Hi Neelu, The easiest way to get a good baseline with the board and the kernel is to use the bitstream for the board that we provide in the file, linux_support.tar.gz, on http://git.xilinx.com.
In the PPC440 directory of the support file, there's a bit stream for the board. If you don't use a Xilinx probe to download to the board, you will need to create an ACE file from that bit stream, but it sounds like you know how to do that. I know the state of the Xilinx Git tree, but I don't know the state of Grant's for sure. We have baselined our Git tree such that you should be able to make it work quick and easy (that's our goal). To build arch/powerpc, the following commands should create zImage in the arch/powerpc/boot directory that can be used with the bitstream from the linux_support.tar.gz file. I am currently using the ELDK 4.1 tools to build the kernel. > make ARCH=powerpc ml507_defconfig > make ARCH=powerpc zImage We also provide a ramdisk image in the support file, you can build it also after copying the ramdisk images into the arch/powerpc/boot directory. The default command line of the kernel, in the ml507.dts file in the arch/powerpc/boot/dts directory, is setup to use the ramdisk. > make ARCH=powerpc zImage.initrd Hope that helps, John Linn -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of somshekar c kadam Sent: Monday, June 02, 2008 4:19 PM To: linuxppc-embedded@ozlabs.org Subject: ML507 EDK 10.1 Hi All, Currently I am working with ML507 Base Reference design. I have installed Eval 10.1 edk I am bale to create ace file using xmd with base download.bit. and able to boot the board. Now I want to boot the board with Xilinx Linux kernel from Xilinx git tree. I am facing compilation problem with zImage.dts for ml507_defconfig. now I need to create ace file for Linux for ML507. I tried creating zImage.dts its failing. Kernel error see below Please help or give some pointers wherein I can compile zImge.dts. this is from latest git tree. Seems for me arch/powerpc wrapper code is broken. Please suggest. currently I have no bdi I need to stick to Ace compact Flash booting. Also bit confused where we have two git tree one is Xilinx git tree one more from Grant Likely which should I use ?
