yes I tried to develop on the W65C816SXB it was a nightmare... the developement system from western design center is just awful I was in contact with western design center, they never said anything about the bugs even though I asked them if something was going wrong... letting me believe that the problem was in my code (I was developing a monitor for the 6502) after having spend days on this problem I tried on a real 6502 and my program worked perfectly finally I analysed the schematics of the board.... and designed my own board to try to understand the problem and try to find a fix.... I had the stupid idea to use a w65c51 and once again a nightmare started.... to solve the serial port problem I had to replace the w65c51 by a g65sc51 (working perfectly) in fact I have a fix with my board and my fix activated my monitor work on 65c816 in emulation mode for me the problem is solved I trash all the western design center product I have and I'll never use them again Le 12/02/2024 à 15:27, A.
