As concerns the actual bitcoin mining client on ESP32-S3 , Has anyone attempted to port the cgminer 4.12 code  to rust so as to fit ESP32-S3 constraints . The Open Source Braiins OS is written in Rust supports using ARM Cortex CPU-based control boards like BeagleBone and has the drivers for all Bitamin S9, S17 & S19 Series Chips  . i don't see it supporting ESP32-S3 which has a dual-core XTensa LX7.

Braiins OS requires at least 200 MB of storage ( 105 MB used for OS ) and i guess less than 512MB of RAM to run. All this are constraints for ESP32-S3 , Even if we strip down the code and rewrite it  or use a different base as reference we will still need to have a fully fledged bitcoin mining client to avoid a lot of frustrations. I haven't come across any reference code online that has used ESP32-S3 / ESP32-WROVER (N16R8)  with Rust as a control board for antminer BM13xx chips.

Any Ideas ?  Skot has a good start ESP32-Miner repo created.
