Oled screen on quad sata hat, no display

#1

Hello, I have ordered and installed this: https://wiki.radxa.com/Dual_Quad_SATA_HAT

I have setup the script and dependencies. I2C is enabled. rockpi-sata service is running

I can show a video of the fan spinning at the top, just the oled screen isn’t displaying any information.

I am running raspbian on a rabpberry pi 4b

I have run: apt update/upgrade/full-upgrade

I have python3.9 as a default on the system, and I saw some error when running the instal script, so I’ve installed python3.8 and configured that as the default, but the problem remains!

Thanks

Check out i2cdetect command output to see if it see i2c device address correctly

#3

Check whether the i2c device exists, via

sudo i2cdetect -y 1

#4

Output of command: sudo i2cdetect -y 1
root@rpi4-nas:~# sudo i2cdetect -y 1

Hey all,

this issue is resolved

I was previously running my OS off of an SD card, and I’ve now booted from a fresh install of debian 11 on USB drive

After going through the install steps again, the screen now works!

So for people in the future, try booting from USB/doing a fresh OS install - and see if that tells you anything

Thanks everyone
