ESP8266 常见问题

上电输出以下信息

ets Jan  8 2013,rst cause:1, boot mode:(3,6)

In the bootup message ‘boot mode:(x,y)’ three low bits of x are {MTDO, GPIO0, GPIO2}.

The Espressif code can boot in different modes, selected on power-up based on GPIO pin levels. (MTDO is equivalent to GPIO15).

MTDO	GPIO0	GPIO2	Mode	Description
L	L	H	UART	Download code from UART
L	H	H	Flash	Boot from SPI Flash
H	x	x	SDIO	Boot from SD-card
