Pironman 5 - RGB fans

General
1

Hi all,

I have just installed my Pironman5 4 days ago.
I have an issue (or maybe not?):
The RGB fans are always “on” (LED lights and rotate) even I switch my Pi5 off.

I have followed the instructions (I think so) and I have modified the configuration file as:

BOOT_UART=1
POWER_OFF_ON_HALT=1
BOOT_ORDER=0xf41

… the OLED screen is turned off correctly .

Any idea?

Thanks in advance
Abdel

Try to update the kernel, Sudo rpi-update

Hi,

Thanks for your answer.

Yes, done sudo rpi-update … no success
( I have rebooted the Pi)

:thinking:

After confirming the configuration shutdown to deactivate the GPIO power supply
It is recommended that after safely shutting down the pironman5, you use a multimeter to measure the GPIO 6 shorting tab on the IO expansion board to see what the voltage is. Connect the positive terminal to the GPIO 6 shorting tab and the negative terminal to the GND pin.
And also after safe shutdown, measure the positive and negative of the IO expansion board fan pins to see what the voltage is at that point, let us know.

Hi ,

Thanks for your answer.

Well, I’m not confortable with these electric stuffs. :stuck_out_tongue_winking_eye:
Sorry.

Do you have a schema / images (or video) I can follow?

Thanks again
Abdel

What about you turn the pironman5 case off safely and use a multimeter to measure the positive and negative labeled on the picture to see what the voltage is.

Hi,

Thanks for your answer.
You rock!

Find attached the result of the measurements (after have switched the Pi5 off)

Do you mean that the fan pins of the IO expansion board and the voltage at the shorting tabs are both at 0 V when the chassis is turned off?
What system are you currently using and what is the system version?
Are you sure you executed the sudo rpi-eeprom-config -e command to configure the shutdown to disable the GPIO power?
POWER_OFF_ON_HALT=1

Hi,

My answers to your questions:

  1. Do you mean that the fan pins of the IO expansion board and the voltage at the shorting tabs are both at 0 V when the chassis is turned off?

    → Yes, both are 0 V when Pi5 is turned off

  2. What system are you currently using and what is the system version?

    → Here the result of a) cat /etc/os-release and b) uname -a:
    → a) :

    • PRETTY_NAME=“Raspbian GNU/Linux 12 (bookworm)”
    • NAME=“Raspbian GNU/Linux”
    • VERSION_ID=“12”
    • VERSION=“12 (bookworm)”
    • VERSION_CODENAME=bookworm
    • ID=raspbian
    • ID_LIKE=debian
    • HOME_URL= http://www.raspbian.org/"
    • SUPPORT_URL=“http://www.raspbian.org/RaspbianForums”
    • BUG_REPORT_URL=“HOME_URL/RaspbianBugs”
    • Abdoupepone@raspberrypi:~ $ lsb_release -a
    • No LSB modules are available.
    • Distributor ID: Raspbian
    • Description: Raspbian GNU/Linux 12 (bookworm)

    → b) :

    • Linux raspberrypi 6.6.74+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.6.74-1+rpt1 (2025-01-27) aarch64 GNU/Linux

  3. Are you sure you executed the sudo rpi-eeprom-config -e command to configure the shutdown to disable the GPIO power?
    POWER_OFF_ON_HALT=1

    → Yes, sure. As I wrote in my very first post:
    I have followed the instructions (I think so) and I have modified the configuration file as:

    *BOOT_UART=1*
*POWER_OFF_ON_HALT=1*
*BOOT_ORDER=0xf41*

Thanks.

HI. Are you still having the trouble of ‘fans staying on’ and ‘no OLED’?
I did as well on first power up. I found the fix on the page: Welcome to SunFounder’s Documentations! — SunFounder Documents documentation Select the tab ‘Online Tutorials’. Move down the list to Projects-Raspberry pi. the third option down is 'Pironman 5. Selct that. There is a video that includes, about 3/4 way along, the steps to install the ‘Pironmam 5’ which shows the line commands that you need to follow. The video is in “STEP 3” on the left. (there is a simailar one in “STEP 5” ) But for now, select 3, move down to the bottom on the right and hit ‘NEXT’ button. There is where the video is. Watch it a few times…then go to ‘STEP 5’ on the left and you can cut and past the commands you need to install the Pironman 5 . This as not and OS, it is a apt I think. The commnads toi find and change to POWER_OFF_ON_HALT=1 for example is there, which you have already done.
After I did this, and did a reboot, my RGB lights on the extender card came on, the OLED came on, and the fans now trun off when the machine is turned off.
I am brand new to this whole rAspberry Pi world AND to the Command line also. This took me a whole afternoon to weed through and get going. I really hope it goes much easier for you. All I can say is go slowly and watch the last part of the video a couple or three times . One video is about remote access, but the steps are the same .

Please contact our after-sales email: service@sunfounder.com
We will send you a replacement IO expansion board to see if it can solve your problem.

Hi Robert,

Thank you for anwser and advise.

Yes, I have followed this procedure.
But still have the RGB fans on after I have powered off the Pi5 (OLED is OK: it is switched off).

… Continuing on my investigations then.

Hi

Follow up of my issue: good news!
I have received a new IO expansion board, everything is working as expected now.

Thank you everyone for your help!
