[Xen-users] Issue while booting Xen

[Janani Krishnan <jananikrishnan20@xxxxxxxxx>]

Hello,

I am facing an issue while booting Xen on pineA64 plus. I am using UBoot bootloader. UBoot boots perfectly and starts Xen. Once Xen starts few lines are printed. The output stops once "(XEN) Command line: sync_console console=dtuart dtuart=/soc@01c00000/serial@01c28000 dom0_mem=128M" is displyed. The Xen output is as follows :

## Flattened Device Tree blob at 58000000
   Booting using the fdt blob at 0x58000000
   reserving fdt memory region: addr=58000000 size=6000
   Loading Device Tree to 44ff6000, end 44ffefff ... OK

Starting kernel ...

The following UBoot commands were used to boot Xen

setenv xen_addr_r 0x42000000
setenv kernel_addr_r 0x52000000
setenv kernel_size 0x1901A00
setenv dtb_addr_r 0x58000000

setenv xen_bootargs 'sync_console console=dtuart dtuart=/soc@01c00000/serial@01c28000 dom0_mem=128M'
setenv dom0_bootargs 'console=hvc0 earlyprintk=xen ignore_loglevel clk_ignore_unused root=/dev/mmcblk0p2 rw'

ext4load mmc 0:2 $kernel_addr_r /boot/Image
ext4load mmc 0:2 $xen_addr_r /boot/xen
ext4load mmc 0:2 $dtb_addr_r /boot/dts/allwinner/sun50i-a64-pine64-plus.dtb

fdt set /chosen/modules/module@0 reg <$kernel_addr_r $kernel_size>
booti $xen_addr_r - $dtb_addr_r

I am unable to figure out what is going on.

Kindly help me out.

Thank you.
