I developed an driver for sensor mt9j003(a 10MP sensor with max resolution 3664*2748), and i modified the MAX_W and MAX_H to 4000*4000 in vip.c. it runs okay when i set the format of the sensor to 2592*1944, but when I set the format to 3664*2748, it crashed when i request 4 buffers for in mmap mode. the message as below.
