I've examined Raspberry PI 4 Model B schematics. According to schematics, camera connector has the following pinout and there is only one way to connect FFC cable to the connector.

I also checked that the GND pin is on the top and the 3V3 pin is on the bottom.

Entire connection diagram is as follows and this is the configuration I've used from the very beginning.

Since the camera connector allows FFC cable to be connected on both sides, I've connected cable with the opposite side.

In such connection scheme, the Raspberry Pi failed boot. It looks like there is a short circuit somewhere. But, Jetson Nano can handle that load ))) According to the readings from my power supply, power consumption increased from 2W to 10W and camera module gets extremely hot. It doesn't look like camera can work with such connection scheme.

Even after these experiments, I was able to connect to the camera and it did not report any errors.

user@raspberrypi:~/mv_tools_rpi $ ./mv_mipi_i2c.sh -b 10 -r -f manufacturer
Manufacturer is VEYE
user@raspberrypi:~/mv_tools_rpi $ ./mv_mipi_i2c.sh -b 10 -r -f model
model is RAW-MIPI-SC132M
user@raspberrypi:~/mv_tools_rpi $ ./mv_mipi_i2c.sh -b 10 -r -f errcode
errcode is 0x0 
user@raspberrypi:~/mv_tools_rpi $ ./mv_mipi_i2c.sh -b 10 -r -f snsreg -p1 0x301f
read sensor register addr 0x301f value 0xf

Apparently both my modules are damaged and this cannot be detected with software.

I also connected the camera module to the Raspberry Pi according to the instructions on the page https://wiki.veye.cc/index.php/Mv_series_camera_appnotes_4_rpi

To test the camera I used the following commands:

^C

The last two commands freeze.

I also tried using the qv4l2 application. As with Jetson, I got a black screen.

Is there a way to check camera modules for hardware problems?

@veye_xumm

Connections looks correct.

The following messages bother me

[ 3897.194907] mvcam 8-003b: camera_common_mclk_disable: no device power rail

Unfortunately this didn't help. The application shows a black screen, dmesg shows the same messages. I tried both cameras.

What else can I try?

Hi. I'm trying to make my RAW-MIPI-SC132M work on Jetson Nano Dev Kit. I am following the instructions on the wiki https://wiki.veye.cc/index.php/Mv_series_camera_appnotes_4_jetson

I enter the following commands:

v4l2-ctl -d /dev/video0 --set-ctrl roi_x=0
v4l2-ctl -d /dev/video0 --set-ctrl roi_y=0
v4l2-ctl -d /dev/video0 --set-ctrl preferred_stride=1088
v4l2-ctl -d /dev/video0 --set-fmt-video=width=1080,height=1280,pixelformat=GREY --stream-mmap --stream-count=-1 --stream-to=/dev/null

The last command stuck and nothing happens. At this moment the following entries appear in dmesg:

What is the correct way to capture images from the camera?
