Re: Error regarding filesystem in Dom0 in lager board

Ok thanks for the reply, I have applied the dts file. My observations are:

Adding hypervisor node has no effect on booting. For me even without
hypervisor node it is getting booted up to mounting filesystem. After that
point the system hangs as given in the log.

Adding psci node results in breakdown of Xen. Xen gets crashed without
booting linux DOM0.

regards,
George
