HELP! I am at the end of my rope. I have been trying for over a week to use the WinARM tools to develop and debug a simple LED-blinking application for the OKI ML67Q4051 ARM7 processor. I have an OKI AME-51 evaluation board. I have installed all the WinARM tools, including programmers notepad, arm-elf-gcc, arm-elf-gdb and arm-elf-insight. I can create a project, compile, link, and get an elf file. Everything looks good. The map file says everything is at the correct addresses. Then I try to debug using insight, and nothing works. I built my own wiggler clone. It works. I can actually load and debug my application using the IAR Embedded Workbench evaluation software that came with my evaluation board (using my wiggler). But when I try to debug using insight, I have trouble. I can launch openocd-pp. I can launch insight, and connect to the target at localhost:3333. I can even use file->open to open my elf file, and insight shown me the source file(s). But any attempt to download the file to the processor, or to run the program, is met with total failure. I cannot seem to get the code to download into the RAM on the demo board. I have mapped the external 1 MByte RAM to address 0 and linked the program to address 0. I have also tried linking to address 0x10000000 and loading the application into the 16 KBytes of on-chip RAM. No luck either way. When I Run->Download, insight gives me the error message "DOWNLOAD FAILED: Invalid download offset: and." in the status bar. I am about ready to shell out $5000 for the full blown IAR Embedded Workbench software. I cannot even find any documentation for insight. Clicking on Help->Help Topics gives me a dialog box that says "Error: invalid command name "ide_shell_execute"". With no documentation or help, what can I do? I would appreciate a response from ANYONE who knows how to use insight.

I have made some progress on this problem. See my comments below. Patrick Deflandre wrote: >> HELP!

After banging my head against the wall a few days I discovered something. I had to open a console window in insight and give it the following commands: file myproject.elf mem 0 0xfffff rw target remote localhost:3333 load The key seemed to be the "mem" command to tell GDB that I had read/write memory available from 0 to 0xfffff. Without the "mem" command the "load" would fail. I am now trying to automate the process with a startup command script file for insight. I can also use the jlinkgdbserver (instead of openocd) and use the Jlink USB JTAG adapter (at port 2331) instead of the wiggler. This is good, since one of my computers has no LPT port. Keith Rubow
