[填坑]esp32烧写报错 Detected overlap at address: 0x8000

问题描述

更新项目的 esp_idf 框架，从 release/v3.3 46b12 到 release/v3.3 2befd ，编译无错误，但是在烧写时出现以下错误 Detected overlap at address 。

Flashing binaries to serial port /dev/ttyUSB0 (app at offset 0x10000)...

相关问题：esp32烧写报错；esp32自定义分区；esp32分区表偏移地址；

问题原因

1. 更新后开启了一些默认宏，导致 bootloader.bin 变大，占用了分区表的其他位置，导致冲突

解决方案

1. 使用 make menuconfig 修改 Offset of partition table 为 0x10000

2. 如果使用了用户自定义分区表，需要一一修改地址的 offset 或将所有 offset 置为空
