imx8qm jailhouse

[Ahelion]

Hi all,

Is there any document showing all the steps to have a demo running on imx8qm mek board with jailhouse?

I was going over this: L5.4.70_2.3.3_LINUX_DOCS

but all I could find is a reference to device trees:

Hypervisor Jailhouse Enables the Jailhouse Hypervisor device trees.
• imx8qxp-mek-root.dtb: DTB for root-cell

I do not know what to do with this info. That is why I need a step by step instruction list.

Br, Mircea

hi @Ahelion

i am planning to use MCIMX8QM-CPU soc  i need to bringup freertos and Android on top on this do we need hypervisor here,

and also Jailhouse is already present in the latest version of android ?

[Ahelion]

Waste of time. Nothing works out of the box on nxp imx8qm, at least not with the software provided by nxp. Android does not run in jailhouse, on imx95 they have a small android demo running in xen. freertos can run on the second core m3 core, you can flash the emmc with android and have it like that running. no hypervisor needed.

@Rita_Wang Xen willl support on latest kernal 6x?

[Rita_Wang]

Hi @Shivu_Guru_24 ,

Sorry for late reply. For the XEN the on latest kernal 6x do not support it.

If customer want to use, they can do porting themself. In our BSP 4.14.98 support it. Customer and refer it:

Embedded Linux for i.MX Applications Processors | NXP Semiconductors

Hope this can do help for you

Wish you have a nice day

Best Regards

[Rita_Wang]

Hi @Shivu_Guru_24 ,

I can tell you right now, it is not supported. I could not get jailhouse or xen to work on imx8qm. Whatever documentation i find is referencing linux4.9, which can not be build anymore.
