Hello l4hackers,
I'm trying to execute Fiasco.OC along with the hello module using qemu and the vexpress machine model. For both A9 and A15 cpus the system hangs at "Starting kernel fiasco". It seems that something (the UART driver?) prevents the system to log the kernel boot to the screen.
I compiled the image using 'make qemu' in L4RE, and the vm is executed with the argument -nographic.
Can you confirm this? Do you have any suggestion to solve it?
Here below you can find the log of the A15 boot process:
