Just to add to this further, running the relay output seems to work fine.


a119b38:/opt/app# ./piTest-cmd RevPiOutput,0
a119b38:/opt/app#


Seems like the issue is just related to the LED control.

Looking in journal from the boot i'm getting a few errors related to picontrol

Hi again, seem to have another issue currently with writing to the LED variable via the pitest tool

I'm trying to read from the variable and getting this as the output



./piTest-cmd -r RevPiled,0
Failed to get variable info: No such file or directory
Failed to find variable 'RevPiled'
Failed to ...

Thanks for the reply thats worked perfectly!

Might be worth adding that to the base image and adding it to the official documentation!

Cheers

incase its useful running pitest gives me this output

Managed to get a working config.rsc from another revpi connect 4

Still unable to use piTest from a container so might be missing something there?

Hi, does this also apply for the relay? (https://revolutionpi.com/documentation/ ... lay-output)

thanks
Jack

Sorry to bring this up again, Is there any documentaion on using the Relay output when using balena OS?

Trying to get it setup for a remote power cycle setup and it seems that the balena OS image doesn't have the default config to enable the OI operations.

is this a unique thing for each REVPI 4 ...

Hi, only just seen this again, Managed to find it myself late last week came to the same solution!

Might be worth adding it to the docs!

Cheers

Hi all, I've got a RevPI Connect-4 Which is flashed with the balenaOS image and the RTC isn't showingup/working.

There doesn't seem to be a RTC device in the usual location (/dev/rtc*) and theres no mention in journalctl or dmesg about a rtc.

timedatectl returns this:
