Crossworks 3.7 consistently crashing when debugging

I am using Crossworks v3.7 to do some development on an Cortex-M4.

The IDE is crashing consistently (like after a couple of steps) when debugging the code on the board.

The code itself is not causing any hard faults/bus faults etc, it runs fine when released, but when stepping through line by line the IDE will just die.

Can I get some reports for someone to look into this?

  Is the IDE also crashing with the most reasoned Version of Crossworks?

  Could be unhandled dwarf debugging data - if you zip and attach the .elf file I'll have a look

  Markus - Yes I've tried the trial version of v4 and it also crashes in this.

  Michael - Not too familiar with how the SWD data is parsed and what is transmitted in this protocol - so I will ZIP and example elf when I'm at my dev machine for you to take a look - many thanks for your help.

  I am able to debug by using F9 to set breakpoints and F5 until those are reached, when stepping over or out of lines however it will just collapse with no warning, although it does this most often when stepping over a curly brace, indicating stepping out of a method, or to the start of a for/while loop.

  The dwarf data is the stuff the compiler generates that the debugger has to interpret - I suspect it's a problem in this area.

  Hi Michael, You can find the ELF here: https://drive.google.com/file/d/1JeSQ5tCdnjigezHgG114Rkjb5B5UVkBK/view?usp=sharing

  Thanks for any assistance.

  Hi Michael - I am using the XMC4300 from Infineon on their Relax development kit board. Crossworks has a sample solution in it's templates for this particular chip/dev board.

  Cheers,
  James

  I did have this problem with a chip from Nordic Semiconductors nRF52840 (also Cortex-M4), I believe earlier this year, but it wasn't as critical there as I was only testing an issue with the code as opposed to writing a new application.

  I can download and step etc at assembly code level - do you have a watch window open - if so what are you watching?
