.lua are deleted when trying to copy nodemcu to other ESP
Posted: Thu May 17, 2018 1:48 pmHi!
I'm trying to make a full flash dump of ESP8266 running nodemcu (with some .lua files) to make a copy of it. I'm using esptool.py for a dump. Like this: esptool.py.exe -p COM3 -b 230400 read_flash 0 0x200000 test.bin
When I look inside test.bin, I can see my lua code. So, those files are definitely there. But, when I upload this .bin to another ESP , nodemcu starts filesystem format procedure. Therefore, all .lua files are deleted. NodeMCU build itself seems to be fine.
Why does this happen if I make a full dump of the flash? Is there a register flag or something what defines that nodemcu should format filesystem? How can I copy ESP keeping all .lua files in place?
