BSP for Microchip ATSAMA5D27-SOM1-EK1

[Thomas Dörfler]

Peter,

just to make you aware: we designed a board with the ATSAMV7 chip and hit some nasty and at least one really ugly bug: operating the USB interface concurrently with external SDRAM does not work. 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...

So: I recommend you to tripple check, whether the ATSAMA5 meets all of your expectations.


Kind regards,

Thomas.

Betreff: BSP for Microchip ATSAMA5D27-SOM1-EK1

I need to evaluate this for a multi-chip application.

This part is a result of Microchip’s take-over of ATMEL.  I’m double-checking that to create a BSP based on this I should start with the existing ATSAMV7 BSP, I think the peripherals (e.g. network chip and so on) are the same as the existing ATSAMV7 port.
