I received my Digilent JTAG programming cable ($12 + shipping)
today. I am to the understanding that it can be used to program the
Carte Blanche card (slower than the more expensive cables). It has a
PC parallel port connector on one end and a JTAG3 with SPI connector
on the other.
The JTAG end is a single inline female for six pins labeled:
TMS
TDI
TDO
TCK
GND
VDD 1.8 to 5.5v
The Carte Blanche connector is male dual inline five pins in each
row.
Obviously not a match but the Carte Blanche card comes with a
matching female ten pin connector with individual leads, each with a
single female connector.
I figure I can run wires between the female connectors on the one
cable to the ones on the other if I can figure out which goes where.
The Carte Blanche cable connectors are labeled:
SOFT TMS
SOFT TDI
SOFT TDO
SOFT TCK
HARD TMS
HARD TDI
HARD TDO
HARD TCK
GND
CONNECT
Do I connect to the Digilent cable to the SOFT or the HARD pins or
both?
Also the CB schematic shows the CONNECT pin as VREF (whatever that
is). It also says "IF YOU ARE CONNECTING THIS INTERFACE TO USER
BOARD A OR USER BOARD B DO NOT CONNECT THE REF PIN. REFER TO THE
APPLELOGIC WEBSITE FOR DETAILS". Unfortunately, the Applelogic
website seems to be down. So before I fry my CB card can anyone
give me a heads-up on what to do?
