rear view camera with linux

Has anyone tried to communicate with the m41 rear view camera app using linux instead of android auto?

I have create a simple rpmsg to trigger the register event to m41.

M41 does receives it.

However it will fail when it calls

sc_rm_set_master_sid in SOC_AssignDisplayCamera function in isi_board.c

Any idea?

Hi,

Instead of trying to do it on Linux, i went with the easier step first. I tried to move lvds0(dpu 0) instead of lvds1(dpu1).

What i have done are:-

1. Set all related rsrc to movable in scfw

2. commented out #define USE_LVDS1 in isi_config.h and added as below in pin_mux.c

At this point, m41 is able to display

3. In Android, i have changed the device tree as attached.

4. When android starts, it will fail to display. From the console, i realize there is an error (it6263 5-004c: failed to wait for video stable)

Any idea?
