Problems connecting to server pool

[latemine]

Hello, I'm having issues getting the python script to run. Any help would be greatly appreciated.

Command: python3 .\fpgaminer.py -i python -o stratum+tcp://stratum.slushpool.com:3333 -u usernameC -p password

Logs: [2021-12-14 00:43:58] [INFO] Starting server on stratum.slushpool.com:3333 [2021-12-14 00:44:27] [ERROR] ERROR: generator raised StopIteration [2021-12-14 00:44:31] [ERROR] ERROR: generator raised StopIteration [2021-12-14 00:44:35] [INFO] Found share: ['username', '2db89b7a34', '00000000', '61b83d50', '000006e9'] [2021-12-14 00:44:35] [INFO] Found share: ['username', '2db89b7a34', '00000000', '61b83d50', '0000070d'] [2021-12-14 00:44:39] [ERROR] ERROR: generator raised StopIteration [2021-12-14 00:44:39] [INFO] Share - Invalid Exception in thread Thread-1: Traceback (most recent call last): File "C:\Users\username\Desktop\Python_Projects\fpgaminer\fpgaminer.py", line 446, in _handle_incoming_rpc self.handle_reply(request = request, reply = reply) File "C:\Users\username\Desktop\Python_Projects\fpgaminer\fpgaminer.py", line 567, in handle_reply raise self.MinerWarning('Failed to accept submit', reply, request) main.Miner.MinerWarning: Mining Sate Error: Failed to accept submit

It looks like you are running on a Windows machine and using a different Python version. Did you already modify the script to remove the Pynq modules? I would probably try to create a virtual environment and use Python 3.6.5

[latemine]

FPGA:

• I re-coded the interface to user-intfc <-> uart <-> ftdi
• compiled targeting Virtex 7 @160MHz
• 64digesters
• possible to fit 4-5 instances of the sha256 if I spent more time.

Python:

• Python versions 3.7 give me errors and I moved to 3.6
• I remove pynq and added pyserial to communicate (very slow)
• connected to nicehash and slushpool but the miner doesnt register
• only achieving ~5MHash
• python script seems to reset in the middle of python function "miner" I'm wondering if that's due to the pool or some timeout I'm missing

Summary:

• sha256 could achieve ~200MHz with a little work
• python is a pain and I'm not confident it's actually communicating properly with pool
• all in all it's decent code, could be optomized a bit and maybe hand placed to squeak out a few MHz

You can try running the python script with the -P and -d flags to get some extra debug output.

[latemine]

I added the -P and -d flags and am running the"Python" implementation and I'm not sure it's working quite right. The miner never shows up as connected on slushpool and I get an error message when trying to use nicehash. It looks like it has to do with the "incoming_rpc" based on the exception error. Have you ever seen anything like this before.

Thanks,

I have not seen this error before, but I think the problem is that a case for what to do for the "client.reconnect" method is not defined in the handle_reply() function in the python script. Does this error occur on slushpool too?

[latemine]

Yes, if you run in -python mode it will connect to either pool for a short period of time but eventually error out due to the highlighted portion of the code.

def_handle_incoming_rpc(self): try: request = None with self._lock: if 'id' in reply and reply['id'] in self._requests: request = self._requests[reply['id']] self.handle_reply(request = request, reply = reply) except self.RequestReplyWarning as e: output = e.message if e.request: output += '\n ' + e.request output += '\n ' + e.reply log(output, LEVEL_ERROR)

[rkharris12]

I think that confirms my suspicion about a case for what to do for the "client.reconnect" method not being defined in the handle_reply() function in the python script. The script tries to execute handle_reply() but fails and issues a warning that is logged in the except block.

Does this happen with just the python implementation, or the other implementations too? I suspect since the hashrate is so low the server thinks something is wrong and tries to reconnect.

If it does happen for the other implementations, I might look into adding a case for handling a client.reconnect request.
