we have now the first scan results, i.e. the (U-Boot based) driver [2] is able to program
the RFID reader chip correctly to scan for ISO15693 tags. It now finds tags,
and identifies collisions of multiple tags (but does not yet resolve them).

Some next steps (where volunteers could step in): port the (simple)
u-boot driver to the kernel. And connect the FRIDB really to a Freerunner
SPI interface (we currently test on a BeagleBoard since it is easier
to develop U-Boot code on the BB).

Anyone interested to experiment? We will receive more PCBs next week.

BR,
Nikolaus
