Re: LoLin NodeMcu v3 - Problem with flashing?

First try to erase the flash completely to ensure it doesn't contain any remains from a previous SDK. The docs say to use the following command http://nodemcu.readthedocs.io/en/dev/en ... #esptoolpy:
Then flash again and add the option "-fm dio" just to be on the safe side. If it works now then you can try again flashing with "-fm qio". QIO is favorable in terms of flash memory access performance but might not work on all modules out there.
Code: Select all
esptool.py --port <serial-port-of-ESP8266> erase_flash
Then flash again and add the option "-fm dio" just to be on the safe side. If it works now then you can try again flashing with "-fm qio". QIO is favorable in terms of flash memory access performance but might not work on all modules out there.
