当我尝试将代码上传到ESP32时，我遇到了一个问题。确切型号为esp - room - 32d,ESP32_DEVKit_V4
输出为:

这是一次又一次的循环我不明白为什么会这样，为什么我不能上传我的素描谢谢你的帮助!!
快速搜索您收到的警告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，您的问题的答案可能是:

这是一个明确的指示，问题是有缺陷的开发工具包-特别是闪存芯片。根据你的日志，通讯在闪存芯片读取/写入之前，ESP工作良好操作芯片发生
WARNING: Failed to communicate with the flash chip, read/write operations will fail. Try checking the chip connections or removing任何其他连接到IOs的硬件。
此警告与硬件故障直接相关。试着运行python-m esptool flash_id，该命令要求ESP查询flash芯片并报告其制造商和设备号。如果这如果失败，则只报告0000s或ffff。
