Hello.
I tried the steps, but my Mecool KIII pro don't run using default conf
extlinux.conf:
label Armbian_community
kernel /Image
initrd /uInitrd
fdtdir /dtb/amlogic/meson-gxm-mecool-kiii-pro.dtb
append root=UUID=3bc7a8b8-73ee-4ade-9030-f3fa965fc27e rootflags=data=writeback console=ttyAML0,115200n8 console=tty0 rw no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0 splash plymouth.ignore-serial-consoles
But I need choose (unofficial)
label Armbian-unofficial
kernel /Image
initrd /uInitrd
fdtdir /dtb/amlogic/meson-gxm-mecool-kiii-pro.dtb
#Insert the correct FDT line for your box's dtb in the extlinux.conf file
#The dtbs for Amlogic s9xx boxes are located in /boot/dtb/amlogic
#For example for a TX3 mini box the FDT line to insert would look like this:
FDT /dtb/amlogic/meson-gxm-mecool-kiii-pro.dtb
append root=UUID=3bc7a8b8-73ee-4ade-9030-f3fa965fc27e rootflags=data=writeback console=ttyAML0,115200n8 console=tty0 rw no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0 splash plymouth.ignore-serial-consoles
Thx
