Feb.28 Debugger notes

[again: just dev notes]
Goal: Get at least 1 (gdb with ARM7) debugger working on laptop
Sideline: Flashing LMS


OpenOCD is what has been used. Looking for something easier to install and perhaps better

• OpenOCD
• used on lab PC ver.0.3 with patch (compiled) 
• However neither 0.3 with patch (both compiled and from lab PC) nor 0.4 (installed) work
• Possibly cygwin component not installed, but so far no clear documentation to check
• Have not found any .cfg command documentation.
• TCL in .cfg files may have changed between 0.3 and 0.4
• Segger
• Edu comes comes with debug software
• Understanding may help understand OpenOCD .cfg commands
• LOOKING AT DOCS
• http://www.segger.com/cms/j-trace-arm.html
• 1.3 J-Link / J-Trace models
• JLink.exe
• HW version info
