RE: [ts-7000] I need Memory Map for RTC TS-5620

["Daniel Perron" <>]

This is a little code I wrote long time ago to get the rtc memory on the TS7200.

 

 

 

#include<unistd.h>

#include<sys/types.h>

#include<sys/mman.h>

#include<stdio.h>

#include<fcntl.h>

#include<assert.h>

#include "peekpoke.h"

#include "rtc.h"

 

volatile unsigned char * RtcAddress=NULL;

volatile unsigned char * RtcData=NULL;

int RtcHandle=-1;

 

int InitRtc(void)

{

RtcHandle = open("/dev/mem",O_RDWR);

if(RtcHandle<0) return(0);

 

 

 

RtcAddress= (unsigned char *) mmap(0,getpagesize(),PROT_WRITE|PROT_READ,MAP_SHARED,RtcHandle,0x10800000UL);

if(RtcAddress == NULL)

{

CloseRtc();

return(0);

}

RtcData = (unsigned char *) mmap(0, getpagesize(), PROT_READ|PROT_WRITE, MAP_SHARED, RtcHandle, 0x11700000UL);

if(RtcData == NULL)

{

CloseRtc();

return(0);

}

return(1);

}

 

 

void CloseRtc(void)

{

if(RtcAddress)

{

munmap((void *)RtcAddress,getpagesize());

RtcAddress=NULL;

}

if(RtcData)

{

munmap((void *)RtcData,getpagesize());

RtcData=NULL;

}

if(RtcHandle>=0)

{

close(RtcHandle);

RtcHandle=-1;

}

}

 

unsigned char ReadRtc(unsigned char address)

{

*RtcAddress= address;

return(*RtcData);

}

 

void WriteRtc(unsigned char address, unsigned char value)

{

*RtcAddress= address;

*RtcData = value;

}

 

 

int ReadRtcBlock(unsigned char address,unsigned char size,unsigned char * block)

{

short loop;

short endp= (short) address + (short) size;

if(endp>128) //can we change that to a bigger value?

{

endp=128;

size= endp - address;

}

for(loop=address;loop<endp;loop++)

*(block++)= ReadRtc(loop);

return(size);

}

int WriteRtcBlock(unsigned char address,unsigned char size,unsigned char * block)

{

short loop;

short endp= (short) address + (short) size;

if(endp>128)

{

endp=128;

size= endp - address;

}

for(loop=address;loop<endp;loop++)

WriteRtc(loop,*(block++));

return(size);

}

I Use real Time Clock TS-5620 in TS-7200. I need Memory Address of Non
Volatile RAM.

Urgent... please

/*******/

Para los Hipanos.
Necesito usar la memoria no volatil del Reloj de Tiempo Real del TS-
5600, lo instalé en un 7200 y solo tengo la dirección para un pc
standard (070 y 071), la necsito para el 7200 arm

Gracias
