Hello to all,
I have a Raspberry Pi 4, 4Gb version, and the complete Quad SATA kit.
Yesterday I installed the new Raspberry Pi 4 firmware in order to boot from USB (saw a lot of tutorials in Youtube).
On the procedure, it’s mentioned that we need to reboot the Raspberry several times.
After installing the new firmware and reboot the Raspberry, I noticed that the Top HAT LCD didn’t light up. Also, I noticed that the top fan was not working.
Thinking that something went wrong, I returned to my previous firmware and rebooted once again: no luck; the LCD and the fan didn’t work.
I then reinstalled HAT’s firmware (using the command curl -sL https://rock.sh/get-rockpi-sata | sudo -E bash -) and reboot again but still no fan nor LCD.
I can see that the HDD Leds, on the HAT, are working just fine and I noticed that the rockpi-sata.service was running. I tried to stop the service and start again, but no luck.
So, my question is: how can I debug why the LCD and the FAN are not working?
Please note that everything was working flawlessly and just upon the firmware upgrade I lost the LCD and FAN.
Also, I cannot format and install everything again because I am using my Raspberry as a NAS with a lot of Docker images with lot of services.
