Striding forward like a boss

Saturday 28 April

Ok, much better news now. I managed to patch the 5 pins on the SDRAM on the board, making it the ugliest board with SDRAM I've ever seen...

with a close-up of the ugliness looking like:

... yeah...
 
HOWEVER, when I plug in the XTAG adaptor board (connects the Mac to the XMOS cpu via USB) as in the first photo above, I get a green LED (generally a good sign) and if I then scan for devices, I get:


sh-3.2$ xrun -l

Available XMOS Devices
----------------------

ID
Name Adapter ID Devices
-- ---- ---------- -------
0 XMOS XTAG-3 3CUoiRh. O[0]

Which is XMOS's way of declaring an 'O' type device at node 0 in the chain, connected via an XTAG-3 adapter board. By contrast if I unplug the xe-interface board from the XTAG and do the same scan, I get:


sh-3.2$ xrun -l

Available XMOS Devices
----------------------

ID
Name Adapter ID Devices
-- ---- ---------- -------
0 XMOS XTAG-3 3CUoiRh. None

So I now have communication to the on-board XMOS chip at least. Now I can start exploring the various peripherals, installing a simple LED flasher onto the XMOS chip (the hardware equivalent of the standard software 'hello world!' application) and then I can try plugging it into the 1088XEL and see if I can source power correctly from the bus.
 
So, much better news than last night icon_smile
