i have looked at running bare-metal Linux 5.0 kernel and cgminer 4.12 on ESP32-C3-DevkitC-02 but can't seem to find a better clean way to do it. Everything seems so complex with tons of bugs to accomplish. The best way is always the simplest way.

Just to run bare-metal Linux 5.0 kernel on ESP32-C3 you need to add external memory using the SPI at least  8 MB (preferably 16 MB )  PSRAM plus 2 or 4 MB Flash and then connect a MicroSD for storage (32 or 64 GB ). Should we rethink using ESP32-C3-DevKitC-02 ? and try something else ? Not sure what it might be.

How about using  -- The Raspberry Pi Zero 2 W  for US $15-- it has everything we need with 40-pin breakout with all the pins we need and might act as drop in replacement for ESP32-C3-DevkitC-02. it can run 32bit & 64Bit ubuntu 20.04, 21.04 and so on. All we need is to add cgminer 4.12 (Kanoi version ) . Any ideas or experience about this ? i think Nonce did something similar .


Porting Cgminer 4.12 drivers for Gekko Compac-F to ESP32 is something we really need !!! .

So has somebody here actually done it and built this miner and can tell what is the efficiency in comparison to simply using a complete S9? I would be interested in pulling apart an S9 to do the project, but so far I’m not shure if it is really worth it.
