Camera does not work properly on board with more than 4GB of memory. After the memory is upgraded from 4GB to 8GB, open the camera APP, the terminal will output:
[ 100.488782] rga_mm: RGA_MMU unsupported Memory larger than 4G! [ 100.488814] rga_mm: scheduler core[4] unsupported mm_flag[0x0]! [ 100.488821] rga_mm: rga_mm_map_buffer map dma_buf error!
