Cannot manage to setup and make working the remote debugging with Samsung Gear S3 Frontier

macOS 10.13.3 + Tizen Studio 2.1 + Samsung Gear S3 Frontier, native app. I am not able to get debugger in TS working with the remote device. This is what I got in console:

GNU gdb (GDB) 7.8.1

The Debug perspective shows up but the only active controls are Terminate and Disconnect, Step Into/Over are disabled.

Both the debugged app and gdb are hanging for longer than 10 minutes, I tried to enter some gdb commands but no response. After long timeout, the debugger stops at the breakpoint in the main(). Then I can step over, everything seems to be working, but when I resume, I got "Program terminated with signal SIGSEGV, Segmentation fault."

Is remote debugging supported with wearable native apps in general? What could I try to make it working? I suppose the gdb is not set correctly for the given device. Is any Samsung expert reading this thread, would be fine if we had got some support from them.

Thx for help in advance.

Hi,

The debugging environment uses GDB (GNU Debugger) for debugging with the emulator and a target device.
GDB can debug both locally and remotely. To ease the debugging process, you can set break points, step in,
step out, and step over break points, and watch variables to track the changes in their values in the Debug view.

Debugging native applications with Tizen Studio is same as with Eclipse CDT.

Check these link for more details about controls:

Check for "Table: Debug view control buttons".

Hope it will help you.

Thank you for your tips. I have read all the links you mentioned. Are you able to run debugger with gear watches? What model? What is your settings (Preferences-Debug)?

Re-install Tizen Studio. Check firewall setting and also check if any port blocking problem exists.
