PiJuice not working or communicating

[jbmorris289]

Hi. My Pi has been having trouble communicating with my PiJuice. I cannot do much of anything with it. This is the error I get from pijuice_cli:

Traceback (most recent call last):

This smells like I2C is not initialized and/or the PiJuice has a changed I2C address.
Can you check the output from i2cdetect -y 1?
Which Pi and which OS? (output from cat/etc/debian_version and uname -a)

That would be interesting, because it was working before...

i2cdetect -y 1 returns:

Error: Could not open file `/dev/i2c-1' or `/dev/i2c/1': No such file or directory

I have a Pi 4 Model B, 2GB.
This was the output from those two commands:

12.8
Linux [hostname redacted] 6.6.31+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.6.31-1+rpt1 (2024-05-29) aarch64 GNU/Linux

You are obviously on Bookworm (Debian 12.8).
Has it ever worked after you upgraded to Bookworm?
Now config.txt is located in /boot/firmware.
The file /boot/config.txt now contains:

DO NOT EDIT THIS FILE

The file you are looking for has moved to /boot/firmware/config.txt

Suggest to run sudo raspi-config and under Interfaces enable I2C.
After a reboot /dev/i2c-1 should show up and i2cdetect -y 1 should work.

Yep, bookworm. Now I don't remember if it worked after I upgraded it.

That did it. Guess the setting is off by default - I did a headless install. Results:
