Hello,

We have a digital twin of Entron F008A120RM0AES camera module,
With the SIPL library we are able to recognize the DES, SER and the image sensor, but unfortunately we observe a CSI PLL Lock failed error,

After going through the forum, we found a similar issue mentioned below, and the reason for the occurrence of this error was mentioned as “no valid video stream is coming into the deserializer”

However, we do not see any explanation provided as to how this error was resolved

Please find below the SIPL for your reference,

Could you please provide us some tips or hints to resolve this issue?

It appears that, as indicated in the topic and based on the source file cdi_max96712.c line 3368, no valid video streams are being received by the deserializer.

Please note that support for camera drivers of camera modules not on DRIVE AGX Xavier Sensors & Accessories | NVIDIA Developer falls outside the scope of our forum assistance. I recommend reaching out to your Nvidia representative for further discussion and support.
