Flashing PlatformIO projects

PlatformIO projects developed with LibreTiny can be flashed just like any other PIO project.

!!! abstract All binary files generated by PlatformIO will be in .pio/build/<my_board>/. The methods described below may require you to get a file from that directory.

This path will be referred to as **build directory**.

Built-in flasher

LibreTiny has a built-in firmware uploader, based on ltchiptool. Pressing Upload in PlatformIO IDE does all the work for you.

If you have more than one COM port, configure your PIO project first:

[env:my_board]
monitor_port = COM96
upload_port = COM96
