I'm trying to boot a Banana Pi M2U that I know is not supported, but I cannot make it even start booting with a SD Card.
Let me explain.
If I use the MFR Debian, image I flash the card and can boot. Another thing is the botched job the image is, that even no init is well done and at the end, the official Debian build ends failing and locking the board or entering in an eternal reboot with some kernel panics in between.
Then I tried Armbian. I downloaded an unsupported image for my board flash it (with balenaEtcher, as recommended) but the board does not boot. A normal boot means a red led, blue and green on. In this case only red one.
What I think is happening is I'm generating a wrong image, but I follow the steps in the documentation, that is un-zip2 the file, run Balena, flash the card and ready to go. As said, with original Banana Pi Debian image and same SD Card, (SanDisk Ultra 32GB) it boots. I've even installed a virtual Ubuunty and generated an image from sources, as described in documentation. Same problem with the generated image.
Once the card has been flashed, my iMAC says "unrecognized disk" for Armbian image, but original Banana image shows a mounted FAT partition called "boot_sd". That is why I think I'm mistaking something when flashing the Armbian image.
I've tried a Centos image from an original PI and at least it starts booting. It does nothing but at least the blue and green led flashes for a time. But with a Armbian it is completely dead.
Any idea?
Thanks.
