The device tree file for the AIDA board is arch/powerpc/boot/dts/virtex440-ml507.dts.Īt Daresbury we elect (at least for the development phase) to load the Linux kernel using System ACE from a Compact Flash card as supported by all the Xilinx reference boards.

The following commands will then build a Linux kernel for the AIDA board.Ī default Linux configuration is taken from the file arch/powerpc/configs/44x/aida_defconfig.

#SIMPLEIMAGE LINUX MAC#

The ethernet MAC address needs to be set correctly since it is used by DHCP to obtain Linux boot options such as the IP address and location of the NFS Root File System. In the Daresbury installation the default command line parameter is bootargs = 'console=ttyS0 ip=on root=/dev/nfs rw'. The device tree file contains options such as the default boot-time command line and the ethernet MAC address. This is combined with the Linux kernel as the very last step of the kernel build to make the elf file. The device tree file for the ML507 is arch/powerpc/boot/dts/virtex440-ml507.dts.

#SIMPLEIMAGE LINUX CODE#

Release 2.6.28 of Linux introduces the Device Tree feature which attempts to pull together the options from the FPGA code which are required by the corresponding Linux drivers. The Linux kernel will be in the file arch/powerpc/boot/ The boot-time command line CONFIG_CMDLINE='' is actually defined later.Ĭd /opt/SoftDev/Xilinx/linux-2.6.31/ml507 The target to be built is defined by CONFIG_EXTRA_TARGETS='simpleImage.virtex440-ml507'.

The following commands will then build a Linux kernel for the ML507 board.Ī default Linux configuration is taken from the file arch/powerpc/configs/44x/ml507_defconfig.

Setenv PATH /opt/ELDK/4.2/usr/bin:/opt/ELDK/4.2/bin Remember to setup the ELDK using bash /opt/ELDK/4.2/eldk_init 4xx or source /opt/ELDK/4.2/ELDK.csh.Īlternatively add the following to an initialise script

Extract the compressed tarball and make it the directory structure /opt/SoftDev/Xilinx/linux-2.6.31. Xilinx Open Source Wiki site and more specifically the Xilinx projects page.įor the latest release (currently 2.6.31) locate the project and select tree. Since release 2.6.28 introduces a new way to handle devices embedded into the fabric of the FPGA (such as ethernet and all 'user' devices) both 2.6.25 (ML403) and 2.6.28 (ML405 and ML507) are currently in use. The last Linux release which supports the architecture ppc is 2.6.25. The PowerPC processors 405 and 440 and the architecture powerpc have now been merged into the mainstream Linux distribution (as of release 2.6.28). The command bash /opt/ELDK/4.2/eldk_init 4xx sets the environment variablesĪRCH, CROSS_COMPILE and PATH needed for building the Linux kernel.Īlternatively using csh the command is source /opt/ELDK/4.2/ELDK.csh These steps can be repeated for other processor types such as ppc_74xxĪ root filesystem suitable for Virtex4/5 can now be found in /opt/ELDK/4.2/ppc_4xx.Ĭross compilers and other tools needed to built a Linux kernel can be found in /opt/ELDK/4.2/usr/bin. The next step DOES have to be performed using the superuser ID. On nnlxb create the directory /opt/ELDK/4.2 This can be done using any desired ID it does not have to be done using the superuser ID. Mount in your Linux system using something like:

#SIMPLEIMAGE LINUX ISO#

Burn the iso image to a DVD or use the file directly as a DVD (for example VMware).This contains the ELDK for the ppc_4xx processors (405 and 440) and the ppc_74xx processor (used in MVME5500). The most recent version is 4.2 and this is the iso image for use with a Linux X86 host. Obtain the ELDK from the DENX web site.The Virtex 4 PPC core is a PPC 405 processor and the Virtex 5 PPC core is a PPC 440 processor.

#SIMPLEIMAGE LINUX INSTALL#

The first step is to obtain and install the EDLK for the required PowerPC processor.

(2) Embedded Linux Development Linux (ELDK) Specific installation and build steps are given for the installation on the system nnlxb at Daresbury. Specific boards for which Linux systems have been built are the Xilinx reference boards ML403, ML405 (Virtex 4) and ML507 (Virtex 5).
