Hello again,

I convert an Ascii file (about 10kB size) to HEX using the BIN2HEX and declaring a file start segment of 4800 (...absolute address 0x48000). When starting debugging in simulation mode using uVision2, I load it to my target (load MYFILE.HEX).

Using a far pointer I'm trying to read all the memory locations from 0x48000 to 0x4A400 but I get nil on the serial window.

I check the memory using the command "Display" and MYFILE is loaded in address 0x40000 (not 0x48000) and even when I redirect the pointer's offset to 0x40000 I still get nothing.

unsigned int i;	
	char far *pointer;
	pointer=0x48000; 
		
	for (i=0x0; i<0x2400; i++)
	{
		putchar(*(pointer+i));
	}

I use the small memory model with Near memory set to 32kB RAM. My ROM is 0x0-0x3FFFF.
And in case that helps...
.
.
FDATA (0x40000-0x4FFFF), FDATA0 (0x40000-0x4FFFF), 
HDATA (0x40000-0x4FFFF), HDATA0 (0x40000-0x4FFFF), 
XDATA (0x40000-0x4FFFF), XDATA0 (0x40000-0x4FFFF)) 
DPPUSE (0=NDATA(0x40000 - 0x47FFF), 2=NCONST(0x0 - 0x3FFF))
CINITTAB (0x10000-0x3FFFF)

Can you please help me with that? How can I read the loaded file?

Regards
George
