Does Jetson Nano support MIPI D-PHY/CSI-2 continuous clock mode?

Hello NVIDIA,

Does Jetson Nano support MIPI D-PHY/CSI-2 continuous clock mode?

Hi t.kato1,

Yes, this is a property (“discontinuous_clk”) that can be modified the device tree. Check the following link for more documentation: Sensor Software Driver Programming — Jetson Linux<br/>Developer Guide 34.1 documentation

Hi jchaves,

Thank you for your information.

Let me double check that just in case.

Jetson Nano Linux Version is 32.7.3.

Is Jetson Nano covered by Developer Guide 34.1?

Hi, t.kato1

No, as far as I know the JetPack 5.x.x releases and onward are supporting just the Jetson AGX Orin, Jetson Orin NX, Jetson AGX Xavier andJetson Xavier NX. The latest release that supports the Jetson Nano is JetPack 4.6.3 (Jetson Linux 32.7.3).

Hi jchaves,

Jetson Nano does not support “discontinuous_clk”.

Jetson AGX Orin, Jetson Orin NX, Jetson AGX Xavier andJetson Xavier NX support “discontinuous_clk”.

Is my understanding correct? I want to make sure.

[jchaves]

The Jetson Nano allows to use the “discontinuous_clk” property in the device tree, in your case since your original question was if continuous clock mode is allowed in the Jetson Nano then you would need to set that field in the device tree as:

discontinuous_clk = "no";

Additionally in my previous answer I was pointing out to the fact that the Jetson Nano is supported until JetPack 4.6.3 (Jetson Linux 32.7.3). So the most recent version for the Jetson Nano that you are available to use is that one.
