CrossStudio & USB JTAG

Started by "M.G." October 13, 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:

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.

I just did a OOCDLink-H cable work with CrossWorks for ARM, Release 2.0.8, using the "Generic FTD2232" target interface. The configurations used was:

srstXORMask="0x0400"
srstMask="0x0800"
trstXORMask="0x0100"
trstMask="0x0200"

OutputPins = "0x0f1b"
Output Value = "0x0c08"

jtagDivider="2"
fastMemoryAccessesEnabled="Yes"
usbPid="0xbafa"

The XML exported by CrossWorks for this target is:



I know that this post is old, but there isn't much information about how to configure a oocdlink-h with crossworks on the net, so I am posting here in case someone else needs it.
