My Pi4 dies when running any of the demo programs in https://github.com/ArduCAM/MIPI_Camera/tree/master/RPI, with or without the camera attached - e.g.

$ ./arducamstill -?
Open camera…
Hardware platform: a03111
Found sensor ov2311 at address 60

Then the pi dies and I lose my VNC connection. I’m connecting to the pi from my Mac, and the camera is an OV2311.

Any ideas for how to troubleshoot this? It seems like a hardware issue, but I’m curious what the camera programs are doing that could cause the pi to crash?

Thanks -

 

I tried the camera on a Raspberry Pi 3 and got it working - not sure what the problem with the 4 was.

Hi，

It seems to be the cause of pi 4, we will test and find the real cause.

I got an ov7251 to experiment with - https://www.arducam.com/product/arducam-ov7251-mipi-0-31mp-monochrome-global-shutter-camera-module-raspberry-pi/, along with another raspberry pi 4.

It’s still hanging when trying the demo programs. This time I ran strace to see what might be going on.

$ strace -o foo.txt ./list_format (hangs) (reboot)

$ wc -l foo.txt

Does this help with diagnosing the problem? It looks like it tries to print the formats correctly, but something else causes it to hang.

If you know of any other diagnostics I could run let me know.

My boot config is

 

# Uncomment some or all of these to enable the optional hardware interfaces #dtparam=i2c_arm=on #dtparam=i2s=on #dtparam=spi=on

[pi4]

Enable DRM VC4 V3D driver on top of the dispmanx display stack

#dtoverlay=vc4-fkms-v3d
max_framebuffers=2

[all]
#dtoverlay=vc4-fkms-v3d
start_x=1
gpu_mem=128
dtparam=i2c_vc=on

Thanks

 

Hello,

Don’t worry and I will try my best to help you.

It is due to our driver has disabled the wired network, we updated the driver, you can download the latest driver test.https://github.com/ArduCAM/MIPI_Camera.git

Feel free to let me know if you need more help.

 

That did it! I did

$ git pull $ make install $ make clean $ make

And now the demo programs work on the pi4 - thanks, bin

Hello,

You are welcome. Feel free to let me know if you need more help.
