I used the dev board 1.0 (black) connecting 2x AA on 3.3V pin.
When the batteries went empty, the Lua console never worked anymore.
I tried blanking all memory offsets, flashing with different firmware versions with default settings in ESP8266Flasher.exe. With DIO, I have garbage ... MEM CHECK FAIL!!! @ 115200, but when using QIO, the bootloader log @ 74880 is :
ets Jan 8 2013,rst cause:2, boot mode:(3,7)

tail 4
chksum 0xef
load 0x33333333, len 858993459, room 4
If I set ESplorer @ 9600, its always waiting a communication
Communication with MCU...
I tried a simple code with Arduino IDE, it's working.
What can I try to get back NodeMCU ?
Thank you
