imx8qxpc0mek-jailhouse

[sai9]

Hi,

i am working on enabling the jailhouse hypervisor on imx8qxpc0mek board, i have successfully enabled it.

After running the following command:

jailhouse cell linux /usr/share/jailhouse/cells/imx8qxp-linux-demo.cell  /run/media/mmcblk1p1/Image -d /run/media/mmcblk1p1/imx8qxp-mek-inmate.dtb -c "clk_ignore_unused console=ttyLP1,115200 earlycon=ec_imx8q,0x5a070010,115200 root=/dev/mmcblk1p1 rootwait rw"

The problem is when i open another port(/dev/ttyUSB1) i am not able to the jailhouse logs. i have also checked all other available ports.

Can anyone suggest me here.

Thanks,

Hello,

I think there are serveral issues:

1. console=ttymxc0,115200 in your bootargs, but your inmate boot log show ttymxc1. Note, root cell and inmate not share uart console, inmate just use earlycon for print log on root cell in the beginning.

2. From your boot log, there is no mmcblk2p2, so you not burn eMMC with an valid image.

Regards

In my case, root cell console=ttyLP0 (0x5a060000,115200)
and inmate cell console=ttyLP1 (0x5a070000,115200)

Below is the dmesg logs.

I have modified the command to set the earlycon and console as below. Still I am unable to see the logs on earlycon logs and inmate cell logs.

I am not sure where I am going wrong. Any quick response would be helpful.
