   Of course - you need change COM1 to your port.

   I went there and looked at the .png file (on Window and Linux to see if something was broken on my side) and all I saw was two headers -- 20-pin and 8-pin and no connecting lines.
   Well, if I can't have lines, can I have some text?
   I know TDO <-> TDO, TDI <-> TDI, TMS <-> TMS, TCK <-> TCK, TRST <-> TRST, Vcc <-> Vcc, Gnd <-> Gnd.
   I am guessing that TRST also goes to nRESET.
   When I went from 20-pin to 10-pin I had to add in a handful of pull up/down resistors.

   20-pin ...................... 10-pin
   use .pin .................... pin use

   3.3V 1 ---+------------------- 1 3.3V
   ..........|
   VREF 2 ---+
   TRST 3------------------------ 10 TRST
   GND 4,6,8,10,12,14,16,18,20 --- 2 GND
   TDI 5 ------------------------- 3 TDI
   TMS 7 ------------------------- 6 TMS
   TCK 9 ------------------------- 7 TCK
   RTCK 11 ----------------------- 4 RTCK
   TDO 13 ------------------------ 5 TDO
   RESET 15 ---------------------- 9 RESET
   DBGRQ 17 N/C 8 N/C
   DBGACK 19 N/C

   20-pin 1 connects through 10K resistors (4) back to pin 3,5,7,13 (pull up)
   20-pin 4 connects through 10K resistors (2) back to pin 9,11 (pull down)

   I *think* I can just make up a 8-pin <-> 10-pin adapter:

   10-pin ..... 8-pin
   pin use ... pin use

   1 3.3V ----- 7 Vcc
   2 GND ------ 2 Gnd
   3 TDI ------ 5 TDI
   4 RTCK ----- ?????
   5 TDO ----- 4 TDO
   6 TMS ------ 6 TMS
   7 TCK ------ 3 TCK
   8 key
   9 RESET ---- ?????
   10 TRST ----- 1 TRST

   2 questions remain:

   1 hook up RESET to TRST
   2 RTCK is No Connection or TCK?

   Any directions available?

   Yey! I got it to work with Crossworks!

   With Activestate python 2.7 I had to change serialwin32 to serial and .Serial() to .serial_for_url().

   Now the next question is: How do you build a non-libmaple based binary and still use Maple's bootloader. Is it just a matter of setting up the right starting memory and using dfu-util?

   Hmm. Was this question asked already?
