Hello. It’s my first post. I have a M2Berry with Debian 11 and OMV6 working really good. I wanted to upgrade to an M2Ultra… but it’s been a nightmare:
- Every Armbian is not booting. Red light just blink every 5 seconds. I’ve tried up to 10 images from 21 to 23
- Ubuntu server falls in boot loop. The red light change to green. I download from wiki.banana-pi: (2020-04-19-ubuntu-16.04-server-bpi-m2u-sd-emmc)
- Ubuntu desktop doesn’t show the display but at least the led change from red to blue in a loop of 2 seconds
- Debian 9 boot until login from the same wiki page. But no ethernet light is showed and no ethernet device is recognized
I don’t know if it’s related but only sd images that have FAT partition for the kernel is changing the red colour to blue.
I’ve tried to disable mmc using a dtbo file following this steps: Banana Pi M2 Ultra boot freezing trying to scan the EMMC - Allwinner sunxi - Armbian Community Forums But not look.
I’m really desperate. Anybody have any clue of what is happening?.. hardware fail? I’m using a PSU of 3A
