Currently only Cortex M is supported, but PR's are welcome!
There are likely many bugs in the tracing of variables. If you notice anything, please make a PR.
It would help if you can include the output of readelf <your_elf_file> --debug-dump in the issue (as a gist link).
For me to be fully able to reproduce the tracing, I will also need your elf file.
Both the debug dump and elf file can be sensitive for IP reasons. So if you can't include it in the issue, I can understand.
The output of the trace can look like this (with some spammy variables left out):
