Failed to use Camera B with UC-444 rev C #100

Closed exbutterfly closed 1 year ago

exbutterfly commented 1 year ago

Hello, Thanks a lot for the documentation you provide. I'm facing an issue with this hardware : Pi Zero 2W + UC-444 rev C + 2xcamera imx219

Os : Raspi 32-bit bullseye

$ uname -a
Linux raspberrypi 5.15.84-v7+ #1613 SMP Thu Jan 5 11:59:48 GMT 2023 armv7l GNU/Linux

Camera A works fine

The error comes from i2cset -y 1 0x70 0x00 0x01.

I close this issue because i found the solution : GPIO pin 2 which correspond to I2C data link was badly welded. A continuity test confrms that. After refreshing weldings all be fine.
