Hi,
I have some problems getting the serial console to work under qemu with ARM/realview-eb. I see the output from L4Linux but it does not get any input and also pressing escape does not enter jdb. I have tried qemu 1.0 and 0.12.5. I call it with
qemu-system-arm -M realview-eb -nographic -m 256 -kernel .../l4re/obj/l4/arm-rv/images/bootstrap_L4Linux_ARM.elf
Are there any options one need to pass with "-append"? "-append -serial_esc" does not make any difference. Any other ideas?
L4 version is from l4re-snapshot-2011081207.tar.xz
Output from qemu is below.
Cheers, Stefan

Hi Stefan, when I start Qemu I add the command line option "-serial stdio". Maybe that helps. And my 'modules.list' entry contains 'kernel fiasco - -serial_esc'.
Cheers, Julian

Hi Julian,
On Tuesday 07 February 2012 14:50:39 Julian Vetter wrote:
when I start Qemu I add the command line option "-serial stdio". Maybe that helps. And my 'modules.list' entry contains 'kernel fiasco -serial_esc'.
"-nographic" implies "-serial stdio". But the problem was actually the missing "kernel fiasco -serial_esc" line in modules.list. I somehow thought that the command line options would have to be provided externally, like they are with grub, but they are included in the built elf file. Thanks in any case.
Cheers, Stefan
