New discovery: Adding a delay can make it last a bit longer, but it still crashes eventually. |

Thanks for the report and the reproduction script, that helps a lot! Oddly though, my build from the latest on that PR fails much worse than yours.... running the steps of your script manually, my C6 seems to just hard-reset as soon as I try to connect wifi at all - regardless of whether a valid ssid/pass is used at all: I don't even get a guru meditation to track down... |

Thank you for the guidance, I have finally found the community. Currently, I am continuously increasing the delay to test stability. As shown in the figure above, it took more than four million sends at a delay of 0.3ms before it crashed. However, there is an obvious pattern that every crash stops at the pointer 0x40825dd0. This led me to suspect a hardware issue, so I plan to buy several development boards to test. This is all I can do at the moment, as I haven’t had time to learn more about the deeper levels of development… If there is anything you need me to assist with, such as testing the latest firmware, etc., please let me know, and I will actively cooperate with you:) By the way, the development board I am using is this one, for your reference: github.com/wuxx/nanoESP32-S3 |

另外还有一个坑，由于新买的路由器是白色，我放的位置又挨着窗户，为了不让它的外壳弄脏我把内包装的塑料袋子套上了，，，这就导致了它难以散热，导致速率变得比实际低了许多。当我摘了袋子之后速率肉眼可见的涨了一截。 |

Hi @freejygithub , Where did you find the MicroPython firmware for the ESP32C6 online? |

I've just tested my PR for the C6 with IDF v5.2.2 and it no longer crashes for me where it was an immediate crash 100% of the time on v5.2.1 ! |

Great, all set. Thank you. |

It seems like I’ve successfully compiled and burned the firmware. Here’s the output from Thonny, could you please help me check if it’s your latest version? |

Then I conducted an ADC test. The ESP32C6 has a total of 7 ADC pins, which are IO0 Additionally, I conducted an extreme transmission test with Wi-Fi 6, and it still reported an error and rebooted. |

After testing, only IO0-4 can read ADC values normally. Could it be that IO5 and IO6 are occupied by Wi-Fi? |

That appears to be an older version of my PR from a week or two ago. Since then those list two ADC pin definitions have been fixed (thanks to review by @projectgus ) Pulling the latest version of the PR should fix that. Can you give more details about your wifi test? Is it definitely compiled with IDF 5.2.2 ? |

Recently, I found a MicroPython firmware for the ESP32C6 online, and luckily, I have a development board to try it out. It worked, but I encountered a crash error while testing the WiFi to send data packets. Here is the error I encountered:
[Error message and code provided]
I don’t know which repository this firmware was compiled from; I only know that this bug is easily reproducible and will cause a crash and reboot after running for a few dozen seconds.
Please help me take a look at what might be going on.
