3) HSCMI TX DMA support is currently commented out.
4) I believe that there is an issue when the internal AT25 FLASH is
formatted by NuttX. That format works fine with Linux, but does not
appear to work with Windows. Reformatting on Windows can resolve this.
NOTE: This is not a SAMA5Dx issue.
UPDATE: Two important bugs were recently fixed in the NuttX FAT
formatting function (mkfatfs). It is likely that these fixes will
eliminate this issue, but that has not yet been verified.
5) CAN testing has not yet been performed due to issues with cabling. I
just do not have a good test bed (or sufficient CAN knowledge) for
good CAN testing.
6) The NxWM example does not work well. This example was designed to work
with much smaller displays and does not look good or work well with the
SAMA5D3-Xplained's 800x480 display. See above for details.
7) I have a Camera, but there is still no ISI driver. I am not sure what to
do with the camera. NuttX needs something like V4L to provide the
definition for what a camera driver is supposed to do.
I will probably develop a test harness for ISI, but it is of only
minimal value with no OS infrastructure to deal with images and video.
