Connection new LPC2103

Started by Michael Gerkens January 8, 2007
Hello all,

i have build a board with an ARM LPC2103, very simple.
But i can't get a Connection via JTAG to the Controller. I work with
CrossStudio for ARM an i'm using an USB->JTAG Interface from CrossConnect.
With a Demo-Board, i'll get a connection.
All JTAG-Signal's are ok. Reset is ok.

Thanks
Michael

Have you resistor between VSS and the RTCK pin?

Hey Albert,
I've a resistor between VSS and RTCK. And when I disable the "Identify
Target" in the IDE, it will be work, perhaps.

You mean JTAG works in this case?
Have you DBGSEL pin high too?

I don't know exactly, i think that the Compiler don't know the device.
