SOLVED sc132 could not find component vc.ril.rawcam

maxlem

Hi I tried for over 1 hour to make my sc132 work with my rpi4 model b, running buster.

I enabled the camera and i2c via raspi-config
I ran the
./enable_i2c_vc.sh
./camera_i2c_config

and used the cs_mipi_i2c.sh script to read and set videofmt
everything seems normal

but when I try
./veye_paspipreview -md 1 -t 20000 -p '0,0,1200,720'
hardware version: c03112
before create camera com
mma1: mma1_component_create_core: could not find component 'vc.ril.rawcam'
mma1: Failed to ....
...
mma1: Camera not detected

I tried 3 times to reconnect the cable.

Please help!

Thank you

@maxlem Is your OS version 32-bit or 64-bit?Legacy mode should only support 32-bit.

Hi, thanks for replying.

I'm using 32bits:

lsb_release -a
No LSB modules are available.
Distributor ID: Raspbian
Description:    Raspbian GNU/Linux 10 (buster)
Release:        10
Codename:       buster
pi@raspberrypi:~ $ uname -a
Linux raspberrypi 5.10.17-v7l+ #1403 SMP Mon Feb 22 11:33:35 GMT 2021 armv7l GNU/Linux
pi@raspberrypi:~ $ getconf LONG_BIT
32

I can see the i2c part is working:

./cs_mipi_i2c.sh -r -f productmodel
PRODUCT MODEL is CS-MIPI-SC132
./cs_mipi_i2c.sh -r -f mipistatus
r mipi count 16953, mipi state 1
./cs_mipi_i2c.sh -r -f i2caddr
r i2caddr  0x3b

Thank you!

I think the pios version you're using lacks support for the legacy camera protocol stack. It would be better to try a different OS version. Here is a reference documentation for your information.

Hi, thanks again for the answer. What version do you suggest I used?

The article you point at talks about a special case for "Legacy camera interface" for bullseye. My understanding is that I need that legacy interface for your camera. On buster it is supposed to be built in. Isn't it what I did activate with raspi-config when I enabled the camera. Is that something to look for in the kernel logs or dmesg to know for sure what the source of the problem is?

I don't mind upgrading my pios version though. But I'd prefer not to blindly try many versions without really knowing the source of the problem

Thanks

@maxlem
ok I was using the Pi Os Lite version, with the full version (still on buster) it worked without issues.

Thanks for your help
