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.
|
||
|

|
||
|
|
|
||
|
|
$ make s6lx9_microboard_defconfig
|

|
|
$ make

$ cp build/linux-<version>/arch/microblaze/boot/simpleImage.lx9_mmu.ub /tftpboot/br12.2a.ub
