[ts-7000] Re: program Wacth dog timer

["PeterElliot" <>]

Hi,

Here's the code I use:

volatile char *WDOGctrl;
volatile char *WDOGfeed;

WDOGctrl=(char *) mmap(0,4096, PROT_READ|PROT_WRITE, MAP_SHARED, mem_fd, 
0x23800000);
if (WDOGctrl==MAP_FAILED) { perror("mmap 1"); return 0; }

WDOGfeed=(char *) mmap(0,4096, PROT_READ|PROT_WRITE, MAP_SHARED, mem_fd, 
0x23C00000);
if (WDOGctrl==MAP_FAILED) { perror("mmap 2"); return 0; }

// Set watchdog off...
WDOGfeed[0]=0x05;
WDOGctrl[0]=0x00;

// Set watchdog to 8 seconds...
WDOGfeed[0]=0x05;
WDOGctrl[0]=0x07;

// Release memory before exiting program.
munmap((void *)0x23800000,getpagesize());
munmap((void *)0x23C00000,getpagesize());



Hope this helps,

PJE
