I have the board booting from AT91bootstrap and Uboot, from QSPI no problem. Downloading code using JLink from Windows/eclipse is fine, but the debugging is broken/mis-configured. I will probably have another go at a Windows-hosted development environment and have the arm cross compilers installed already: since it works for the Atmel "softpack" stuff from which I derived my initial board debugging code (before moving to NuttX) I see no reason why it shouldn't work for NuttX using tool chains, within Eclipse, once I finally get my head around it and find the magic trick!
Seems I have a few things more to try now, at least.
