I am currently trying to make a non-root Linux-cell work on the Jetson
TX2-board. I have created a new jetson-tx2-linux-demo.c file and have made
a inmate-jetson-tx2.dts file according to the other ARM examples given.
When i try to start the cell with
sudo jailhouse cell linux
> ~/linux-jailhouse-jetson/configs/arm64/jetson-tx2-linux-demo.cell
> /boot/Image --dtb
> ~/linux-jailhouse-jetson/configs/arm64/dts/inmate-jetson-tx2.dtb -i
> /boot/initrd
i get the following error:
Traceback (most recent call last):
File "/usr/local/libexec/jailhouse/jailhouse-cell-linux", line 846, in

arch.setup(args, config)

reg += struct.pack(reg_format, region.virt_start, region.size)

My jetson-tx2-demo-linux.c looks like this:

So my question is, whrere to search for the error, since the defined memory
regions are in bounds of the value given by the error message.
Thanks for any advice
