Argon One V1 - Fan Control Not Working

[Techery]

Hello,
I was an early adopter and purchased the first version of the Argon One case back when it was released, I was very pleased with it but haven’t been using it lately. Today I decided I would set it up again, however upon downloading the software as per the instructions the fan no longer works in any capacity. When booting up an old OS with the software already installed it works perfectly. This has lead me to believe that the latest version of the software isn’t compatible, so I wondered if anyone knew any work arounds, ways to access old copies of the software or maybe a way to get it from the old OS.
Thank You

Hi Stephen,

the commands for the fan control hasn‘t changed for V1/V2. So the script should normally work. But it depends on the OS that is in use. For example the support for LibreELEC 10+ is not in place with the official distributed ArgonRemote.zip add-on or argon1.sh.

Please can you provide more details which OS you try to use, perhaps this makes the difference.

[Techery]

I have tried it on Raspberry Pi OS Lite (64 Bit), Raspberry Pi OS Lite (32 Bit) & Raspberry Pi OS (Legacy 32 Bit) Lite! Thank You

[HarryH]

Do you have installed additional HATs or packages/services like iobroker or something like that? This can blocking the GPIO pins or the I2C bus.

To test the fan without the script you can use these commands:

Please stop argononed service first, if you used argon1.sh before.
systemctl stop argononed

• Check if MCU address (1a) inside the case is reachable at I2C.
  i2cdetect -y 1

• Set the fan to 100% duty cycle:
  i2cset -y 1 0x1a 0x64

• Disable the fan, if you wish:
  i2cset -y 1 0x1a 0x00

[Techery]

All installations I tested it on were fresh installs so no non-standard packages would be installed & no installed HATs. When running the i2cdetect -y 1 I get the following, which seems to suggest that it isn’t detected. Any ideas why that would be the case, especially since it works on an old install?

Can you please check if your RPi4 is started with an outdated bootloader?
sudo rpi-eeprom-update

Additional, please post the content of your config.txt.

[Techery]

I ran rpi-eeprom-update and it was 3 years out of date so I ran the updater with sudo rpi-eeprom-update -a, however after doing so the fan is still not functional, and remains undetected using the i2cdetect command you mentioned earlier.
I wasn’t sure which config file you were referring too, but here is a copy of my argononed.conf file:

#
# Argon Fan Speed Configuration CPU
#
# Min Temp=Fan Speed
1=100

[HarryH]

I meant this one: https://www.raspberrypi.com/documentation/computers/config_txt.html
In the case of the new OS version it should be at /boot/firmware/config.txt

Regarding the bootloader update, do you have made the required reboot after you fired the ‘rpi-eeprom-update -a’ command? Do you double checked that the new version is in place? You doesn’t reported which date version it’s now. Unfortunately this is the only available indication which one you use.

What you should prevent to use is the i2cdump command, if used it before. This triggers the MCU to disconnect from the I2C bus. The same behavior I have observed if the MCU power button (hold button longer as 3 seconds and shorter than 5 seconds ) was triggered to initiate a shutdown or the remote control power button command has been received.

After such issues it’s required to remove the power supply from the case for some seconds, to get MCU back to normal.

Currently I don’t know, why the MCU with the old OS should behave other than with the current OS version: But is the always-on jumper in your case available and how is it currently set?

Hi Ya,
Having the same issue as ‘Techery’,
Raspberry pi os 12 64bit
has the Script changed recently?
Reinstalled a few weeks ago and it was working
Reinstalled yesterday and not working
i2c is active but not detecting Hat

@ranger1

Firmware is latest

Sorry, but this sentence does not contain reliable information. Please keep in mind that your post can be read a day later and possibly a new version was released overnight. There are also some stable boot loader releases that are ahead of the last DEFAULT version from 2023-01-18. So it’s needed to be more specific.

Which bootloader date and kernel version do you have?

I2C relies on a stable reference clock. Please can you check if these additional lines

enable_uart=1
core_freq=250

at the end of your config.txt makes a difference? Don‘t forget to reboot to activate the changes.

PS: Do you have seen, that you have the scope „[all]“ twice?

It looks to me that there some changes regarding the i2c bus are ongoing at kernel level:

Improve reliability at higher bus speeds

i2c failing to initialize and detect devices

Please remove the line “core_freq=250”, I found out today that there are problems with newer kernels and that the dmesg protocol is flooding.
Can you grep your dmesg log for i2c messages and also check what pinctl is reporting?
sudo dmesg -T | grep -i "i2c"
sudo pinctrl 2-3

As a shot in the dark, you can try forcing the I2C bus to a lower speed:
dtparam=i2c_arm=on,i2c_arm_baudrate=100000

Why do you have enabled SPI? Do you have a HAT attached?
Please try without these 2 lines too:

dtparam=spi=on
dtparam=sd_poll_once

[ranger1]

Thanks Harry

I’m booting from a usb ssd, is the reason for
dtparam=sd_poll_once. It WAS working with no issues.
Removed line
core_freq=250
#dtparam=spi=on
and added i2c_arm_baudrate=100000
rebooted

I’m going to reinstall with raspberry pi OS Bullseye on a sdcard.
It does look like a kernel issue, NO expert!
and hope for the best.

Thanks for trying
