@veye_xumm Okay, thank you very much for the replies.

@veye_xumm

I'm now trying to change the strobe duration, but I'm unable to.
The strobe is synced with the framerate and the strobe duty cycle is about 4%, but I'd like to increase it.
I'm trying to do:

./mv_mipi_i2c.sh -r -f trgexp_delay -b 6
./mv_mipi_i2c.sh -r -f trginterval -b 6

and I'm reading back those values to verify that they have changed, but the strobe duration doesn't seem to be changing.

Hi. Thank you very much for your reply.
It worked.
(Edited to add answers.)

• I downloaded the bin file, but how do I use/run/apply it?
  Answer. This explains it: https://wiki.veye.cc/index.php/Mvcam_firmware_update_manual

• What is stream mode?
  Do you mean the result you get when you run: ./mv_mipi_i2c.sh -r -f trgmode -b 6
  In that case, I'm in mode 0 (Video streaming mode). Is this what you were asking?
  I'm configuring the camera using: v4l2-ctl --set-ctrl frame_rate={framerate} -d {subdevice}
  And I'm reading frames in C using v4l2_open(), v4l2_mmap(), etc.

• Do I need to turn some strobe setting using the I2C interface in order to activate the strobe?
  Answer. No, I think. I think you only need to make sure you're in streaming mode, but that's the default I think.

I'm using an IMX-287M on the Raspberry Pi 5 to record video at over 500 FPS.
I'm using an LED PCB to light the scene.
The LED PCB is controlled by the Raspberry Pi 5.
The LED PCB can be turned on by setting a Pi 5 GPIO pin to 1 and it can be turned off by setting the GPIO pin to 0.

How can I synchronize the video capture on the IMX-287M to the GPIO pin of the Pi 5 so that the LED PCB turns on when the IMX-287M is capturing a video frame (during exposure) and turns off the rest of the time?

That it, how can I turn on/off the LED PCB in sync with the video capture of the IMX-287M?

@etale_cohomology

I think something is still missing, because I still can't run ./mv_mipi_i2c.sh successfully.

For example,

./mv_mipi_i2c.sh -r -f manufacturer

returns

Manufacturer 0 not recognized

./mv_mipi_i2c.sh -r -f model

returns

model 0 not recognized

EDIT

It turns out you must manually select the I2C bus number (I also enabled I2C on raspi-config). Since I'm using CAM0 on RPI5, the bus is 6. Example:

./mv_mipi_i2c.sh -r -f manufacturer -b 6

This works.

@veye_xumm

Thank you for your reply.

I'm using the files here:

https://github.com/veyeimaging/mvcam_raspberrypi/tree/392451009cc93cfd56bd3c0096c329e7a429f6f8/mv_tools_rpi

and, according to the docs, before running mv_mipi_i2c.sh I must run

./enable_i2c_vc.sh
./camera_i2c_config

but ./camera_i2c_config is failing with:

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)

(I'm running a Raspberry Pi 5.)

I also tried the files here: https://github.com/veyeimaging/raspberrypi_v4l2/tree/c782fc464d76c5ed2a7f8f31df72eaaa51e0dceb/mv_tools_rpi
but same error.

How do I set the exposure for the IMX-287M?

I don't find anything about exposure here: https://wiki.veye.cc/index.php/Mv_series_camera_appnotes_4_rpi

I also tried:

v4l2-ctl --set-ctrl exposure=10000 -d /dev/v4l-subdev2

but it says:

unknown control 'exposure'

Maybe there's a media-ctl command?

I'm on the Raspberry Pi 5 on Bookworm with kernel 6.1.0-rpi7-rpi-2712

Hi, I'm trying to run the IMX287M camera on a Compute Module 4 running Bullseye 11 and Linux 6.1.21v8+.

I'm following the instructions in the Wiki:
https://wiki.veye.cc/index.php/Mv_series_camera_appnotes_4_rpi

I enabled I2C on the CM4, connected the power DuPont cables and installed the driver, but when running

dmesg | grep mvcam

I get the error

pi@raspberrypi:~ $ dmesg | grep mvcam
[    0.071124] platform fe801000.csi: Fixed dependency cycle(s) with /soc/i2c0mux/i2c@1/veyemvcam@3b

And I get no device on /dev/video0 (so I can't use the v4l2-ctl commands).
