Hi Florian,

It would be great if you could help me with it.

Currently, what I am doing is.

 root@arm$ ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make -j4

Then I am using Busybox to build the root filesystem

root@arm$ qemu-system-arm -M vexpress-a9 -dtb
./linux/arch/arm/boot/dts/vexpress-v2p-ca9.dtb -kernel
./linux/arch/arm/boot/zImage -append "root=/dev/mmcblk0
console=ttyAMA0" -sd ./a9rootfs.ext3 --nographic

Which machine I should use for ARMv6 in QEMU. Which dtb file I should
use for ? All these questions I have. If anybody knows please let me
know.


Best,
Shubham Bansal
