将我的草图上传到 esp32 时出错

Question

当我尝试将我的代码上传到我的 ESP32 时遇到问题。 确切的 model 是ESP-WROOM-32D , ESP32_DEVKit_V4

Output 是：

这是一遍又一遍地循环我不明白为什么会这样，为什么我不能上传我的草图谢谢你的帮助！！！

快速搜索您收到的WARNING: Failed to communicate with the flash chip, read/write operations will fail. Try checking the chip connections or removing any other hardware connected to IOs WARNING: Failed to communicate with the flash chip, read/write operations will fail. Try checking the chip connections or removing any other hardware connected to IOs产生可能是您问题的答案：

从这个链接： https://github.com/espressif/esptool/issues/705

这清楚地表明问题出在有故障的开发套件上——特别是它们的 flash 芯片。 根据您的日志，在发生 flash 芯片读/写操作芯片之前，与 ESP 的通信工作正常。

 WARNING: Failed to communicate with the flash chip, read/write operations will fail. Try checking the chip connections or removing

连接到 IOs 的任何其他硬件。

此警告与故障硬件直接相关。 尝试运行 python -m esptool flash_id，此命令要求 ESP 询问 flash 芯片并报告其制造商和设备编号。 如果失败，则仅报告 0000s 或 ffffs。
