Hi there,
I was following the esp-rs-book to get setup.
Compiling and flashing works with the regular esp-rs-hal and corresponding template.
However, I now need to use the esp-idf and am unable to compile it.
I have added the riscv32imac-unknown-none-elf target and installed these prerequisites: sudo pacman -S --needed gcc git make flex bison gperf python cmake ninja ccache dfu-util libusb.
Additionally, I installed the crates ldproxy, cargo-generate and cargo-espflash.
I then generated the template with cargo generate esp-rs/esp-idf-template cargo, no advanced options.
Trying to compile now results in errors regarding pointer types (*const i8 vs *const u8) (see end of post).
I compiled simply with cargo build and also with cargo +nightly build --target riscv32imac-esp-espidf. Results are identical. cargo clean did not help.
Some stats:
rust: v1.85.0-nightly
ESP_IDF_VERSION (from template): v5.2.2
Am I missing something here, or is this a bug?
Compiling std v0.0.0 (/home/joel/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/std)
