Hi,
just for the mapping, you won't need most of the include files.
I often include xyz.h in xyz.c so that I get at least a warning when I
change
sth. so that the public promises in .h no longer hold.
pru_if.h is in the post but not needed.
Remove the includes and the compiler will tell you what is missing.
You definitely don't need ltcsrv.h and the stuff for nice().
* A file descriptor must be used for /dev/mem:
int dev_mem_fd;
dev_mem_fd = open("/dev/mem",O_RDWR | O_SYNC);
* Shared RAM is mapped (prepared for use) by this line:
shared_ram = (int *) mmap(NULL, 12*1024, PROT_READ | PROT_WRITE,
MAP_SHARED, dev_mem_fd, 0x4A300000 + 0x10000);
* Here follows examples of usage (in this case, writing to shared
ram memory):
shared_ram[0] = ... ; //write to 0x4A310000
shared_ram[1] = ... ; //write to 0x4A310004
shared_ram[1] = ... ; //write to 0x4A310008
^!!
Am I right?
Yes.
I should have snipped a lot of text, but was only half awake.
Cheers, Gerhard
