
I'm trying to test a bare metal aarch64 OS using qemu 'virt' machine.
So far I'm only running the EL3 part of the OS.
I am using the following command line to start qemu:

qemu-system-aarch64 -machine virt,secure=on -cpu cortex-a57 \
    -smp 1 -m 4096 -kernel my_kernel.elf -serial stdio

When I access the VIRT_UART device, I can see my prints on the standard
output of my console, but if I access the VIRT_SECURE_UART, I don't see
anything.

Can I redirect both uart to the same output (stdio) ?
Otherwise, how can I interact with both uart ?

Best,
Vincent
