The Y-Box is coming along slowly but steadily. Highlights since my
last post:
- flashing of the KL26 works now (not perfectly, but good enough to
be useful),
- the crystal -> CC2543 -> KL26 -> PLL -> USB clock path, with the
CC2543 controlled over its debug interface from the KL26 and
dividing the 32 MHz crystal clock to 2 MHz using a timer, works.
- the KL26 enumerates on USB.
A lot more details can be found here:

To do:
- program CC2543 Flash from the outside
- implement DFU on the KL26. For now, there should be two DFU
targets:
- KL26 Flash (minus the area occupyed by the DFU loader)
- CC2543 Flash
In the future, there may be more targets:
- pairing key
- certificates/keys for firmware upload verification
- do something with the RF side of the CC2543.
So far, all the functionality will also be used in Anelok. DFU may
be an Y-Box-only thing (Anlok can use the memory card instead),
though I may add it to Anelok at least for development, too.
