Hi all, I'm trying to run jailhouse on LX2160ardb (NXP board). To do that, 1. I wrote a cell file for my root cell. 2. I built a Linux 6.1 and a jailhouse (branch lf-6.1.36_2.1.0 from nxp mirror) with yocto. 3. I loaded the jailhouse driver as a kernel module.
But when I try to "enable" jailhouse I get this error : root@lx2160ardb-rev2:~# insmod jailhouse.ko root@lx2160ardb-rev2:~# root@lx2160ardb-rev2:~# root@lx2160ardb-rev2:~# root@lx2160ardb-rev2:~# cat /sys/module/jailhouse/sections/.text 0xffffc45e1113e000 root@lx2160ardb-rev2:~# jailhouse enable lx2160a-rdb.cell Initializing Jailhouse hypervisor v0.12 (369-g6a87b739) on CPU 0 Code location: 0x0000ffffc0200800 Page pool usage after early setup: mem 151/993, remap 0/131072 Initializing processors: CPU 0...
