I am unable to flash the example play_mp3 program onto my LyraT board. I am able to get ESP IDF example programs like blink to work, but I get compiler errors when I attempt to use the ESP ADF example. Im wondering if anyone can help me fix this. Sorry if this board is not meant for topics like this. Here is the output of 'make flash' for the play_mp3 example.

Hello,
I have the same problem today. Tell me if you find a solution please. I'am on linux and it's the first time I try to compile my project.

Thank you,

Nicolas

It turns out that my problem was I was using the wrong environmental variable for the esp idf directory. You need to be using the esp idf repo that comes bundled within the esp adf repo. The tutorial is not super clear on that. Hope this helps!

Hello,
thank you ! I found it too. On linux you have to use this : IDF_PATH = ~/esp/esp-adf/esp-idf/

best regards
