ROCK PI 4C+ with Dual/Quad SATA HAT

Hardware and peripherals

Hello,
I come to ask for help, whenever I can get the HAT to work, the Oled works for a few seconds and blocks and the fan even without the HAT installed is always at maximum, not being able to control the speed after install the rocki-penta.service.

Hi,
it seems you installed the wrong software for the quad sata hat. You should use the script here:

I already tried, always install rocki-penta.service, am I doing something wrong?
I think I have permissions issues.

Hello All,

No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 11 (bullseye)
Release: 11
Codename: bullseye

Dual/Quad SATA HAT installed
mraa compiled and installed
and the problem continues: fan always FULL speed and screen non responsive
HDDs detected and running on RAID5

Can someone please explain to me what I’m doing wrong?

Thanks in advance

I tried every os, every release and nothing works on the Rock Pi 4c+. I cannot for the life of my understand why allnetchina state this on their site.

I eventually gave up and sold my Rock Pi4c+ and bought a Raspberry Pi 4 & it worked first time.

Hi,

I tested with both Rock Pi 4C+ and Raspberry pi 4 and seems like rock pi 4c+ does not work with quad sata hat

Hi.
I tried to set up 2 SDDs with ROCK Pi Dual/Quad SATA HAT. every time I set this with this steps, (

it can access the drive after setting it up from another device. but after restart it cannot access or it does not rebooting to the pi os. it gives an error on boot ([DEPEND]
Dependency failed for mnt.mount - mnt.
Timed out waiting for device dev-disk-by\x2duuid-1e32cc21\x2d1af9\x2₫444\x2d969\x2d5abbe2590bed .device - /dev/disk/by-uuid/1e32cc21-1af9-44e1-a969-5abbe2590be

Looking for HELP.
