Hi,

We are currently porting our RGB IMX715 camera to JetPack6.1 on the Orin Nano. We see the following messages (dmesg) when recording the camera:

The RGB camera is currently generating test images using the test pattern mode. In the image you can see that the image data was correct in JetPack 5.1.2 (upper image), but in JetPack 6.1 (bottom image) the data is corrupt.

This problem is very similar to issue :https://forums.developer.nvidia.com/t/camera-vi-jp-6-0-r36-3-fixes-for-raw-image-corruption-line-artifacts-through-vi-mode/299834
The proposed patches are included in JP6.1 … this is ok after verifcation (Device tree + source address.c)
Do you have any idea what is going wrong? We suspect problems with the DMA in module VI.

Do you mean the JP6.1 have problem?

Hi ShaneCCC

We completely reflashed our device with the latest Image version from the manufacturer of the edge devices we are using.
We dont have the tegra-mc errors anymore… We have still corrupted image but it seems, there was no relationship with these errors…
I think you can close this topic .
