LLVM (Rusts' backend) doesn't support the Xtensa instruction set, which makes this so complicated. The newer ESP32-C{3,6} instead use a RISC-V instruction set which is already supported by Rust, so its much easier to set up. So far I managed to get basic serial coms working, but am waiting for some HAL so I can build a blinky LED.
