TE0726: camera resolution change at demo1

[gelssen]

Hello,

I tried to change camera resolution from 1280x720 to 640x480 at demo1.
But camera doesn't response at all.

I made changes the followings:
1. At vivado design, video resize resolution is set to 640x480.
2. At fsbl_hooks.c, set vdma_in_init to be 640x480
3. At system-top.dts, camera resolution is set to 640x480
4. rpi-camera.c, I set sensor_640_480_90

After these changes, stiil camera doesn't working (no video).
Did I miss some changes other than the above ones?
or Could tell me how to change camera resolution at demo1?

Regards,

Hello,

At first you need to check if your camera config is working. You can put ILA core after csi_to_axis core in Vivado project and check for input stream.

Thank you for your reply.

I'll try your suggestion, but I want to make sure I didn't miss any other setting to change resolution.
Could you confirm it?

Thank you,

Hello,

Other resolution settings is in Linux configuration. You need to change framebuffer definition in subsystems/linux/configs/device-tree/system-top.dts

I 'll check internal signals.
