Debugging Session Errors on Breakpoint #36

Closed curiousmuch closed 2 years ago

curiousmuch commented 2 years ago

Hello!

The first break point I hit debugging my application results in a number of errors in the debugging log. I'm using the latest version probe-rs w/ the latest release version of the vscode extension.

Example 2:

[2022-07-03T18:26:42Z ERROR probe_rs::debug::debug_info] Failed to read referenced variable address from memory location 0x1CCE580E : An error with the usage of the probe occurred.

I'm clueless where this is suppose to be lol.

Thanks. It definitely seems like there is something funky with the memory addresses. These are calculated using the debug info (DWARF) generated as part of creating the binary, and it is quite possible that there is an issue with the logic.

Is this just the standard 'blinky' example? Have you made any changes to the config files? Can you give me some info on where you've set the breakpoint in the source file?

I don't get these errors, so to reproduce/fix I will need a little more info please.

noppej commented 2 years ago

@curiousmuch I've done some work against breakpoints and variable handling that is now checked into the 'master' branch. Any chance you can retest, and/or answer some of the above questions?

noppej commented 2 years ago

Closing until further information/testing by OP.
