STM32H747 MP3 player (spiritMP3 decode)

cVass.1
Associate II

Hello everyone,

I'm on STM32H747, I use SpiritMP3 decode to play my music with an I2S DAC on the M7. This works very well.

The problem is when I want to dialogue between the two Cores, I use Domain D3.

But I have a "BusFault" which occurs after SpiritDecode, suddenly the Buffer which serves as communication between the two Cores crashes on the M4
