I'm trying to get to the values of data stored in memory on the Beaglebone
Black and experiencing a very fundamental problem. I have the following C
code running in Linux.
int *p;
int value;
p = (int *)0x4A300000; // Start of PRU0 data ram
printf("p addr: 0x%x\n", p);
value = *p;
printf("value: 0x%x\n", value);
p prints fine but trying to print *p or value gives a Segmentation fault.
Can anyone explain to me what is going on and how I can get to the data
stored at a memory location on the BeagleBone?
Thanks,
Mike Pitman
