New to the Rock PI S, so bear with me as I am getting up to speed.
Got my Rock Pi S (v1.2) with 512Mb Ram and 1Gb Nand yesterday. Followed the ‘Getting started’ instructions from https://wiki.radxa.com/RockpiS/getting_started. Flashed ubuntu image to an SD card [sandisk extreme 32Gb]and plugged it into the Rock Pi S. Supplied power via the USB-C USB-A cable, connected a USB 232 serial adapter to pin 6,8,10.
And I see the Rk3308 booting up. COOL. It boots up all the way and start several services and prints
‘Welcome to Ubuntu 18.04 LTS!’, but no prompt.
it sits there for a second or two, and then it resets.
then you see the message DDR Version V1.26 … followed by U-boot and it restarts.
This then repeats over and over.
tried different images:
Same story. They all show the same behavior.
What am I missing? is there a watchdog running?
and one point it succeeded yesterday and I was able to log in. But I tried now all morning and it consistantly fails.
ADDON led info:
I see the green led coming on, and shortly after the blue one flashes twice. Then all leds go off.
