I am brand new to ARM development (but not to embedded programming). I
have installed the WinARM tools on my Windows XP machine. I have an OKI
AME-51 evaluation kit, which has an evaluation board with an OKI
ML67Q4051 processor, and a J-Link USB/JTAG interface box. I have
successfully compiled and linked a small project using WinARM with
Programmers Notebook. Output when doing a Make All is as follows:

My problem is in trying to use Insight to download this code into RAM
for debugging. I do the following:

I launch JLinkGDBServer.exe. I launch arm-elf-insight.exe. In
File->Target Settings I set Target to GDBserver/TCP and Port to 2331. I
check Set breakpoint at main and at exit, and check Display Download
Dialog. I use File->Open to open  TestWinarm.elf. Source code for main.c
is displayed. I select Run->Connect to target. I see a Successfully
connected dialog box. I select Run->Download. I do not see a download
dialog box, but I see the following error message in the status bar at
the bottom of Insight:

DOWNLOAD FAILED. Invalid download offset: and.

Help! What am I doing wrong? Will Insight work with the IAR/Segger
J-Link USB/JTAG interface? I have the option switches on my evaluation
board set to map the external RAM (1 MBytes) starting at address 0. I
have tried pressing (or not pressing) the processor hardware reset
pushbutton on the board before downloading. I cannot seem to get my file
loaded into RAM. It works when I use the IAR software tools that came
with my evaluation board, but I really don't want to have to spend lots
of $$$ for the full software tools for my rather large project. Insight
seems to be communicating with the JLinkGDBServer. I can use
View->Memory to view and modify memory starting at 0. But I can't seem
to download my program for debugging. What am I doing wrong?
