https://devzone.nordicsemi.com/f/nordic-q-a/1448/command-line-gdb-startup-gdbinitOle Morten has suggested using command-line GDB in a number of postings on this forum. Accordingly, I&#39;ve tried to do that but always getting the following error (&quot;Cannot find bounds of current function&quot;) on startup. $ arm-none-eabi-gdb.exe tmp_gcc_s110_xxaaen-USTelligent Community 13Mon, 27 Jan 2014 09:43:18 GMThttps://devzone.nordicsemi.com/thread/6473?ContentTypeID=1Mon, 27 Jan 2014 09:43:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:561854b2-ce6c-4612-8196-502a51fbca52Ole Morten<p>You can actually just remove everything from your.gdbinit except for target remote localhost:2331, as long as you make sure to configure the GDB server correctly when starting it (i.e. choose device, interface, speed).</p> <p>As for your exact problem, could it be that the chip is running the wrong code? Have you tried doing a load and a mon reset, and then continue? Also, are you sure you have the softdevice on the chip?</p> <p>Even though you&#39;re apparently on Windows, you may have use in taking a look at my <a href="https://github.com/hlnd/nrf51-pure-gcc-setup/">private GitHub repository here</a>, which I&#39;m using on Linux for personal development. This includes a target to start gdb, which as far as I&#39;ve seen works nicely, and in principle the same should be doable on Windows.</p><div style="clear:both;"></div>
