Hi,

While running the next line, from the commit 75b4e4f406c91d8b5e444343b42518b3a176dbdb:

cargo +esp espflash --release --example blinky --target "xtensa-esp32-espidf" --monitor

I get the following error in the library esp-idf-sys v0.31.6:

  error: unknown target triple 'xtensa', please use -triple or -arch
  thread 'main' panicked at 'libclang error; possible causes include:
  - Invalid flag syntax
  - Unrecognized flags
  - Invalid flag arguments

Same as esp-rs/esp-idf-template#47 or esp-rs/esp-idf-template#49.
Basically the xtensa chips need a custom libclang so that the xtensa target is supported.

Ok, solved, so if happen to someone else:

rustup update
git clone git@github.com:esp-rs/rust-build.git
chmod +x install-rust-toolchain.sh
./install-rust-toolchain.sh -i reinstall <-- this can probably fail the first time, so then
softwareupdate --all --install --force
./install-rust-toolchain.sh -i reinstall

Then try again the build.

I think the issue is that, for some weird reason because I installed this like 1 month ago, it was targeting "--rust-target", "1.47",
