Hi all,
first of all I would like to thank anyone is contributing, I had an in depth look on this thread and I was able to bring to life my mecool KM9 device.
Hereunder a short summary that will save some headache for mates ;)
My box came with Android 9 and there were no possibilities to enable multi-boot, in order to start playing with it I decided to roll back Android to 8.1; after this step I was just able to boot from external devices, even if it looks that I can't access the box while running on android, probably due to miss behaving BT interface (hanged on remote pairing)
Flashed the image from Balbe150 repo (Linux aml 5.2.1-aml-g12 #5.91 SMP PREEMPT Fri Aug 2 15:24:33 MSK 2019 aarch64 GNU/Linux). Using the dtb file meson-g12a-sei510.dtb I was able to start working on my KM9 having a working ethernet interface.
Currently I'm looking on how to enable BT and WiFi interface, that looks based on AP6255 IC.
Is there someone that is working on this topic too ?
