Well, I didn't figure it out until I looked at the FTDI site, where they
say that JTAG-over-MPSSE is possible. Although I can't see *exactly* how
it works, since the example they give is written in Delphi, of all
things. I guess this is also completely hinged on someone implementing
support for the MPSSE calls into OpenOCD, and the mc1322x specific JTAG
data, and the feature doesn't mean much before then?
If the Econotag has onboard JTAG, does that mean that there's a way to
do a similar thing with the redbee-dev, not needed a JTAG pod? Because
it has an LED on it, which is immensely useful. Several OEM dev boards
I've seen have a JTAG interface built onto the board, but it usually
looks to be a fairly complex unit, involving CPLD's and secondary MCU's.
Also, while we're talking, for the collective record, the newlib
implementation of printf which CodeSourcery uses does have %f, and it works.
