The GNU ARM Embedded Toolchain is wonderful, thank you so much for maintaining it!As both the host and target are fixed in the toolchain, would you consider adding insight or ddd or any graphical debugger to the standard release package? A graphical source-level debugger makes a huge difference and building one after-the-fact is difficult.
Please consider it and again many thanks for your generous contribution of easy-to-install tools to the ARM community!
Eclipse CDT is the closest solution I've found. It is free and it integrates reasonably well with OpenOCD and the GNU ARM Embedded Toolchain. I've documented the tools and setup here: http://www.dalbert.net/?p=544
