[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] Debugging Dom0 on OMAP5
Hi,
I have been trying to get Dom0 running on OMAP5 for a while now.
Right now i can't get even a single print from Dom0.
Based on a recent thread on the list i have tried adding
xen_raw_console_write() in vprintk_emit() but even that doesn't help.
Strangely Xen keyhandlers other than 'd' are not working so i can't even
get Dom0 state dump.
I have tested the zImage boot on the board via bootz command of U-Boot
and that works fine.
Is there any constraint on where the xen-uImage and zImage should be
loaded? Any suggestions on how i could debug this?
So far i get just the following prints from Xen...
U-Boot# bootm $xen_addr_r - $dtb_addr_r
