Dear
I'm going to use CSI0 for using 4-lane and VC.
And I saw a document of r01us0553ej0110-rz-g(Release Note). There is a message as follows.
Could you let me know what the "SW limitation" means?
Hi Captain,Our team is investigating your query and one of our members will reach to you soon.Kind Regards.
I need your help.
Please, let me have your answer soon.
Thanks,
Hi Captain,
The commit for this limitation is here:
https://github.com/renesas-rz/rz_linux-cip/commit/4fde8e221ffaf4948388701d04ae778630f92428
RZ/G2M v3.0, G2N and G2H can support both CSI20 and CSI40 at the same time but we have to disable CSI40 as default setting with below reasons:
- 2 cameras that connect to CSI20 and CSI40 must be plug-in. It should be not lack of any camera.
- VIN can not be registered as a video device if any camera is missing.
So, if you want to use CSI20 and CSI40 in your board, just remember to connect 2 camera to 2 CSI-IFs and remove the property " status = "disabled";" in csi40 in r8a774a3-hihope-rzg2m-ex-mipi-2.1.dts for example.
Hi hienhuynh,
Appreciate your help.
I want to use CSI40 only via CSI0 and 4 VC(4 cameras on CSI0 through a muxer like TP2855 of Techpoint).
"" 2 cameras that connect to CSI20 and CSI40 must be plug-in. It should be not lack of any camera.""
It means that I cannot make it possible to work only CSI40 and CSI0.
If I'm misunderstanding, please, let me know the way to use CSI40 and CSI0 only.
You can use only CSI40 by adding "status = "disabled" in csi20 and remove "status = "disabled" in csi40 for their device tree nodes.
There is no problem for running only CSI40.
