dtoverlay=tc358743
If four CSI-2 channels are used to connect C780B to CM3 or CM4 computing module
hardware, the following code should be added.
dtoverlay=tc358743,4lane=1
2、Use "dmesg | grep CMA" to check the amount of memory allocated to the CMA heap.
pi@raspberrypi:~ $ dmesg | grep cma
[ 0.000000] cma: Reserved 256 MiB at 0x000000001ec00000
If the report has less than 96MB of files assigned to CMA, edit / boot / config.txt and add.
dtoverlay=cma,cma-128
