Performing the command > mem_util 0x480BC000
gives:
Unhandled fault: external abort on non-linefetch (0x1018) at 0x400e9000
Bus error
this address is the Camera ISP register ISP_REVISION but the funny thing is none of the Camera ISP register can be read.
Other registers like I2C, or GPIO read/write fine. Anyone know if there's a kernel build parameter required to make this work?
