Here is an update on how to flash ESP8266 boards with 16MB flash memory for Win users.
Python and esptool is expected to be installed already.
I wrote a batch file that does all the required steps in a sequence sorting out all params for esptool.
The file name I used is ESP-Flash16MB.bat
and just contains these two lines:
esptool.py --port %1 --baud 460800 erase_flash
esptool.py --port %1 --baud 460800 write_flash -fm dio -fs 16MB 0x00000 %2 0xffc000 esp_init_data_default.bin
To use it, a cmd window needs to be opend and one has to navigate to the folder the two .bin files and the .bat file had been copied before:
(<- just example, this one I used)
(<- the .bat I described above)
Then just call the .bat file adding the com port number (mine was com27) and micropython .bin file from
to be flashed:
ESP-Flash16MB.bat com27 esp8266-20191220-v1.12.bin
Et voila, the module gets erased and both bin files flashed in a single go.
No hassle, no big deal even for beginners.
Just flashed all my Wemos D1 mini pros 16MB successfully with latest version of MP V1.12 we received as X-Mas present.
BTW: Thank you George!
Best wishes to all of you.
Merry X-Mas and Happy New Year!
