最近在搭建环境,准备上手ESP32,买了NodeMCU-32S Lua WiFi物联网开发板串口WiFi+蓝牙模块ESP32开发板。
用的是win10里面的ubuntu。
环境,编译都过了,用 idf.py flash 烧固件进开发板的时候出现这样的问题:

Serial port /dev/ttyS18

Detecting chip type... ESP32
Running ninja in directory /mnt/e/ESP32/SDK/esp-idf/examples/get-started/hello_world/build

ninja: no work to do.

另外还想请教一下,这个开发板能用esp-idf这个SDK吗?还是只能用nodemcu-firmware。

可以使用这个SDK,看样子是波特率过高了,你设置下载波特率为115200.
