imx8qm-mek Digital Cockpit does sign boot images is necessary for 2 dual OS bootup?

[kengyulin]

I've built the Digital Cockpit image follow by document :

i.MX Linux® User's Guide, Rev. LF5.10.72_2.2.0, 17 December 2021

i.MX Digital Cockpit, Rev. LF5.10.72_2.2.0, 17 December 2021

Does CH4 sign boot images in Digital Cockpit is necessary for 2 OS Yocto boot up at once?

Is there any hint that I can build or combine dual OS boot up with Yocto and Android by Hardware Partitioning?

We are using imx8qm and are intending to use it as both IVI ( in-vehicle infotainment  ) as well as IC ( instrument cluster ) application.

we have gone through following document - 

https://www.nxp.com/docs/en/user-guide/iMX_DIGITAL_COCKPIT_HW_PARTITIONING_8QM.pdf

we wish to use Android as HLOS for both. Is it possible?

Hi @kengyulin 

Not to sign boot image is okay for two OS bootup at once.

Best regards
