CrossStudio & USB JTAG - "M.G." - Oct 13 8:18:12 2008
I'm still trying to use OOCDLink JTAG under CrossStudio but without efects.
I get "Cannot identify target" message. This JTAG works fine with OpenOCD.
This is OOCDLink JTAG project:
http://www.joernonline.de/dw/doku.php?id=projects:oocdlink:2_oocdlinks
Schematic: http://tinyurl.com/68qkag
Channel A
ADBUS0 -> TCK;
ADBUS1 -> TDI;
ADBUS2 -> TDO;
ADBUS3 -> TMS;
ADBUS4 ->
ADBUS5 ->
ADBUS6 -> 1 if target present
ADBUS7 -> SRST in;
ACBUS0 -> TRST buffer enable;
ACBUS1 -> TRST;
ACBUS2 -> SRST buffer enable;
ACBUS3 -> SRST;
Channel B
BCBUS2 -> LED
BCBUS3 -> LED
In CrossStudio in "Generic FT2232 Device" I have:
Output Pins 0x0F0F = ADBUS0 - ADBUS3 & ACBUS0 - ACBUS3 ?
Output Value 0x0000
nSRST Mask 0x0800 = ACBUS1 ?
nTRST Mask 0x0200 = ACBUS3 ?
PID: 0xBAF8
VID: 0x15BA
All other are set to 0x0000.
What about this "ADBUS7 -> SRST in" input pin ?
JTAG Clock Divider is set to 25, Fast Memory Accesses=No.
What are the correct settings for this JTAG ?
How to set mask for led pins on channel B ?

Then just use OpenOCD? I suspect there's a reason you ask here and get no
satisfaction. Bet hey, I'd like to think I'm mistaken.
