Pijuice service not starting - Dependency failed for pijuice.service #1062

Closed mroelandts closed 5 months ago

Device: Pi zero 2 + PiJuice zero Firmware: V1.6 OS: 2023-12-11-raspios-bookworm-arm64-lite

After a bootup the pijuice.service is not running.

> sudo systemctl status pijuice.service
○ pijuice.service - PiJuice status service
     Loaded: loaded (/lib/systemd/system/pijuice.service; enabled; preset: enabled)
     Active: inactive (dead)
Dependency failed for pijuice.service - PiJuice status service.
pijuice.service: Job pijuice.service/start failed with result 'dependency'.

After I check what the dependency was of the service

> sudo systemctl status dev-i2c\\x2d1.device
○ dev-i2c\x2d1.device - /dev/i2c-1
     Loaded: loaded
     Active: inactive (dead)
dev-i2c\x2d1.device: Job dev-i2c\x2d1.device/start timed out.
Timed out waiting for device dev-i2c\x2d1.device - /dev/i2c-1.
dev-i2c\x2d1.device: Job dev-i2c\x2d1.device/start failed with result 'timeout'.

Why is my i2c failing on boot? When I execute a sudo apt install pijuice-base --reinstall everything is back up and running! Meaning that the "Enabling I2C" from the postinst does activate it but does not enable it for next boot. First I though I did a bad job of soldering the header on it, but since the postinst can activate it, this might not be the case.

Any advice is much appreciated.

Seems something is disabling i2c-1 at boot. After boot can you check with raspi-config what teh status of I2C interfacing is?

I checked the I2C status in raspi-config. It was turned off ("no" was selected). I selected yes and now everything is fully working. I can reboot without issues. Great suggestion! Thanks for your help.

Does the pijuice-base enable the I2C interface in a different way? (and therefore not persistent across reboots) I never had this issue before with my other pijuices. Could it be cause this is a 64bit OS?

pijuice-base is supposed to do the same as raspi-config. Probably due too changes in recent versions of raspi-configit does not work any more.
