Hi team,
I have purchased an OLIMEX ARM-USB-OCD and an Ethernut 3.0e , but I am
unsure how to wire the connect them together.
The OLIMEX website
(http://www.olimex.com/dev/images/arm-jtag-layout.gif) shows a pinout
that is different from the Ethernut 3.0 hardware manual.
I assume that this will work??
OLIMEX USE ETHERNUT USE
1 VREF 7 VCC3
2 VTARGET 4 VCC3
3 NTRST
4 GND 2 GND
5 TDI 9 TDI
6 GND
7 TMS 5 TMS
8 GND
9 TCK 1 TCK
10 GND
11 RTCK
12 GND
13 TDO 3 TDO
14 GND
15 RST
16 GND
17 DBGRQ
18 GND
19 DBGACK
20 GND
But where do I connect the NMR (pin 6 on the J7 ethernut JTAG connector) to??
Cheers Douglas
