Hi Peng,
Thanks for replying.
Yes, I have tried the following,
export PATH=$PATH:/usr/share/jailhouse/tools
insmod /lib/modules/5.15.32-iot-gate-imx8m-3.2.1+/extra/driver/jailhouse.ko
jailhouse enable /usr/share/jailhouse/cells/imx8mm.cell
jailhouse cell list
jailhouse cell create /usr/share/jailhouse/cells/imx8mm-inmate-demo.cell
jailhouse cell load inmate-demo /usr/share/jailhouse/inmates/gic-demo.bin
jailhouse cell start inmate-demo
jailhouse cell stats inmate-demo
*Which is working without any issues.*
I find the reported issue with linux-demo
looking forward for support on the same.
Thanks and Regards,
Bharathiraja Nallathambi
