1This is the buildroot board support for the Avnet Spartan6 LX9 MicroBoard.
2
3The Avnet S6LX9 Microboard is a small USB-Stick sized module containing
4a Spartan6 FPGA capable of running the Microblaze softcore processor
5together with RAM and FLASH memory.
6
7The board can be bought from Avnet (avnet.com) or from Trenz Electronic
8(www.trenz-electronic.de) for a low price.
9
10To run the Linux built with buildroot you have to install the FPGA bitfile
11and u-boot as described in the tutorial AvtS6LX9MicroBoard_SW302_PetaLinux
12available on http://www.em.avnet.com/s6microboard
13
14On this site also is a forum containing information on how to build your own
15Microblaze processor for the Microboard.
16
17The image file (default name is simpleImage.lx9_mmu.ub) has to be copied
18to your tftp folder (often /tftpboot/) or can be programmed into the
19board's SPI flash.
