通过espefuse.py --port com4 burn_efuse VDD_SPI_AS_GPIO 1对ESP32C3的eFuse中BLOCK0的VDD_SPI_AS_GPIO写入1,从而将VDD_SPI引脚作为普通I/O来使用,写入前eFuse中的所有BLOCK内容如图: eFuse查询.png 写入成功后再次检测如图: eFuse修改结果(标注).png 但是此后该芯片再也不能下载程序,具体错误如图: ...

Re: ESP32C3通过eFuse将VDD_SPI_AS_GPIO设置为1后,程序MD5不匹配 Quote Postby86yhs@163.com»Mon Oct 30, 2023 5:30 am 遇到了同样问题, 改熔丝显示成功后,本来期待多一个gpio11可以用,现在好了,程序不能下载,不能运行,一个io口也没得用了。
