Flashing LOLin NodeMCU v3

-

Published on 2020-06-29 17:58:00+02:00 -

Republishing old content. This is from when I bought and flashed my first NodeMCU clone (perhaps "loose -implementation"?) of NodeMCU v3 called LOLin v3. -

This little board is using CH304G TTL to USB converter, so if you happen to work on Windows you must make sure you -have the driver installed beforehand. Mentioned chip is quite common, and I've seen it on various Arduino, so there is -a high chance that you already have it. -

Without further notes, here is the specification:

Baud rateFlash modeFlash sizeFlash frequency -
9600 QIO 4MiB 40MHz -
-

You will need a combined firmware binary. If you are compiling it by yourself, I suggest using one of the development -branches. If you don't have environment set up there are online building services available e.g. -NodeMCU custom builds. -

To write the firmware use e.g. esptool:

-
-$ esptool.py --port /dev/ttyUSB0 --baud 9600 erase_flash
-$ esptool.py --port /dev/ttyUSB0 --baud 9600 write_flash \
-  --flash_mode qio --flash_size 4MB --flash_freq 40m \
-  0x00000 combined-firmware-file.bin
-
-

To test it you can connect to it with e.g. screen:

-
-$ screen /dev/ttyUSB0 115200
-
-

Or use your favourite terminal emulator:

-
-$ st -l /dev/ttyUSB0 115200
