程序卡在bootloader 中,waiting for download

Postby myttl1136 » Tue Jan 25, 2022 5:24 am

我手头上有ESP32-WROVER-E 的模块,用来做二次开发,烧写上程序后,log会显示如下:
ets Jul 29 2019 12:21:46

rst:0x1 (POWERON_RESET),boot:0x0 (DOWNLOAD_BOOT(UART0/UART1/SDIO_FEI_FEO_V2))
waiting for download

请问是不是会由于某个pin,导致卡在bootloader中?这个等待download 是由什么触发的?

受到 strapping 引脚的影响,检查下 GPIO0是否被拉低
