Breakpoints with Atmel ICE +VS+vMicro are ignored on setup area code

Hi I have update my VS +vMicro to 2020.518.1 and now the debugging with Atmel ICE present an new issue. When I place a breakpoints in setup area (I'm using a Arduino DUE board original) this breakpoint is ignored the program pass without stopped. If I place a breakpoints in to Loop this break point is correctly execute and the program is well stopped. I have tried with two separate breakpoints, one placed in to setup and one placed in loop. Same issue, the breakpoint in setup are code is ignored and the debug is sopped on second breakpoints on the loop. Before of last vMicro update this issue never see before. Do you have some idea about this? Smiley

If this is GDB debugging then will only do whatever it does. It might be that you can place a breakpoint in the main.cpp instead.

but no, he's never done anything like that. never happened before your update.  I always put breakpoints in the setup.

Again, you always need to post the information in yellow above. It is unclear if you are using gdb or serial debugging and unclear which port.

If using serial you would normally ensure the DTR on the serial monitor is enabled so that the mcu resets when the debugger starts. However the native usb ports can be a problem because they are not wired to the DTR therefore can not be reset automatically. In that case the mcu starts immediately after upload the setup() can not be tracked. Therefore you need to press the reset button on the board after the debug has started so that the setup() runs.

So I have not see that the upgrade affects any of this but you ar working with many combinatoions so you should be careful about what you think happens under the difference circumstances.

Hi, I have tried to press the mcu reset without effect, any breakpoints place on setup is always ignored. My configuration is: AtmelICE(uploader)  + AtmelICE(debug) GDB + vMicro on Arduino DUE original board.  In attach the debug log file.  Smiley

I'm seeing the same behavior after installing the latest update 19.0 for Visual Studio 2019. I've been using Visual Micro since it got started. I have 3 updated VS2019 computers and they all have the same issue. All 3 were stepping thru the Setup() code previously
Now when debugging with a Atmel ICE  hardware. 
I can set a breakpoint anywhere except the Setup() routine in Arduino Due, which gits ignored even though VS2019 sets it. The breakpoints in Setup() and any code it calls are ignored completely. The code continues to run in Setup() and can stop in Loop() breakpoints and any other code libraries. Please fix this ASAP I'm trying to debug an I2C peripheral on startup. Thanks Cry Cry

Thanks for the information.  On further investigation it appears as though the initCmd we use for the DUE/ICE is not being overridden with the "reset halt" additions when attaching the debugger.

We are looking internally at this as when attaching to a process this is not normally desired, but when running "start debugging" it is desirable (as they normally behave this way in VS when developing PC projects).

Until we have a fix for this available, the best solution is to Add a Custom Custom GDB Debugger JSON File to the project, and copy the JSON output from the MicroBuild into it from attaching the ICE.  This can then be modified on the end of the Debug Server Args command to become -c "init; reset halt" instead of just -c "init"

This ensures the MCU is reset when the debugger is attached, meaning setup code will be accessible easily.   

An alternative is to put a delay at the top of setup (e.g. 5s) and press reset before attaching the debugger.

Is there some documentation on how to do this? There are 32 projects in the solution. Or is it better to uninstall and re-install an earlier version. It appears to have happened when openocd-0.10.0.20200213 was installed, which was the last message before this. This is the first time setup code has been skipped over in debug, ever. I'll try the work around, but without an example my success will be questionable. Thanks

Well I tried first by putting breakpoint in main.cpp, nothing.
Saved the output from micro build debugger launch. Then added a Customer debugger file using the project add. Copied the json into the debugger file. -c \"init;reset halt\""

When ran debug the micro build output showed the same debug server args as before without the ;reset halt as -c init
-c \"source [find target/at91sam3ax_8x.cfg]\" -c \"init\"", that didn't work either. 

Tried the 5000 millisec delay with reset and debugger couldn't attach.

Renamed debuger custom file with .txt added to upload

Rolling back to an earlier version is possible but not recommended, as OpenOCD has had a number of improvements which were added over the previous year to that project.  It would also mean staying on an older version of Visual Micro as we only support the latest version of OpenOCD in our latest software.

There is documentation on the JSON file additions and changes on the Debugging Using Custom Hardware page.

When using the JSON, the debugger needs to be changed to "Manual / Custom" to take effect - apologies for missing this step.

Does changing the Debugger to Manual / Custom with the JSON File in place improve things?

There is a new release available from the below forum page (20.06.18.5), which should resolve this problem.

Previous Releases, New Releases and Notifications

When you now run "Debug > Start Debugging" it will perform the upload, and ensure the board is reset as the debugger automatically attaches, so you can debug setup().

If you run "Debug > Attach to Process" it won't reset the board on attach, so you can inspect the current situation.
