Failed to start media pipeline: -32 on pi5

pbaetens commented 5 days ago

Hello,

Pi5 / latest self-compiled bookworm with custom image sensor driver. This driver worked fine on bullseye before.

When starting the stream, I get this error in DMESG.

any idea how to debug this?

[ 1662.265013] rp1-cfe 1f00110000.csi: Failed to start media pipeline: -32

What sensor are you trying to use?

It's likely that your sensor media entity is not correctly configured on one of the ports. The best bet is to look at the media graph using media-ctrl -d /dev/mediaX -p where X is the media device node for your sensor.

2 sensors are connected. mira016 does not work, mira050 does work media-ctl output looks fine to me.

naushir commented 5 days ago

I can't see anything obvious that's wrong with that setup. What command line are you using to drive the camera?

naushir commented 4 days ago

Another thing to do is add (or re-enable) logging in this cfe_video_link_validate in the driver: https://github.com/raspberrypi/linux/blob/18d185166ca00c9280505ad41fbe036efbb52e67/drivers/media/platform/raspberrypi/rp1_cfe/cfe.c#L1661

This might point to the what may be wrong with the config.

Any update on this?
