I've tried running realview-eb against L4 kernel built for arm926EJ and it runs smoothly without any glitches :)

I was trying to run L4 for the smp variant (esp cortex a9 to be precise).

As per the qemu documentation

"realview-eb" - doesn't support support cortex a9, the one which i needed was with smp more than 1 (2 or 4)

{ Eg: novino@naveen-linux:~/L4/l4re-core-2011020417/src/l4/mybuild-realview-eb-a9/images$ qemu-system-arm -M realview-eb -cpu cortex-a9 -kernel bootstrap_hello.elf -m 256 -nographic -net nic -net user -smp 4

Number of SMP cpus requested (4), exceeds max cpus supported by machine `realview-eb' (1)

However when i try to run any variant of L4 built for cortex a9 i'm getting stuck at the time of execution.

The three variants i've tried are

1) L4 - Cortex A9, realview-eb, other settings default. Qemu Board - realview-eb

If any working combination is there which has been tested/tried for Cortex A9 please let me know :).

PS: I don't have TI/Nvidia board but if it has been tried to be working on them, i can plan to get one. However wanted qemu to be my first choice, because of the ease of usage of gdb to debug L4.

The board-check passes on the real board. If I remember right it didn't
really work as the real board last time I tried but that's some time
ago. Things might have changed, I should retry.
Anyway, any particular reason you want to use that config? 'realview-eb'
should just work fine.
