Hello, I work on a custom board based on a virtex 2 pro FPGA and 8Mbytes of SDRAM. Untill now I used a 2.4.31 linux ppc kernel with John Williams patches and uclinux distribution and everything worked perfectly. I've decided to move to the latest 2.6 version from kernel.org (2.6.23.1) with an initramfs containing a busybox. My complete zImage including the initramfs has a size of 900Kbytes. I made some tests with a ML300 board and I managed to get a shell easily. When I migrated to the custom board, I had the "Now booting the kernel" message and then nothing. When I trace the code running on the ppc with the debugger, execution seems to be stuck in some early initialization code. I managed to reproduce the problem on the ML300 using "mem=8m" parameter on the bootline. With "mem=16m" the kernel boots correctly. I'm really surprised by the amount of RAM required to boot the kernel. Is there a way to make it boot with only 8Mbytes of RAM ? Thanks for your help.
