Electrical specifications for camera port on Pegasus

Hello,

we are currently running into some issues running multiple IMX424’s from a single camera port (using the squid).

On one of our Pegasus devices we can easily run up to 3 cameras in parallel.

On two others, this does not work (with the exact identical software).

We are trying to understand what the difference could be.
Are there any specifications in regards to allowed power draw from a single camera port? Would there be any diagnostics on current overdraw?

Thanks.

Hi philip8g86p,

What command line are you using? Any suspicious message in log of the failure? What did you mean ‘using the squid’?

Hi VickNV,

I am from the same company as philip8g86p and can provide more details. Our current setup is with two cameras plugged into Port B on the green and red cables but we have tried on Port C as well.

Hi michael37fwb,

It seems something wrong in image capture. You can check if any suspiciuos kernel message on this.

But the messages you provided looks not from Drive Software 10.0 (Drive OS 5.1.6.1). Please help upgrade to the latest version and have it a try. Thanks!

Dear michael37fwb,

The sample seems to have been built by Sony team and provided to you.
If yes, could you please check this topic with Sony team?
Because there is no Sony camera info in ddpx-x.conf files. Thanks.
