I have upgrade grin-miner to the lasted

Hi @Jaschenn. Which plugin are you using? You must use cuckarood29. Cuckaroo29 is no longer used by Grin.

[Jaschenn]

the config are as follows:

[[mining.miner_plugin_config]]
plugin_name = "cuckaroo_cpu_avx2_29"
[mining.miner_plugin_config.parameters]
nthreads = 4

Maybe this is the reason. And where can i get cuckarood29?

[quentinlesceller]

Take a look at here https://github.com/mimblewimble/grin-miner/blob/master/grin-miner.toml#L107. This is where you can enable cuckarood29 plugin. There is no CPU equivalent right now, only Nvidia miner. I'm going to close this issue since it's not a bug or a requested feature. Thanks! You can continue to comment here if you have any question.
