Cables are all plugged in and Penta SATA Hat is mounted according to Youtube instruction.
No brideges set or pins shorted. All hardware was shiped form Radxa in late November 2021.

Would you like to install a new system using an SD card and test it out? I don’t know what environment is messing with it.

Karl-W · January 21, 2022, 4:34pm

karl@rock-3a:~$ cat /proc/device-tree/mode

Karl-W · January 21, 2022, 4:35pm

Any reccommendation regarding der Version and Linux Brand? Ubuntu or Debian or what and packaging date / Version?
Further Question: What would you reccomend ro use to tranfer the hopfully working SD Image onto the eMMC? DD?
Would you or others recommend a direct transfer or would you make use of an image that then may be transfered via an other machine? Or woul youm after knowing all Parameters and sving tthese to on of the HDDs redo the intstall from the scratch havint to take appart the whole Rock 3a SBC plus the HAT?

setq · January 22, 2022, 1:48am

Sorry, typo. cat /proc/device-tree/model

setq · January 22, 2022, 1:56am

You can test it with the latest Ubuntu. It looks like you tried to install other libmraa earlier, I don’t know if you messed up the environment.

Karl-W · January 22, 2022, 11:35am

Wierd behavior

Karl-W · January 22, 2022, 11:37am

“librmaa” install … did so as instructed… Will give it a Try and come back if needed, after wiping and Disassembly

Rekkid · January 22, 2022, 5:01pm

what i did to run ubuntu from emmc:

download image https://github.com/radxa/debos-radxa/releases/download/main-7f328c0c/rock-3a-ubuntu-focal-server-arm64-20220117-0232-gpt.img.xz
flash it on sd card via Balena Etcher
insert it in rock-3a
put emmc module
assemble penta hat
power it up with penta hat dc
then dd
sudo dd if=/dev/mmcblk0 of=/dev/sda bs=1M status=progress
where mmcblk0 - my sd card, sda - emmc
when it is done, i made resize via parted (to bring back size of emmc)
sudo shutdown and eject sd card

after that i’m booting from emmc

After that u can do apt update and everything else

Karl-W · January 24, 2022, 7:46am

Perfect description THX.
Next question Do you haven any stratey to make the rock 3a boot from /dev/sda or any other SSD or HDD (eg.a seperate boot partition hdd)?

Karl-W · January 24, 2022, 10:37am

Problem :
The eMMC must have same or bigger size than the SD Card.
The correct command line would be :
sudo dd if=/dev/mmcblk1 of=/dev/mmcblk0 bs=1M status=progress.
SDA would be one of the HDDs.

So, there’s no way around a fresh upload the UBUNTU IMG to the eMMC by etcher.

Also the hat’s fan finally seems to be woking, still the HAT’s LCD-Display remains dead.

Rekkid · January 25, 2022, 3:36pm

yes, emmc must be >= than SD card
sda, mmcblk and etc. – can different for everyone, use lsblk in terminal to identify what if what

to flash emmc - u should use emmc to sdcard to usb adapter (easy* way) or google how to do it (i didnt do that, dd from sd card suite me)

I dont want to make my hdd and ssd bootable, gonna stay on emmc. No secret reason here, just easier for me to play with emmc rather than hdd with 500gb+ storage

p.s. good to hear that fan is working now
https://wiki.radxa.com/Device-tree-overlays

check this one, maybe it will help with lcd (read carefully, choose RK3566/RK3568 Available Overlay (ROCK 3 A, ROCK 3 B, Radxa CM3) if that your case)

Karl-W · January 27, 2022, 8:45am

Yes at least . and it is not really getting warm,
The ROCK PI QUAD SATA HAT I Do own siince more than a year is porducing much more heat! in comparism

LCD is still not working.

Ideas how to fix ? cat /boot/uEnv.txt Shows the followig

Cannot find anything about LCD plus the Button in the Link you mentioned :-((

sorry for the format and not seeing your request ,I was ofsite for some time!

Karl-W · February 24, 2022, 7:11pm

Any hints?
Somehow it works and the fan is rotating. Still i do have an uncertain Feeling regarding Stability.
Will there be an updated patch/Install process to prevent a full reinstall from the scratch.
Especially as the LCD still is dead.
