@Jason2866 that is true. We need PIO to update their stuff to generate bins, like we do in the IDE.

@me-no-dev Interested in reason for the change. What is the benefit for using *.elf files?

[ivankravets]

Thanks, @me-no-dev, for pinging us. We will update our develop branch.

[me-no-dev]

@Jason2866 if we use precompiled bins, the bootloader complains that the checksum of the firmware is wrong any time that settings (partitions, size, speed, etc.) differ from what the bootloader was compiled with. In order to get around that, we need to use elfs and turn them into bins with the same settings as the firmware at build time.

@ivankravets you are welcome :) Sorry I did not mention this earlier!

What does this do to OTA updates?

[me-no-dev]

@TD-er as long as you keep the settings the same, it does nothing to OTA. You will see the error if you change flash speed/size.

[TD-er]

So no issues with checksums?

[me-no-dev]

no issues with checksums. elf2bin is done based on flash/psram settings, not based on the firmware image.

Thx! Tested and working.
