imx8qm xen boot flow details

[Ahelion]

Hello experts,

I am following this guide: https://www.nxp.com/docs/en/user-guide/IMX_YOCTO_PROJECT_USERS_GUIDE.pdf

to build an image with xen, my target for now is too boot 2 linuxes(same ones 6.1.55) and then one linux and one android.

I have enabled xen, when I do bitbake xen I get the xen image, but one thing is puzzling me: https://community.nxp.com/pwmxy87654/attachments/pwmxy87654/imx-processors/171234/1/IMXVIRTUG_ga.pdf

This document mentions how to setup the sd-card, but it is not exact, it is vague(chapter 3.4 mentions broadly 3 partitions). Can you tell me after my yocto build finishes what to flash in which partition? and if I need to prepare the partitions in some fashion, as the yocto generates just the rootfs part and the u-boot stuff separately.

Br,

no, it does not, do you have an oficial NXP doc? with modern linux inside of it ( 4.19 is a bit old).
I need to know, from power on, where does u-boot look, where does SECO, ATF come into play?
