Can you replicate the examples on Windows?

Let us know if you had to significantly deviate from the instructions! (Other than using different built-in commands if you were using cmd instead of bash).

I have an issue with the windows version of Qemu 3.0.0 but in an Ubuntu VM I could run the exact same binary fine with Qemu 2.5.0. I haven't tried that version on windows yet.

After forwarding the gdb port on the VM back to windows, I could get arm-none-eabi-gdb to work but had issues with the windows version of LLDB.

All the tools work with the exception of debugging as mentioned above.
LLDB Version used and output when trying to connect to Qemu:

λ lldb --version
lldb version 6.0.1 
λ lldb target\thumbv7m-none-eabi\debug\app
(lldb) target create "target\\thumbv7m-none-eabi\\debug\\app"

(lldb) gdb-remote 3333

Qemu used:

Using arm-eabi-gdb downloaded from here: http://gnutoolchains.com/arm-eabi/ debugging is working as shown in the examples.

@nateglims @LokiFaun Thanks a lot for testing this!

Since you (and some macOS users) are having issues with LLDB I'll change the text to recommend and use GDB.

Also, could you tell me from where you installed qemu-system-arm? I'd like to add a small setup section similar to this one but for Windows.

[nateglims]

This package includes QEMU and qemu-system-arm I found it because it was linked from the qemu website

[LokiFaun]

I installed from the same link @nateglims mentioned.
