First, let me say that programming isn't my thing, and from what I know about programming, "expecting expression" error is usually a systex error. So, looking at your systex:

proc_Ram_Map: process(Ah, downloading , RD , WR ,HW, SWdog_Rst )

begin
A16_F <= '0';
FlashRD <= Psen;
FlashWR <= '1';

if ((Ah =< "01000000" and downloading = '0')and ((WR'event and WR='0')or(RD'event and RD = '0'))) then
FlashRD <= RD;
FlashWR <=WR ;
A16_F <= '1';
end if;
end process;

Should there be a ' in WR'event and RD'event?? Maybe the computer is see the ' as part of the quote as in "A16_F <= '1'?"

It might be worth re-posting this question in the "Software & Programming" section of CR4 instead?
