I guess both symbol and footprint are available.
I know it sounds silly considering the very minor work of adding a jumper, but will it be used on the Alpha? Can it wait until the next board? Will the Alpha be less useful if we don't add the jumper? > Also note that SPI flash /WP signals do not always control write > protect directly, but only provide one input to the write protect > logic, with a software-settable bit being another part of the actual > write protect state. Another good reason to question the value of a jumper there... until we know what we are trying to defend against. > > Alpha train > > Is there a production schedule now?
