Hi Gerd,

I was trying your latest wifi-testing (recently rebased) branch.  I wanted
to play with the DMA stuff.  For some reason that isn't working for me.
Both the mmc0 and mmc1 are in PIO mode.

Looking at your code, I was curious why you are enabling DMA for the sdhost
controller (mmc card) instead of the SDHCI controller (wifi/bt)?

Cheers,
Don
