[ts-7000] PLD registers, still not getting access to memory regs

["mattsaintdev" <>]

Hi,
posted a similar request a few weeks ago but after help still not 
getting a handle to the PLD registers of the video card.

Once problem was that i needed to be SU to do an open on "dev/mem" 
but still the pointer to "pld_regs=(unsigned char *)mmap(" is 
returning a -1. Checked page size btw which is 4096.

I dont have a problem mapping the video buffer though?

Code below, any suggestions?

Thanks

Matt




#include <unistd.h>
#include <sys/types.h>
#include <sys/mman.h>
#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>

volatile unsigned char *pld_regs;


int main(int argc, char **argv)
{

   char base7;
   int mem_handle=open("/dev/mem", O_RDWR | O_SYNC);
   //
   // 0x11E0_0000 = PLD Register base address

   printf("mem handle = %d\n", mem_handle);

   pld_regs=(unsigned char *)mmap(0, 4096 , PROT_READ|PROT_WRITE, 
MAP_SHARED, mem_handle, 0x11E00000);


   if ((int)pld_regs=-1) {
      printf("MMap failed.\n Page size = %d\n",getpagesize() );
      exit(1);
   }
   //
   //
   //
   //
   printf("TS-7KV Register settings probe \n");
   printf("------------------------------ \n\n");
   printf("BASE+0 Board ID #1 = %X (documented as 0x41)\n", pld_regs
[0xE0] );
   printf("BASE+1 Board ID #2 = %X (documented as 0x20)\n", pld_regs
[0xE1] );

   base7=pld_regs[0xE7];
   if (base7 & 0x80) printf("ADC option is installed\n");
   if (base7 & 0x40) printf("CAN option is installed\n");
   if (base7 & 0x20) printf("J5 Set\n");
   if (base7 & 0x10) printf("J4 Set\n");
   if (base7 & 0x08) printf("J3 Set\n");
   if (base7 & 0x04) printf("J2 Set\n");
   if (base7 & 0x02) printf("J1 Set\n");
   //
   //
   return 0;
}
