MECOOL KI Pro EMMC Install

[martinlanger90]

I have a MECOOL KI Pro with CoreELEC installed onto EMMC.
Can I boot armbian from you from USB/SD/TF and install it onto EMMC right away?

Thank you.

Is it this one? You can test the firmware of s905d.
If necessary, you can modify the value(meson-gxl-s905d-mecool-ki-pro.dtb) of dtb in /boot/uEnv.txt, which is the same as CoreELEC.

[martinlanger90]

Yes it is that one. But it doesn't boot from USB/TF (microSD Card).
Did the same as for CoreELEC. Stops at Mecool logo. CoreELEC is actually installed to EMMC.
Any advice how to boot armbian? changed uenv.txt to meson-gxl-s905d-mecool-ki-pro.dtb

[martinlanger90]

Okay, installed original Android again. Tried to boot from microSD card. Did not work either. Hangs at mecool logo.

Download the 5.4 kernel firmware and unzip it. Double-click the .img file, open uEnv.txt, and modify the name of the dtb file to meson-gxl-s905d-mecool-ki-pro.dtb. Change it and rewrite it to usb.
First turn on the USB debugging mode of the box in the Android system. Then plug in usb and power to start.

Thank you. Exactly that worked. Tried with 5.10 all the time. Didn't work... 5.4 worked via USB stick

Try to save u-boot-p201.bin as u-boot.ext

chmod +x u-boot.ext

[ophub]

Can the firmware of the 5.4 kernel be booted from usb?

[martinlanger90]

Yes. Now I'm using 5.4 with nothing changed besides the dtb in uEnv.txt and works flawlessly now. Trying to install to internal after configuring wifi

[ophub]

Use 5.10 kernel, Try to save u-boot-p201.bin as u-boot.ext and changed besides the dtb in uEnv.txt

[martinlanger90]

Okay, I'll try that in a second.

[martinlanger90]

Okay, works with 5.10 kernel as well. The key was to use USB Stick and remove CoreELEC from NAND as that changes the boot partition on mmcblk as it seems.
Using USB boot in Android and correct dtb (*ki-pro.dtb) with nothing works as well with 5.10.
Thank you for the great support.

According to my method, the 5.10 kernel can also be used?

u-boot-p201.bin as u-boot.ext
changed the dtb in uEnv.txt as meson-gxl-s905d-mecool-ki-pro.dtb

[martinlanger90]

Download the 5.4 kernel firmware and unzip it. Double-click the .img file, open uEnv.txt, and modify the name of the dtb file to meson-gxl-s905d-mecool-ki-pro.dtb. Change it and rewrite it to usb. First turn on the USB debugging mode of the box in the Android system. Then plug in usb and power to start.

Yes. that did it with 5.10.

[ophub]

Okay, it's okay to use 5.10 instead of 5.15.

I would like to ask you to try again: Is it possible to use u-boot.ext under the 5.4 kernel, so that u-boot.ext and .dtb can use the same one
