Based on 26f52bfde573479960d8696f407d19b9 http://dl.clockworkpi.com/DevTerm_A06_v0.2h.img.bz2

Since uconsole and devterm are using the same main board

Just need to update a new kernel for uconsole LCD screen

Kernel

https://github.com/clockworkpi/uConsole/tree/master/Code/patch/a06/20230630

Combine linux-dtb-current-rockchip64_23.02.0-trunk_arm64.deb and linux-image-current-rockchip64_23.02.0-trunk_arm64.deb to a new deb file

One of the more complicated tasks is merging preinst, postinst, postrm, and prerm files.

cat  linux-image-current-rockchip64/preinst  linux-dtb-current-rockchip64/preinst > preinst

cat  linux-image-current-rockchip64/postinst  linux-dtb-current-rockchip64/postinst > postinst

cat  linux-image-current-rockchip64/postrm > postrm

cat  linux-image-current-rockchip64/prerm > prerm

sudo gparted /dev/loop0 #resize it,fullfill empty space with last partition by mouse drag

Chroot

Chroot into DevTerm_A06_v0.2h.img by

sudo mkdir -p /mnt/p1
sudo losetup --show -f -P DevTerm_A06_v0.2h.img  #assume loop0
sudo mount /dev/loop0p1 /mnt/p1

cd /mnt/p1

sudo mount --bind /sys sys/
sudo mount --bind /proc proc/
sudo mount --bind /dev/pts dev/pts
#sudo mv etc/ld.so.preload etc/ld_so_preload

#remove old configs for screen rotation,since new uconsole a06 kernel did screen rotation 

* nano /boot/armbianEnv.txt ,remove   "fbcon=rotate:1"  
* rm -rf /etc/X11/Xsession.d/90custom_xrandr  
* rm -rf /etc/lightdm/setup.sh  
* rm -rf /etc/lightdm/lightdm.conf.d/13-rotate-dsi.conf  

exit #quit chroot

Clean chroot

do it everytime when you are done with chroot enviroment

cd -
sudo umount /mnt/p1/dev/pts
sudo umount /mnt/p1/dev
sudo umount /mnt/p1/proc
sudo umount /mnt/p1/sys
##clear bash 
sudo rm -rf /mnt/p1/root/.bash_history
sudo umount /mnt/p1
sudo losetup -D /dev/loop0
