Great advice. Coding an ESP Miner to test it correctly, is a pain.

that's a lot of grunt work to be done.

For sure; it was never going to be easy!

But I'm sure we can get it done as a group. I will have lots more free time pretty soon. All the components are already here, except BM1397. I had troubles finding them at a reasonable price and shipping speed and now I have none. Roll Eyes

The biggest problem i have encountered is the support and community for xtensa-esp32s3 using rust is minimal or non-existent at best. i have tested some simple ESP miner code on my ESP32-S3-WROOM-2-N32R8V Dev board that i have and it runs fast but that is without it communicating or mining on BM1397 chips. Next step will be to try adapt this minimal testing code to communicate and mine on BM1397 chips and use it on the onboard ESP32-S3-WROOM-1-N16R8V on my ESP mining board.

I think I'll start with the Stratum connection and that side of things (using regular ESP-IDF), since again: I don't have ASIC chips yet. Undecided

Hey !

I can send you a lot of old S9 / S9k hashboard if needed !

For free, I juste don't want to pay the shipping but I don't care about the boards

Hey there, thanks for the offer! I believe NebulaMiner wants to / started reverse engineering ASIC communication / protocol of Bitmain S17.
The S9 have older chips, but since protocols may stay the same between miner generations, it could be interesting for him to look at the S9 boards.
