if it's using I2C, how about probing it once

melta101•5w ago

manually

ZacckOsiemo•5w ago

For context I am trying to get image feed off a imx219-160 camera on a raspberry pi 0 2w in headless mode

ZacckOsiemo•5w ago

using something like i2cdetect?

melta101•5w ago

it's trying to do sensor.init() but is unable to read the version ID

melta101•5w ago

yep

ZacckOsiemo•5w ago

Ok cool let me run it

ZacckOsiemo•5w ago

Linux land is just insane

ZacckOsiemo•5w ago

so big

ZacckOsiemo•5w ago

almost autosar

ZacckOsiemo•5w ago

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

ZacckOsiemo•5w ago

My cable could be wrong

Ming•5w ago

Are you trying to run a camera on a RPi5?

ZacckOsiemo•5w ago

on RPi 0 2w

Ming•5w ago

OK - similar chip...

melta101•5w ago

after that try acessing the chip ID register

32bitSaviour•5w ago

looks to me like an i2c comms issue

Ming•5w ago

It could also be not enbaled in the Device Tree

melta101•5w ago

i also feel the same

Ming•5w ago

Is there an overlay for I2C?

ZacckOsiemo•5w ago

software or cable

melta101•5w ago

ZacckOsiemo•5w ago

I just enabled. i2c on raspi config

ZacckOsiemo•5w ago

rebooting

ZacckOsiemo•5w ago

then trying again

ZacckOsiemo•5w ago

I added an overlay to enable the camera

dtoverlay=imx219

dtoverlay=imx219

ZacckOsiemo•5w ago

Ok so now I have this

ZacckOsiemo•5w ago

I seem to have enabled i2c

ZacckOsiemo•5w ago

but no camera yet

Ming•5w ago

That's a distinct lack of camera 🙂

ZacckOsiemo•5w ago

I think re hook up the cable maybe its not connected just right.

melta101•5w ago

is it logic high?

melta101•5w ago

check with a multimeter if the cable is logic high or not ifso then it a maybe cable prob then

melta101•5w ago

or pinctrl doesnt enable logic high

ZacckOsiemo•5w ago

I just watched a video and I realise the guy at the shop might have connected the cable upside down

ZacckOsiemo•5w ago

was in a rush and I just wanted it to work

ZacckOsiemo•5w ago

rebooting then we can check again

32bitSaviour•5w ago

Hurry potter.

ZacckOsiemo•5w ago

Upside down cable and I have signal

melta101•5w ago

do you mean the flex cable?

ZacckOsiemo•5w ago

yes sir

melta101•5w ago

Ahh, i have done that

melta101•5w ago

i feel you

ZacckOsiemo•5w ago

it's always a damn wire!

Ming•5w ago

No - we witnessed your debugging and problem determination skills!

melta101•5w ago

i need this kind of optimism everyday

melta101•5w ago

i need this kind of optimism everyday

ZacckOsiemo•5w ago

I need this kind of time to debug
