+'''Using gdb'''
+
+It is possible to deploy an application and launch it in debugging mode on the BB10 device.
+
+First source your shell envrionment from the BB10 NDK environment script:
+{{{
+source bbndk-env.sh
+}}}
+Then deploy the application with debugging enabled:
+{{{
+blackberry-deploy -installApp -launchApp -debugNative <device ip> -password <device password> -package HelloWorld.bar 
+}}}
+In the ourput of this command you should get something like this at the end:
+{{{
+result::32395406
+}}}
+The number is the application PID you will use for debugging it with gdb.
+
+Next, start the BB10 NDK gdb:
+{{{
+ntoarm-gdb
+}}}
+From inside the gdb shell:
+{{{
+echo target qnx <device ip>:8000
+attach <PID>
+}}}
+
+The result:
+
+{{{
+(gdb) attach 32395406
+Attaching to pid 32395406
+"/usr/bin/python3.2": not in executable format: File format not recognized
+(gdb) run
+../../gdb/thread.c:72: internal-error: inferior_thread: Assertion `tp' failed.
+A problem internal to GDB has been detected,
+further debugging may prove unreliable.
+Quit this debugging session? (y or n) n
+../../gdb/thread.c:72: internal-error: inferior_thread: Assertion `tp' failed.
+A problem internal to GDB has been detected,
+further debugging may prove unreliable.
+Create a core file of GDB? (y or n) y
+}}}
+
+So its not really that usable for debugging Python applications but probably could be somehow fixed to provide some meaningful output.
