ARM support in latest ELDK (4.2) seems to lag a bit ...

This means that you're doing the soft-reset sequence I told you above
(in boards/atmel/at91sam9260ek/at91sam9260ek.c). Maybe your board
doesn't need this, try commenting out the relevant code in
at91sam9260ek_macb_hw_init() (keep only the gpio set_A/B_periph().
