Which looks correct (although you only need to do ecosconfig tree once at
the end, but that's harmless).

This is a red herring - you don't need to do these for redboot. This serial
driver is a full interrupt driven one. RedBoot uses a polled interface
built into every HAL instead.

That would be the obvious thing I thought of. But assuming you applied the
patch Gary Thomas did, did you enable the
CYGSEM_HAL_ARM_SA11X0_ASSABET_NEPONSET_TIMINGS option in ecos.ecc (before
running ecosconfig tree).
