BSP for Microchip ATSAMA5D27-SOM1-EK1

[dufault at hda.com]

Thank you for the advice.  I will not need USB, but will need SDRAM and don’t need poor support.  Microchip? You tried to push RTEMS for this platform tied to space applications, are you monitoring this?  The platform looks like just what I need but not if you’re not supporting it.

Half a year after reporting this bug, Microchip confirmed it, but did not plan any fix for it. BTW: The conbination (USB+SDRAM) was also available on Microchip's evaluation board, but obviously was not tested together at Microchips labs...
