Hi, I just am getting started in the BPI community but I’m hitting some blockers right out of the gate. I received my BPI R2 (v1.2) with Android preloaded on the emmc.
I’ve tried to boot from 3 different images (ubuntu-mate linked in getting started, armbian, opensuse) and 5 different brands of SD card all with no success. I’ve tried dd, bpi-copy, etcher. Same non-result in every case.
No matter what happens, it always just boots into Android. To dig in I’ve tried to hook up the UART dev interface and connect w/minicom or screen.
I have the UART -> USB cable hooked up, and no matter what I do there, I always get garbage on the interface. I’ve tried changing the speeds, using screen vs minicom, using the uart on the 40 pin connector vs the dedicated uart pinout. Nothing works. On the 40pin I never get any input, but on the dedicate uart “dev” pins I only get serial garbage|690x379
At this point I don’t know what I can do to get past this pre-installed android build and on to arm linux distros.
I’m not sure if I have a hardware failure somewhere or if I’m just missing some critical step. Any direction or ideas is appreciated!!
If its of any help, I purchased the kit from here: https://www.amazon.com/gp/product/B079BQ45RC/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
Thanks in advance! Andrew
