ARM development environment Modified Use - preparation Install the development environment Create an empty project directory no spaces in the pathname! Unzip a project zip file into that directory Connect the board (USB + parallel) Open the project (.ppr) file to start the environment
ARM development environment Modified Use – build Build the project
ARM development environment Modified Use – start JTAG debugger Start the debugger
ARM development environment Modified Use – configure the debugger interface If this screen appears: enter the settings as shown
ARM development environment Modified Use – (debugger) - download Start downloading your code
ARM development environment Modified Use – (debugger) - start your program Run your code
ARM development environment Modified Use – debugger - stepping Single step, step into functions Single step, step over functions
ARM development environment Modified Use – debugger - stepping Run up to end of current function
ARM development environment Modified Use – debugger - stop Stop your code, then close the debugger
ARM development environment Modified troubleshooting If you see this you must set the MAC_MOT driver to auto-start: control panel > system > hardware > device manager (select view > show hidden devices) > non plug-and-pray devices > MAC_MOT > driver status = started, type = automatic
ARM development environment Modified Installing the development environment installs the MAC_MOT driver. If it somehow disappears from your PC you could install the Macraigor OCD commander. troubleshooting
ARM development environment Modified If you try to build while the debugger is still active, you will get this error because the debugger has locked the executable file so the compiler can not write to it. troubleshooting
ARM development environment Modified If nothing else seems to help: disconnect the PCB, reset your PC, and start all over. Don’t use an unpowered USB HUB between your PC and the ARM board. If possible, connect directly to your PC. troubleshooting
