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 <hit the reset button on the S6LX9 Microboard> Icache:ON Dcache:ON U-Boot Start:0x83f00000 SF: Got idcode 20 ba 18 10 01 *** Warning - bad CRC, using default environment Net: Xilinx_Emaclite MAC: 00:0a:35:00:63:37 U-BOOT for Avnet-LX9-Microboard-AXI-tiny-13.1 BOOTP broadcast 1 DHCP client bound to address 192.168.11.122 Hit any key to stop autoboot: 0 U-Boot-PetaLinux> tftp br12.2a.ub Using Xilinx_Emaclite device TFTP from server 192.168.11.10; our IP address is 192.168.11.122 Filename 'br12.2a.ub'.
