This online is space is for reporting issues in the codebase, this is certainly not a support forum!

Hi @LegendaryTeacherLiu, you need to compile the bootloader using the included makefile to produce the .hex file.

Check out the vagrant dev environment for a fully configured build environment. There are also instructions for building on OSX with homebrew in issue #28.

Thank you for your reply. I will try to do it. and Can I directly use the wav file on the mutable website to complete the firmware upgrade?

[gorcha]

Yep, you can update the firmware using the files available on the website here.

The manual has instructions for performing the update from a wav file:

Thank you again. Because I don't have the ability to program. then I will use the wav file on the website to upgrade the firmware.
