I guess it could as I see “using namespace avr_audio_bootloader;” in the file bootloader.cc, but not sure how to do to make it work.
I tried without success:
I press the TAP button while I power on the module.
I have the .WAV going into CLOCK IN.
I play the .WAV.
No blinking, no upload.
In fact pressing TAP while powering on simply puts the module in option mode as usual.
Not in any mode ready to accept the firmware.
Of course I’m talking about a firmware which was tested and that I was able to flash via ISP without issue. I am interested in the .WAV procedure, as it’s easier to upload for the majority of users.
