FreeBSD-HEAD now has sufficient support to bring up the wireless support on the Carambola 2.
The Carambola 2 (http://8devices.com/carambola-2) is an AR9330 based board with:
- AR9330 SoC
- 1x1 2GHz 802.11n support
- 16MiB NOR flash
- 64MiB RAM
- Five 10/100 ethernet ports via an on-chip ethernet switch
- USB host port
- RS232 console port
- Lots of GPIO pins
The development board breaks these out:
- 2 x 10/100 ports
- Reset and GPIO button
- USB Host port
- Power and RS232 console via mini-USB
- Install the build scripts
- Create /tftpboot/
- Install the lzma port - the default lzma compressor doesn't generate compatible images for uboot!
- (TODO) build an updated uboot port with the lzma kernel support
- Build FreeBSD:
# cd /path/to/head/checkout/src
# /path/to/buildscripts/build carambola2
- Power up the board via mini-USB and connect via console
- Press the escape key to interrupt the boot process (Any other key will expedite the timeout):

- TFTP and flash the combined userland/kernel. Ensure that the resulting image is no bigger than 0xfbb000 bytes else you will overwrite the calibration data!
