i2c issue: argon one fan not working

Wed Jul 01, 2020 2:47 am

Hi

I installed the argon one fan scripts (https://download.argon40.com/argon1.sh) on a newly-downloaded 32-bit version of raspberry pi os. The in-built fan does not operate, even when temperatures get up to 70 degrees C.

The dmesg queue is filled with messages like this:

Code: Select all

[47727.666325] i2c-bcm2835 fe804000.i2c: i2c transfer timed out
[47758.706878] i2c-bcm2835 fe804000.i2c: i2c transfer timed out
[47789.827417] i2c-bcm2835 fe804000.i2c: i2c transfer timed out
[47820.867972] i2c-bcm2835 fe804000.i2c: i2c transfer timed out
[47851.988531] i2c-bcm2835 fe804000.i2c: i2c transfer timed out
I am also unable to send i2c commands manually:

Code: Select all

$ sudo i2cset -y 1 0x01a 0xfe
Error: Write failed
This case and fan used to work well, but it's been sitting around for a few months and I only recently reflashed the SD card from scratch. I am trying to diagnose what could be causing the problem, namely hardware or software. I suspect software as it was working before but isn't working now. Any insights appreciated.

I'm running:

Code: Select all

$ cat /etc/os-release
PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"

Here is my /etc/argonone.conf file (it is vanilla):

Hello, I'm on the exact same situation. Did you find the fix ?

Thanks,

I got got a Argon M.2 case and the fan does not turn on. It's just a passive heat sink until this is figured out.

I'm seeing a lot Argon case posts lately.

I have a replacements for the stock Python script you can find my project here https://gitlab.com/DarkElvenAngel/argononed.
