JTAG Debugger Problem
2004-11-04 by Joe
New user question, just trying to get started with the LPC2129 ARM7. I just ordered and received 2 Olimex LPC-H2129 boards and an ARM-JTAG Debugger. I downloaded the Philips LPC2000 Flash Utility V2.2.0 and with the BSL jumper in place I can talk to the boards, so I know that they are alive. I downloaded the Macraiger Systems OCD Commander software Ver 2.3.9 The BSL jumper is removed, the DBG and JRST jumpers are installed, and the board is reset. The lpt1: port is set for EPP mode. I start the OCD Commander software and set Target Processor = ARM / ARM7xxx OCD Interface Device = Wiggler Speed = 8 ( I have tried 1,5,8 I believe 8 is slowest) I tried this with both LPC2129 boards. I tried this on a Dell OptiPlex GX115 running XP/Pro. I tried this on a Compaq Armada 100s running Win98 SE. The response always received is "Error Response from INITIALIZE: 0x03 cable disconnected (03:10)" Am I doing something stupid????? Can I tell with a scope on the JTAG lines if the debugger is working???? What else can I try????
