One has to freeze kernel and u-boot upgrades because generation of new uInitr does disable linux kernel hdmi. Disabling of hdmi in u-boot has to be implemented into armbian nanopi-m4v2 u-boot.

Did try few resent images as of beginning of feb 21 for nanopi-m4v2 and compiled my own using the armbian build and tried to move u-boot support for hdmi - bud did have to plug the hdmi cable after starting kernel .... This pilter75 image does bypass u-boot hdmi and therefore allows the kernel control of hdmi https://users.armbian.com/piter75/Armbian_21.05.0-trunk_Nanopim4v2_buster_current_5.10.18_minimal-stability-fix.img.xz There is one problem - USB 3 do flicker. It is not possible to restore with rsync. Might be because I did install full firmware o

Is it the new u-boot hdmi bug (conflict) u-boot hdmi - kernel hdmi https://github.com/armbian/build/pull/2016/files ?

Vondering if this has something to do with AppArmor or the hardware partitions grep APPARMOR /boot/config-* CONFIG_SECURITY_APPARMOR=y CONFIG_SECURITY_APPARMOR_HASH=y CONFIG_SECURITY_APPARMOR_HASH_DEFAULT=y # CONFIG_SECURITY_APPARMOR_DEBUG is not set CONFIG_DEFAULT_SECURITY_APPARMOR=y This is from successful Armbian 21.02.1 Focal with Linux 5.10.12-rockch

Now it boots Armbian 21.02.1 Focal with Linux 5.10.12-rockchip64 successfully every time from emmc. To those of consern about /dev/mmcblk2boot0 and /dev/mmcblk2boot1 and RPMB partitiones. This is http://trac.gateworks.com/wiki/MMC some info about hardware partitions on some emmc. "man mmc-utils" and "sudo dpkg -L mtd-utils" and man mmc UART

This is strange - "and totally easy going ". After starting the board with bullseye 4.4.213 SD card and then right away starting with fresh 5.4.43-rockchip64 SD card then it all of a sudden did boot up. Then armbian-config - sytem - boot and flash to emmc - but 5.4.43 does not boot now from emmc- same UART messages as from the SD card. Edit: Did boot from 4.4.213 sd card, shut down, remove sd card, reset button, stop u-boot - run bootcmd_mmc1, and 5.4.43 did boot up from emmc. apt update; apt upgrde and reboot now and reboots so it is working.

The image is Armbian_20.05.1_Firefly-rk3399_focal_curent_5.4.43 - the with rk3399-firefly.dtb - and I did work - but not now ? Armbian bullseye 4.4.213 and rk3399-firefly.dtb does always work - and is just fine image for this board. Just experimenting with newer kernel. This is where it halts - votages and RTL UART
