Minimal no_std embassy main() on esp32s3: "abort() was called at PC 0x403ceab9"

[brainstorm]

I guess this abort() comes from the esp-backtrace bultin panic handler (which aborts?) and I'm surely not handling it right?

Here's the complete code, output and some more context: https://github.com/brainstorm/esp-rs-embassy-abort-repro

I had a look at your repo and the problem is it doesn't produce any code because it doesn't include the linker script

You would either need to add "-C", "link-arg=-Tlinkall.x", to .cargo/config.tom in [build]/rustflags or use a build.rs like the template does: https://github.com/esp-rs/esp-template/blob/c5064f03b5cf5a1f8a2682a308aed5f381770931/build.rs#L1-L2

Indeed, my apologies, don't know why I missed that trivial linker configuration bit in the template :/
