串口下载报错，如何切换芯片型号

在Windows上使用VScode进行编译LED例程下载，
提示A fatal error occurred: This chip is ESP32-C3 not ESP32. Wrong --chip argument?，
如何切换芯片型号

[ESP_ICY]

使用命令

Code: Select all

 idf.py set-target xxxx

，比如你要用 ESP32 系列芯片，就写

Code: Select all

idf.py set-target esp32

，详细可以查看IDF编程指南中的该部分：https://docs.espressif.com/projects/esp ... idf-target

芯片类型已改为esp32c3，但仍出现报错

先执行

Code: Select all

idf.py fullclean

或者

Code: Select all

rm -rf build/

操作清除刚才已经编译好的 build文件夹然后再设置新的芯片型号，再执行

Code: Select all

idy.py build 

进行重新烧录。
