Simple question to owners of the W65C816SXB sbc:
Just received a board, had a few bent pins, not too bad, straightened them out and powered the board. SHOULD I get a monitor prompt
when using a serial terminal emulator? I do not, using both 9600 and 57600 baud, 8-bit, 1-stop, no parity. I see nothing, even garbage.

Using linux, cu and gtkterm, changed USB cables (2x) and see /dev/ttyUSB1 when the board is plugged in. Also tried sxb.py after change
of python code to reflect correct serial port.

Believe I got a bad board, just want to double check with someone that has this board.

Spoke to tech support at WDC and no, you'll have to use some python scripts to speak to the board, which he sent to me.
The board expects some code from the pc, then established communications. Probably best if your using Windows, as there are tools,
but in the Linux env your kinda stuck using python.

So, were you able to get the thing running?

Yes to a degree. But trying different things, like wine and trying to resurrect a windows laptop (v8.1 bare metal).
Then I'll pick. I am sooo use to the Unix development env (command line) that windows dev env looks weird.
Hope that old laptop still works....

FWIW: I have a W65C134-SXB board. (65C02 CPU) It needed no special tools - I use minicom under Linux to talk to it.

I seem to recall that it is fussy about handshake signals, but it all seemed to just work via USB back to my Linux systems.

I did a thing here on it:

However the '816 board may well be very different.

Andy, saw that post, and it's where I got the Python sxb.py from.

BTW: sxb.py no longer works on the newer versions of W65C816SXB even after changing serial port device in the code.
WDC tech support eluded to some changes in the firmware. NOT SURE if i should post the whole program i got from WDC
but i will post the lines of code where the python code wakes up the board:

def write_bin_command(self, cmd):
self.write_serial('55')
self.write_serial('AA')

the reply from the board is CC.
