Hi

I am using BNO055, I2S mic and SD-card.

I2S mic is on CoreM4, SD is dedicated on CoreM0.

If I add the BNO055 to CoreM0, sometimes it races with the SDcard writing. If I add it to CoreM4, it slows down the I2S because the I2C is slower compared to the I2S bus.

I can't find a way to add DMA channel to the I2C.

Any advice ?

thanks
