    @manitou,@wmxz,
    Is there a way to specify the CS when using uSDFS in SPI mode (audio board or when using the SD of the ili9341 display) iso the Sdio build-in pins? A bit like SD lib does?

    Hi Paul,

    I don't think it is a bad idea.
    I guess cached/uncached memory is independent of DTCM/OCRAM
    That would mean that data and DMA buffers can end up in static variables (at least 128K for...

    I am using MacOS 10.13.6 with Arduino IDE 1.8.5.
    I did not try if the behavior was different with another OS as the T3.6 is still recognized correctly. Only the T4 is giving issues.
    Thanks!

    Hi Kurt,

    My experience with the ILI9341 and the T4 (and T3.6 BTW) is that it is nice to switch between DMA and non DMA mode within your application.
