Uploading code to the module

Pin	Level

GPIO0	Low
GPIO2	High

Pinout is in Hardware versions

Uploading

/opt/Espressif/esptool-py/esptool.py --port /dev/ttyUSB0 write_flash 0x00000 0x00000.bin
sleep 3
/opt/Espressif/esptool-py/esptool.py --port /dev/ttyUSB0 write_flash 0x40000 0x40000.bin

Caveats

Note to Windows users: For the port argument, use standard port names, e.g. COM3.
Sometimes a reset is required between uploading the first and second file.
There are some cases that the upload fails with "Failed to leave Flash mode". This is normal your upload went without issues.
