Rust + Embedded + gdbserver + JLink
I am trying to put together a complex use case, but it looks like things are *almost* there. But I need a little bit of help, since I am not so familiar with CLion.
I am trying to set up CLion to do development wth Rust for an embedded target. Getting debugging working would make this a complete environment.
I have tried to create an "Embedded GDB Server" configuration, but unfortuantely I am left with a selection that says: "Nothing to run on".
So far, I have installed the Rust and Cargo plugins. Cargo plugin works fine for creating build configs, and by using the .cargo/config, I can target my embedded target.
For the debugging part, I am trying to use a J-Link debugger, since they are the best, and they provide a gdbserver.
gdbserver + arm-none-eabi-gdb definitely works from the command line, and I can load, run, and debug the ELF. Now it is just a matter of getting CLion to work with that.
Attached is a screenshot of how I have set up the configuration. Any clues as to why this results in something that is not launchable?

I think it's not possible yet to configure pure Rust(=non-CMake) project + embedded debugger.
Nevertheless, we have a couple of working examples Rust+C+CMake+embedded examples.
You may have a look at those:

https://github.com/elmot/f3-rust/blob/master/CMakeLists.txt#L43-L65
I'd also highly recommend you to add -LocalhostOnly -nogui -singlerun keys to gdbserver parameters.
Ilia Motornyi, is this feature being worked on?
Well, we're getting closer to that, just because of various code changes and refactorings, but no actual schedule. I am afraid CMake+cargo(xcargo) is still the only option.
If you wanna embedded rust rushed, please file a ticket at https://youtrack.jetbrains.com/newIssue?project=CPP&c=Subsystem%20Embedded
People can vote there, and if the ticket gets enough of votes, we'll prioritize it.
Perfect, I've filed a ticket. Thanks!
Hi DDrost, do you have a link to the ticket you created? I'd like to upvote it but can't find it...
Here's the ticket:
https://youtrack.jetbrains.com/issue/CPP-18738
I should follow-up and see if they are unblocked on getting the embedded example up and running.
Awesome thanks Andrew.
I've made a CMake module to create CMake targets for rust following Ilia Motornyi examples. It may be helpful to others until native support lands in CLion.
