lyrat开发板无法焼写

Postby caishiming777 » Tue Jun 15, 2021 9:47 am

测试lyrat开发板例程play_mp3,前面的过程挺顺利,到最后焼写一步怎么都不行,按照提示按mode键reset键进入download模式,putty也有反馈waiting for download,在esp-idf cmd里面总是说串口无法访问,请问有谁遇到过吗?

raise SerialException("could not open port {!r}: {!r}".format(self.portstr, ctypes.WinError()))
serial.serialutil.SerialException: could not open port 'COM3': PermissionError(13, '拒绝访问。', None, 5)
CMake Error at run_cmd.cmake:14 (message):
esptool.py failed
Call Stack (most recent call first):
run_esptool.cmake:21 (include)

Lyrat v4.3 如果选择手动烧写模式, 则是 先按 boot 键, 然后再按 rst 键, 然后释放按键即可。

并不是你说的 mode 键, 建议仔细阅读文档 :https://docs.espressif.com/projects/esp ... lyrat.html
