1) I downloaded the 1559 buildroot (1559 is the version on my verdex)
2) Followed instructions as per http://docwiki.gumstix.org/Robostix_gumstix_ISP
3) Programmed fuses - seemed ok…
4) Unable to read fuses…
5) Used AVRISP to reset clock fuse to use internal (Clock signal supplied to pin 24)
Seems as though the external Crystal is not providing clock !?
