Flyswatter JTAG and AVR32

Today I soldered AVR32 adapter for Flyswatter JTAG. Actually it's very simple task - just connect respective pins and make common ground wire. No capacitors, resistors or MOSFETs. Idea was to make it nice and neat but having bought wrong breadboard and soldered first headers in a wrong place I just let it flow and here it is: From aesthetics point of view suck, but it also works and it's everything I need:
Info : JTAG tap: avr32.cpu tap/device found: 0x21e8203f (mfg: 0x01f, part: 0x1e82, ver: 0x2) Warn : JTAG tap: avr32.cpu UNEXPECTED: 0x21e8203f (mfg: 0x01f, part: 0x1e82, ver: 0x2)

FreeBSD/avr32 spotted in the wild

A very preliminary port to the AVR32 has been spotted in the wild. Arnar Mar Sig posted a dmesg of FreeBSD/avr32. You can find his post through this link.

For those of you unfamiliar with the AVR32 architecture, it is an architecture that is used primarily in embedded applications. AVR may be initials familiar to many readers as microcontrollers. Atmel took its know-how and created a 32-bit version of this architecture basically from scratch.

You can find more information about the processor at atmel's web site, or at wikipedia.

The work here clearly is preliminary, but it is very cool none the less. FreeBSD embedded is on the move...
