@veye_xumm
Sorry for the late reply.
Thank you for the new code!
It seems to work partially in the rpi5 standard OS. I was able to compile the read and write files, and some commands work while others don't.

The new mgain is stuck at zero, so if i use new exp mode i can set the shutter speed with new mshutter, but not the new mgain, despite changing it returns zero when i probe with the -r parameter. so using the new exp mode i only get a black image.

the old mshutter works and i was able go get up to 1 second exposure per frame in streaming mode but the capture mode and capture command don't seem to work.

Also i would like to have it work in the rpi archlinux OS that i use for astronomy. The veyecam2m driver works and i get video in the archlinux OS, but i wasn't able to compile the i2c read and write in that system.

@veye_xumm when i run ./make.sh i get

i2c_read.c: In function ‘main’:
i2c_read.c:112:42: error: passing argument 4 of ‘i2c_rd’ from incompatible pointer type [-Wincompatible-pointer-types]

i already tried the ./veye_mipi_i2c.sh with the -b set to 10, 11, 6, 4 and 0. all give the same results.

@veye_xumm the -b parameter makes no difference, i tried all the possible bus numbers and still get all the wrong answers. for example:

~/raspberrypi/i2c_cmd/bin (master*) » ./veye_mipi_i2c.sh -b 11 -r -f hdver
hardware version is 0xff
release date is 20ff-ff-ff

I was able to set new expmode to manual:
~/raspberrypi/i2c_cmd/bin (master*) » ./veye_mipi_i2c.sh -r -f new_expmode
r new expmode is manual, use new_mshutter and new_mgain

But when i try to set the new_mshutter i get:
~/raspberrypi/i2c_cmd/bin (master*) » ./veye_mipi_i2c.sh -b 10 -w -f new_mshutter -p1 1000

awk: cmd. line:1: (FILENAME=- FNR=1) fatal: division by zero attempted
./veye_mipi_i2c.sh: line 1290: [: -gt: unary operator expected
./veye_mipi_i2c.sh: line 1294: >>8: arithmetic syntax error: operand expected (error token is ">>8")

@brunosaisi said in veye-mipi-IMX462 on rpi5 get video stream but cant controll via v4l2 or i2c:
I also tried v4l2-ctl -d /dev/v4l-subdev2 -l

and get:

~ » v4l2-ctl -d /dev/v4l-subdev2 -l

Image Processing Controls

pixel_rate 0x009f0902 (int64) : min=74250000 max=74250000 step=1 default=74250000 value=74250000 flags=read-only

I am trying to use the module for guiding in astrophotography (Astroarch system on an rpi5), and there is an indi-v4l2 driver that recognizes the camera but can only play the video stream, not take singe exposures or control exposure and gain via v4l2. Being able to use the standard v4l2 controls would be ideal.

I managed to install the veyecam2m driver and get video on dev/video0, but when i try v4l2-ctl -d /dev/video0 -l I get nothing back, no controls available for this device.
I also tried the i2c_cmd method, built the read and write from source, and when i call for camera_i2c_config i get

~/raspberrypi/i2c_cmd/bin (master*) » ./camera_i2c_config
setting GPIO for board revsion: d04170
Failed: don't know how to set GPIO for this board! Type is 17
Use i2c-10 for the sensor (-y 10)

when i try veye_mipi_i2c.sh commands the answers are all wrong:

~/raspberrypi/i2c_cmd/bin (master*) » ./veye_mipi_i2c.sh -r -f devid
device id is 0xff

~/raspberrypi/i2c_cmd/bin (master*) » ./veye_mipi_i2c.sh -r -f boardmodel
Board model is VEYE-MIPI-327

~/raspberrypi/i2c_cmd/bin (master*) » ./veye_mipi_i2c.sh -w -f cameramode -p1 0x1
w cameramode is 0x 1

here i thought i had set it to manual mode, but no:

~/raspberrypi/i2c_cmd/bin (master*) » ./veye_mipi_i2c.sh -y 10 -r -f cameramode
r cameramode is 0xff

Can u shed some light? Thank you!
