重启信息如下:

flash read err, 1000
ets_main.c 371
烧录配置信息如下

如果你的问题是烧录无效,那请确认你的烧录过程,参考:https://docs.espressif.com/projects/esp ... -and-flash 及熟悉 Get Started 相关过程。

因为 esp32 在上电后需要从 flash 的 0x1000 加载二级 bootloader,从而再引导用户程序。如果你擦除了 flash,那 0x1000 地址开始就全是 0xFF,esp32 芯片 rom bootloader 在从 0x1000 地址加载二级 bootloader 就会出错。从而出现你现在的 error log。

rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
flash read err, 1000
ets_main.c 371
