i am running a debian8 amd64 machine and i would like to emulate an:
armhf machine with kernel > 3.8 (docker testing)
i succeed to have a debian7 (3.2 kernel) working fine, but kernel is too old. It seems kernel cannot be updated from that point.
I have tried the same approach with debian8:
netboot install, with a vexpress machine (-M vexpress-a9 -cpu cortex-a9) : does not start at all.
May be because vexpress kernel does not exist in installer for debian8.
I am pretty new to arm, and i don't know what is the meaning/relation between vepxress types of machines and arm different architectures.
my last try with ubuntu trusty armhf port, was a bit better, as machine starts to boot but freeze when asking the first question at installation time:
qemu-system-arm -m 1024M -sd armdisk.img -M vexpress-a9 -cpu cortex-a9 -kernel ./netboot/vmlinuz -initrd ./netboot/initrd.gz -append "root=/dev/ram" -no-reboot
Any hint would be greatly appreciated :D
