Starting difficulty is set by the pool, the miner can suggest one, but the pool does not have to follow it. Setting the difficulty to "1" will just overload your local pool with worthless shares and traffic over your network. |

That is exactly what I want, though. I've configured my pool to ignore any other block solution once it finds one. Have I understood right that it's the "256" number that I need to change? (Into 16 for example.) |

You will not be able to solve a block with a difficulty of "1" for BTC, you will be just sending too many shares to the pool (I assume your running your own local node here to mine to). Research Stratum with VARDIFF to understand how it all works. |

Yes, but I'm not mining bitcoin. It's a test network. |

You need to configure the stratum your mining too for that. "mindiff": 1, |

Configure it where? I'm told that there's a default, pre-configured, hardcoded mindiff that the Bitaxe will send to my ckpool, and I suppose I need to change that from the firmware code. I'm not sure if you're asking me to change that, or to change the configuration in my ckpool. I've tried the latter, and the Bitaxe still sends block solutions with difficulty > 256. |

Post a screenshot of the logs from the miner here, lets see whats there for this. |

Here's some logs I just got from it. Note that this is not mining on the aforementioned ckpool, but on some other of mine (for a different purpose). As you can see, it keeps sending solutions with difficulty > 256, which gives me the impression it's not a mining pool thing; it is internally configured to send solutions with a minimum difficulty. |

I see nothing wrong here, it's working as expected. Testnet example where the network difficulty of the coin = 1 
Stratum locked to 1 in the example. |

esp-miner hard codes the ASIC chip difficulty to 256. You'll have to change that in the init code for the ASIC you are using. This is going to generate a TON of nonces, probably swamping esp-miner. You might have better luck modifying cpu miner software to do this test. |

Yup, your going to need to use less powerful hardware for this. |

It's risky, but I like it. Hopefully, it doesn't get damaged. Thanks @skot, I just needed the confirmation that it's that value. I'll change it, and let you know. |

Guys, I'm getting the following error: My bitaxe is the 601 one. The code that I compiled with the ESP-IDF toolchain is the most recent one from: https://github.com/bitaxeorg/ESP-Miner/. What happened? I only changed 256 to 32. |

The solution to the problem above is the following. Instead of using the following commands to build and flash: I did this: And everything went flawlessly. |

I'm in a situation where I need Bitaxe's starting difficulty to be 1, because I need to solve a block with difficulty=1 and send it immediately (with the least delay possible) to my ckpool. Is it possible to configure the firmware to do that? I think there's a hardcoded minimum (256), because I've noticed my ckpool displaying solutions that are greater than 256. I was wondering, perhaps it's these four lines?
By "starting difficulty", I mean the difficulty that is minimum for the block solutions to be delivered to ckpool. As far as I know, all ASICs have a hardcoded minimum, like 65k, because otherwise it'd overwhelm the CPU.
