Hi Arnd,
> Is this backwards compatible with old firmware?
Sorry, it is not backwards compatible.
Another reason is that it could support opensuse
more smoothly.
I have updated the firmware and uploaded it
into Linaro Hisilicon git tree last month.
We will update the wiki on Linaro soon.
Do you think it is OK?
Thanks!
Best Regards,
Wei
