I was not able to get xtensa to work but newer ESP32 devices use the RISC-V which has good LLVM support. Here are some experiments I did:

The ESP32 family of microcontrollers are quite popular because they quite inexpensive and jet rather powerful (dual core processor, WiFi and Bluetooth). Once you have a Julia build with RISC-V enabled as LLVM target, GPUCompiler.jl can generate an object file with the compiled Julia code. I wrapped some functions from the Arduino API to ma…
