Does the ASF4/Atmel Start source automatically update, or is this a manual process?
With ASF3, you manually selected which version of ASF is used in your project. With ASF4 this is not the case (or if it is, there's no where obvious to do so).
Assuming ASF4 auto-updates, are new updates/bug fixes added by opening up the configuration page and hitting "GENERATE PROJECT"?
Finally, Is there anywhere I can see a list of what drivers/middleware is available in ASF4 for each processor? The documentation shows that there should be a SPI DMA driver available, but I do not see this as an option on any of the SPI components added to my SAMG55 based project.
