將我的草圖上傳到 esp32 時出錯

Question

當我嘗試將我的代碼上傳到我的 ESP32 時遇到問題。 確切的 model 是ESP-WROOM-32D , ESP32_DEVKit_V4

Output 是：

Sketch uses 1671989 bytes (85%) of program storage space. Maximum is 1966080 bytes.
Global variables use 57136 bytes (17%) of dynamic memory, leaving 270544 bytes for local variables. Maximum is 327680 bytes.

在串口中也有這個：

這是一遍又一遍地循環我不明白為什么會這樣，為什么我不能上傳我的草圖謝謝你的幫助！！！

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產生可能是您問題的答案：

從這個鏈接： https://github.com/espressif/esptool/issues/705

這清楚地表明問題出在有故障的開發套件上——特別是它們的 flash 芯片。 根據您的日志，在發生 flash 芯片讀/寫操作芯片之前，與 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

連接到 IOs 的任何其他硬件。

此警告與故障硬件直接相關。 嘗試運行 python -m esptool flash_id，此命令要求 ESP 詢問 flash 芯片並報告其制造商和設備編號。 如果失敗，則僅報告 0000s 或 ffffs。
