The Avnet S6LX9 Microboard is a small USB-Stick sized module containing a Spartan6 FPGA capable of running the Microblaze softcore processor together with RAM and FLASH memory. This board support pachage assumes that the Microblaze Bitfile available from the Avnet website is programmed into the FPGA.

This is the buildroot board support for the Avnet Spartan6 LX9 MicroBoard.
The Avnet S6LX9 Microboard is a small USB-Stick sized module containing
a Spartan6 FPGA capable of running the Microblaze softcore processor
together with RAM and FLASH memory.
The board can be bought from Avnet (avnet.com) or from Trenz Electronic
(www.trenz-electronic.de) for a low price.
To run the Linux built with buildroot you have to install the FPGA bitfile
and u-boot as described in the tutorial AvtS6LX9MicroBoard_SW302_PetaLinux
available on http://www.em.avnet.com/s6microboard
On this site also is a forum containing information on how to build your own
Microblaze processor for the Microboard.
The image file (default name is simpleImage.lx9_mmu.ub) has to be copied
to your tftp folder (often /tftpboot/) or can be programmed into the
board's SPI flash.
Sample session:
$ make s6lx9_microboard_defconfig
$ make
$ cp build/linux-<version>/arch/microblaze/boot/simpleImage.lx9_mmu.ub /tftpboot/br12.2a.ub
$ minicom
