What is "ets Jun 8 2016 00:22:57"

Postby mobhuyan » Wed Jul 04, 2018 5:39 am

Hi All,

I am troubleshooting an occurrence of TG1WDT_SYS_RESET.

I am new to ESP32 and ESP-IDF. My stack is actually Mongoose OS. I am using a Sparkfun ESP32 Thing board. But before post my actual question (with sufficient details to accompany) I have this question.

I have noticed that in the console I get a line,

I am wondering it is it coming form.

In case you are interested, the corresponding potion of the console output below:

Code: Select all

It's the sign-on message of the ROM; it's the first thing that gets printed after the ESP32 powers on and the CPU starts up. It means the ROM for the ESP32 was compiled on Jun 8, slightly past midnight, possibly by a set of tired colleagues happy they finally could go home. I think ets stands for Espressif Task Scheduler; that name is a remnant of the ESP8266 ROM code and the scheduler that underpinned the non-os SDK for that, which was also used for some things in ROM.

(I've split the discussion of TG1WDT_SYS_RESET into a new topic, so it's easier for people to find it.)
