Explanation of boot messages

[kolban]

With respect to this image shown of a boot of the device ...

Would it be possible to provide an explanation of each of the fields?

Hi,

1） rst_cause：
1： power-on
2： external-reset
4： hardware watchdog-reset

2）The first parameter of boot_mode:
1: ESP8266 is in UART-down mode (download FW into Flash)
3: ESP8266 is in Flash-boot mode

If value of “chksum” == value of “csum”, it means read flash correctly during booting.

These are the information users may need to know, we will add these into documentation. Other logs are for internal use, no explanation.

Thanks for your interest in Espressif Systems and ESP8266 !
