Hello everyone, I was able to make it work. Here you have bachelor thesis Myproject from github.

You need to modify the SAI configuration like this.

In the sound.c from my project you have a one shot task that will read a wav file and play the audio.

things to take in concideration, if you are going to use RTOS, if a task with higher pririty than the one play the sound is call and start running the audio will stuck in a infinte loop waiting for the dma.

Hi,

> I am trying to play wav audio files from and sd card.

Great idea...i had also, 3 y ago. 🙂

Player running fine...can play wav, flac, mp3 ; from SDcard and USB stick; to ES9038 DAC via SAI ;

now with small TFT on SPI , and ESP for wifi/web radio ;

but i didnt use touchGFX or any BSP files , i made it myself, as i planned . 🙂

So about the BSP not working...no surprise. I also had no luck with these useless "examples" ...
