Dear Jan
In fact, my hardware platform is banana PI M1+, I do not find "Banana Pi M1+" in the
" images.list ".
Is there a jailhouse-images supported for "Banana Pi M1+"?
Not explicitly. We support the classic Orange Pi Zero, but that is also
A20-based. Maybe you can use that image on the M1+ as well, only tuning some
boot parameters and using different Jailhouse configs (all available ones are
being installed) in the end. I don't have such board in reach to cross-check,
unfortunately.
In general, ARMv7-based setups with Jailhouse need to be considered more as
demonstrations than as production platforms. Those SOCs typically lack SMMUs
that you need for full isolation, and most activities on ARM-side now go into v8
designs.

Thanks you very much~

Dear colleagues,
In the “Setup on Banana Pi ARM board” part, it mentioned that “*since
v2015.10, you need to disable CONFIG_VIDEO in the U-Boot config*, or U-Boot
will configure the framebuffer at the end of the physical RAM where Jailhouse
is located.”
My question is that how to disable CONFIG_VIDEO in the U-Boot config?**
Via "make menuconfig" during the manual u-boot build - which the description is
not covering in details. If you do not want to fiddle with that, I can warmly
recommend jailhouse-images [1] and a board that is supported by it out of the
box.

...and we can also discuss directly if you have further questions.
That said, generic discussions via the mailing list are always very much
appreciated as they strengthen the community. Thanks for taking that route!
