Hi everyone,
I am not sure if this is a linux question or a u-boot question. I have a custom MPC8540 board running U-boot 1.1.4. With a NFS root configuration, I have booted and run 2.6.15 with memory from 256MB to 2GB. If I build a ramdisk image (or even if I use the ramdisk image with the 85xx version of ELDK 4.0) and then combine it with the kernel image (vmlinux.gz) using "mkimage", the linux boot blows out with an oops if I boot the board with more that 512MB of DRAM. From the U-boot output, it looks like the ramdisk image is getting copied to the upper portion of DRAM. Is it possible that the kernel doesn't map enough DRAM to allow the image to be read? I haven't spent a lot of time debugging this once I saw that the 512MB configuration worked OK. Has anyone run into this? Thanks, Scott ___________________________________________________________________ Scott N.
