Is the Repo in Sync with Embedded Hal and ESPUP? Linker Problem

[Token-Thinker]

Hey All,

I didn't want to put this into an issue, because it could be user error but I wanted if anyone else was having an Linker problems with esp_wifi only for example below:

xtensa-esp32-none-elf/debug/deps/libesp_wifi-9abed293f48fedbc.rlib(esp_wifi-9abed293f48fedbc.esp_wifi.2f9ebf688567966b-cgu.1.rcgu.o):(.literal.usleep+0x4): undefined reference to `esp_rom_delay_us'

Could you tell us more about your setup please? Versions of crates, tools, environment etc.

As @MabezDev already said we need a bit more information but one possible reason could that the ROM functions are not linked: https://github.com/esp-rs/esp-wifi/blob/main/esp-wifi/README.md#link-configuration
