经过查询后了解到,ESP32开发板在使用串口烧录程序的时候需要进入烧录模式,也就是需要将默认高电平的IO0端口电压拉低。一般只要按下开发板上面的BOOT键就可以了,但是经过实践发现并不行,于是我在网上找到了相应的解决方法:【ESP32烧录异常解决办法-哔哩哔哩】网页链接。按照UP主文中所说的话:ESP32自动下载电路时序有...
Basically, I have a problem debugging the ESP32 c3 over the inbuilt USB/JTAG from within eclipse-cdt + ESP-IDF plugin. Specifically, I can erase/flash/verify, as well as connect and run OpenOCD with all the single stepping goodness just fine . . . *IF* and *ONLY IF* I place my ...

看了一下显示的log信息，貌似题主已经上传成功了，通常来说烧录之前要先保证你的硬件下载电路以及驱动没有问题，把你的板子连接到电脑上面然后打开设备管理器查看串行设备有没有具体设备型号显示，确保这一步没问题之后，检查自动下载电路是否有问题，esp32烧录时需要对IO0进行上下拉操作，做好这些一般来说就都没问题...
