[U-Boot] Booting u-boot for versatile in qemu fails

[Thierry Bultel <thierry.bultel@wanadoo.fr>]

Hi,

I am trying to use u-boot configured for uboot_versatileqemu in 
qemu-system-arm.

I only get a black screen a no serial output at all.
I have tested several versions, and taken latest u-boot from 
git://git.denx.de

I have also upgraded qemu to 1.5.0-rc2

My command line is as follows:

qemu-system-arm -M versatilepb -m 128M -kernel u-boot.bin -serial stdio


I have configured u-boot like that:
make CROSS_COMPILE=arm-linux-gnueabihf- versatileqemu_config

My compiler is:
#arm-linux-gnueabihf-gcc --version
arm-linux-gnueabihf-gcc (crosstool-NG linaro-1.13.1-4.7-2012.10-20121022 
- Linaro GCC 2012.10) 4.7.3 20121001 (prerelease)

I also tried the ca9x4_ct_vxp, because I often use vexpress kernels in 
qemu for vexpress-a9, but no better success

Is there a configuration that is known to work ?

Best regards
Thierry
