Hi again all:
Well, the problems with the serial port dissapeared :?, but now I have
another question:
I tried to write to the Flash memory, but I'm unable. I read the
documentation of the AT49BV322A and the code from jtagomat, but it
doesn't work. I tried this:
unsigned char *puntero=(unsigned char *)0x10000000;
NutSleep(2000);
puntero[0x555]=0xAA;
puntero[0xAAA]=0x55;
puntero[0x555]=0xA0;
puntero[0x10001]=0x30;
NutSleep(1000);
valor=puntero[0x010001]; // Read the value
sprintf(cadena2,"Leo: %X",valor);
ezlcd_print(global_lcd,NULL,cadena2); // print it at the LCD
But I always read 0xFF
But it doesn't work. What's happening?
I'm using TFTP boot method.
Thanks in advance.
