I got a few D1 clones https://www.aliexpress.com/item/5sets-D ... 26305.html and cant get the Arduino IDE to flash a working sketch to them. The flash looks to complete without error but on a reset they go into a bootloop with the following error:

But if I reflash NodeMCU to the units I can get Lua scripts to run so the modules seem fine:

Code: Select all

NodeMCU 0.9.5 build 20150318  powered by Lua 5.1.4
lua: cannot open init.lua

I have tried different modules/speeds/settings but nothing seems to work to get an arduino script ro work

thanks

Well I must say that this is embarrassing, after nearly a week of trying to get to the bottom (I could flash the two nodeMCU that I have just fine) I decided to uninstall/reinstall the esp8266 board from the board manager and all works fine.
