FW: Kernel panic error while emulating qemuarm image

[Arjun Padmanabhan]

Hi,

Thanks for the reply.

Update: For default compilation(armv5e) without changing tuning features, I could run qemu(2.7.0) with built image. Issue  of kernel panic happens when I change tuning feature file as I mentioned in trailing mail.

Thanks
Arjun Padmanabhan

Hello,

Could you try out the instructions under :

        https://github.com/openbmc/docs/blob/master/cheatsheet.md

and please use this qemu tree :

        https://github.com/openbmc/qemu

Mainline is missing a few models.

Thanks,

C.
