I get it after power on with non-os sdk 3.0.3
rtc_info->reason=2
rtc_info->exccause=0
...epc1=0x4024668c epc2=0x00000000 epc3=0x00000000 excvaddr=0x4010be30 depc=0x00000000
In the documentation "ESP8266 Reset Causes and Common Fatal Exception Causes" https://www.espressif.com/sites/default ... ses_en.pdf
reason=2 meaning Table 1-2: Fatal exception?
exccause=0 meaning Table 2-1: Invalid command/Damaged BIN binaries/Wild pointers?
Sorry but think the docs is a litle bit unclear on whats' what there
