Proper setup for debugging Duet3

[LexJames]

@dc42 Sorry to ask you again about debugging the 6HC. I have a newer board v1.02 where SWD_EXT_RST is removed, so that can't be the problem. The fact that I don't see the 2 MHz SWCLK worries me. Is there anything I can verify (either hardware or software) to get a clue what is wrong? Thanks in advance.

[dc42]

@LexJames bear in mind that when debugging 6HC firmware on the version 1.02 board, you must use a Debug build because the release builds use the SWDIO and SWDCLK pins to drive LEDs.

@dc42 Thanks for this note, that was exactly one of my questions when I started this topic, but unfortunately I didn't specify that I also have hardware revision 1.02. I'll test with debug config next week

[LexJames]

@dc42 That explains a lot. Thanks!

[LexJames]

@Arplyu In case you want to verify your ICE, the ATMEL utility 'atprogram' has a nice selftest which allows you to test the wiring. You can run it from the command line.

After some struggles, I can finally debug the firmware in Eclipse with ATMEL-ICE. Below some hints for other developers who want to debug the RepRapFirmware on Duet3 6HC.
1 - Make sure to flash a debug version of the firmware before you even try to use ICE.
2 - Install 'OpenOCD' and configure it with 'duet3_openocd.cfg' from the RepRapFirmware repository.
3 - Replace the default debugger 'dbg.exe' with 'arm-none-eabi-gdb.exe'
4 - Make sure that the lock bits of the regions 0 to 40 are cleared. If you do a firmware upgrade those bits
will be set. Use Microchip Studio (+ATMEL-ICE) to clear those bits or flash your image with Microchip
Studio.
5 - Set the compiler optimization flag to -Os. (default is -Og).
Now it should work.

@LexJames I'm glad you got it working! Thanks for sharing your solution.

Sorry for getting back again to that topic. I finally found time to try compiling the debug version of MB6HC code. However, I'm getting errors if I try to compile for original 3.4.4 (my modified code is based on that, so I'd like to start from exactly this version):

Do you have any ideas what was wrong? Thank you

[dc42]

@Arplyu it looks to me that some of the files you are trying to compile are later than those used to build the 3.4.4 release, because we didn't add WiFi support to the 6HC until version 3.4.5.

[Arplyu]

@dc42 thank you for the reply. I use commits with tag "3.4.4" in all projects. Non-debug config from the same commits compiles without any problems, I used that as a start point for my modifications.

PS At the same time, checking out 3.4-dev branches at latest commits in all projects works fine - I managed to compile debug config and test the hardware, everything was ok.
