Tool/software:
Hi, TI expert!
I have a development environment for am6234, with our own evaluation board.
The software SDK version is PROCESSOR-SDK-LINUX-RT-AM62X-10.01.10.04.
We are currently porting the camera driver from SDK 8.6 to SDK 10.1.
In SDK 8.6, the camera can record videos normally, but it cannot in SDK 10.1.
The hardware related information is as follows:
1.The am6234 SoC chip does not have a GPU module inside.
2.The model of the MiPi CSI sensor we use is nvp6188, which supports the following video formats as shown in the picture
1.Device tree configuration information:
