Dear all,
I have compiled l4android, l4 and fiasco for arm architecture and now I am attempting to run elf image in qemu.However, I see only a black screen in qemu. There is any io messages. What could be the reason? My qemu version is 1.7.1. The images that I have after making elfimages are: bootstrap.elf bootstap_L4LinuxARM bootstap_L4LinuxARM.elf
The used command for running image:
$qemu-system-arm -M realview-pbx-a9 -m 2048 -kernel bootstrap_L4LinuxARM.elf -serial stdio
Thanks in advance,
Sincerely, Cem Akpolat

Can you show us the output on the serial line? This could give a hint where it is failing. Also you can make io more verbose by providing multiple '-v' as an argument to io.

Btw, the standard ARM L4Linux example does not use a graphical output. Did you modify the example accordingly?

According to the qemu documentation the PBX-A9 target provides a maximum of 1024M of RAM. However, Fiasco and L4Re can only use 512M if I remember correctly.
