Hi all,
I have been stuck trying to debug the example project for a couple of days now and could not find the answer through searching. Here are my problems.
Background:
I am using Eclipse Luna on Mac and on pc. SDK version 6, compiler 4.8.4, S110 version 7, JLink version 4.9
I have followed this guide: devzone.nordicsemi.com/.../ it is very helpful. However I am stuck at debugging stage. Everything works fine compiles and was able to flash the generated files on the chip with nrfgo fine. I have already flash S110 softdevice on there.
Problem:
I am having a hard time starting the debug process. My debug configuration is the default for the Jlink GDB with first breakpoint being set in main.
When i started the debug configuration everything loads starts fine no error and the current debug pointer is set at the timer_init() which is the first function of the main().
The only problem with this is that Eclipse is not giving me option to run the program. The buttons for the step over, step into, run, reset, or terminate on the tool bar is not available to select. The Run option from the menu are also not available.
There was a point in time when I was trying to make this work the buttons showed up but then the program keep on throwing out hard fault and does nothing else.
I have no clue of what to do next. Any help pointing me in the right direction would be appreciated.
I have include the JLinkGDBServer log
