This repository hosts the wireless-driver's binaries and low-level bindings.

If you are looking for esp-wifi see esp-radio in esp-hal

The headers and libraries are prepared in esp-wireless-drivers-3rdparty.

Depending on the lld version used by the toolchain you might see linker errors like this after copying the libs:

rust-lld: error: relocation refers to a symbol in a discarded section: .L0 
            >>> defined in /Users/espressif/action-runner/esp-rs/_work/esp-hal/esp-hal/target/riscv32imac-unknown-none-elf/debug/build/esp-wifi-sys-esp32c61-e592915ee1a41dea/out/libphy.a(phy_api.o)
            >>> referenced by phy_api.o:(.eh_frame+0x12d4) in archive /Users/espressif/action-runner/esp-rs/_work/esp-hal/esp-hal/target/riscv32imac-unknown-none-elf/debug/build/esp-wifi-sys-esp32c61-e592915ee1a41dea/out/libphy.a

You can strip the .eh_frame segment from these binaries like this, to make it work: riscv32-esp-elf-objcopy --remove-section=.eh_frame esp-wifi-sys-esp32c61/libs/libphy.a
