FIRST, you forgot to mention what "does not work" means. Please be more specific.
Your reference links don't work, because the closing parenthesis is included.
If you follow the second link,
http://www.microchip.com/forums/m998867.aspx
you see that I was not able to read the UDID with IPE (worked in some previous version for the GB6 family) any longer for GB4 nor GB6 family. So I assume it won't for GA705 either.
If from there you choose the link you will get here:
http://www.microchip.com/forums/FindPost/981589
You will find the code how to access the UDID (and more memory locations)
For the GA705 family the Table 29-5 shows the UDID addresses, which you seem to have found.
UDID1
0x800F00
UDID2
0x800F02
...
UDID5
0x800F08
DS30010118B-page 340, <<< [
edit: continue reading thread -> Rev B is outdated and contains wrong addresses]
(Let's hope Microchip documented them correctly, documentation was wrong for the GB4 (other thread)).
The following code should do the job, replace the dbg* functions, they are custom display functions.
unsigned int j, wAddr, wData, wTablePag = TBLPAG; // save previous setting
TBLPAG= 0x80; // retrieve the PIC24 UDID
wAddr = 0x1600; // edit: 0x0F00 is wrong;
dbgPuts("UDID=");
for (j=0;j<5;++j)
{
dbgPuts("UDID");
dbgPutc('0'+j+1);
dbgPuts(" = ");
dbgPutHex( __builtin_tblrdh( wAddr) );
wData = __builtin_tblrdl( wAddr) ;
dbgPutHexW( wData );
wAddr += 2;
dbgPutLF();
}
TBLPAG = wTablePag;
