I'm using a OKMX8MQ-C which from imx8, now i can boot the root cell and some simple demp such as gic-demo. But when boot the non-root linux cell, i face some problem.
I only use initramfs to boot non-root linux. Furthermore, my initramfs only contains a helloworld and a console device. [I cannot use busybox to build initramfs because my toolchain does not allow me to compile it]. My ramfs directory is as follows：[image: 截屏2023-11-25 14.49.49.png] Then my startup command is as follows: *cd /home/root/imx_jailhouse * *insmod driver/jailhouse.ko * *export PATH=/home/root/imx_jailhouse/tools:$PATH * *jailhouse enable configs/arm64/imx8mq-veth.cell * *jailhouse cell linux configs/arm64/imx8mq-linux-demo.cell \ * * ~/Image2 -d \ * * ~/imx8mq-evk-inmate.dtb -i \ * * ~/rootfs.cpio.gz \ * * -c "clk_ignore_unused console=ttymxc0,30860000,115200 earlycon=ec_imx6q,0x30860000,115200 root=/dev/ram ramdisk_size=10000000 rdinit=/hello rootwait rw " * Eventually, I got the following output： root@imx8mqevk:~/imx_jailhouse# jailhouse cell linux configs/arm64/imx8mq-linux-demo.cell \ _unused console=ttymxc0,30860000,115200 earlycon=ec_imx6q,0x30860000,115200 root=/dev/ram ramdisk_size=10000000 rdinit=/hello rootwait rw " > ~/Image2 -d \ > ~/imx8mq-evk-inmate.dtb -i \ > ~/rootfs.cpio.gz \ > -c "clk_ignore_unused console=ttymxc0,30860000,115200 earlycon=ec_imx6q,0x30860000,115200 root=/dev/ram ramdisk_size=10000000 rdinit=/hello rootwait rw " [ 567.018158] Ready to search binary handler...
