SOLVED Jetson Nano B01 MV IMX264

Otca

Hi, I have used Image and DTB file from your github release and I recognize the camera well, but i got this error and obviously I dont have /dev/video0.
Also the ./mv_mipi_i2c.sh script works fine.

@otca by the way I dont see any Patches for 32.7.5:

nvidia_jetson_veye_bsp$ find . -name *l4t-r32.7*
./kernel_patch_4_mv/l4t-r32.7.3
./kernel_patch_4_mv/l4t-r32.7.1
./kernel_patch_4_mv/l4t-r32.7.4

could U please email or share it with me ?
also would u mind tell me how to apply the patch?
Thanks alot

@otca It looks like your Image doesn't contain the patches needed by the mv camera, so it reports an error: unrecognised data type.
Can I ask you the hardware and software version of your board, and which Image you replaced in it is from github?

@otca
"You did the right thing.
The Jetpack 4.6.5 version of the kernel does not yet support the MV series cameras.
Please switch to Jetpack 4.6.4 for your operations.

@veye_xumm well, I thanks you.
you helped me a lot long the pass and finally I was able to successfully work with the IMX264 on jetson Nano B01-Devkit 4GB jetpack 4.6.1 ( L4T 32.7.1).
i tested both cameras and both are Ok.
Still I have issues on other forum for Jetson Orin NX - Jetpack 6.0 (L4T 36.3).
Thanks

@otca I will continue discussing that issue with you in the other post.
