Thanks PetrockBlog! I just installed the Control Block on a Raspberry Pi 4 but due to the cooler I had to use dumont connectors - turns out i had 2 wires crossed - which solved my issue.

One question I do have now though... On my RP3 i got a message when i hit my shutdown button that shutdown script had been initiated and it was shutting own. It was a quick screen of terminal text.

On the RP4 though - The system just shuts down and there is no text regarding the shutdown script. Can you confirm on the RP4 this is correct? Or is there a way i can check to ensure the controlblock is running the shutdown script and i'm not just cutting power?

Thanks :)

Glad to hear that!
The PowerBlock only cuts the power if it observes the corresponding signal.
You should be able to see log entries of the PowerBlock in the log file /var/log/syslog.

@petrockblog Thanks!

I had a look at the system log and here are the first few lines of when i started the shutdown.

May 17 22:38:30 retropie systemd[1]: Stopped target Sound Card.
May 17 22:38:30 retropie systemd[1]: Stopping Session c1 of user pi.
May 17 22:38:30 retropie systemd[1]: Stopped target Multi-User System.
May 17 22:38:30 retropie systemd[1]: rpi-eeprom-update.service: Succeeded.
May 17 22:38:30 retropie systemd[1]: Stopped Check for Raspberry Pi EEPROM updates.

Does that look right to you? Or what should i be looking for?

Thanks!

Sorry, I confused it with the PowerBlock.
The logs of the ControlBlock should be in in the file /tmp/controlblock.log.

Looks like it's calling the Shutdown in the second last line!

Hey @petrockblog

Have you heard about any undervoltage warnings when using the control block with a Raspberry Pi 4?

Ever since I switched it over to my Rp 4 i've been getting under voltage warnings. I'm using the same canakit power supply i used on my Rp3 through the control block. The only USB device i have plugged in as a logitech wireless keyboard dongle.

Any ideas?

Cheers!

Answered my own question. I'm using a Canakit 5v - 2.5amp Mirco-Usb raspberry 3 charger.

Because the PI4 requires 5.v at 3 amp my Canakit Micro Usb is underpowering it via the Micro Usb power on the RP4.

To rectify this I ordered the "Argon ONE Raspberry Pi UL Listed Power Supply 5.25 Volts 3 Amps" off amazon.

I'm certain this will resolve my under voltage issues.

@k0zmir Post for Postery incase anyone else runs a control block on a pi 4.

What you need to actually do is buy a USB C to MICRO USB adapter to use on the USB C power supply. After ordering a new 3 AMP micro usb power supply, I noticed that the offical pi 4's run at 3.5 amps. I didn't realize at the time USB C to MicroUSB adapters existed.

Hope this post helps someone.
