I am porting a version of Redhat's embedded linux kernel to a new custom designed bd with the mpc860. I previously successfully used this kernel with the MBX dev bd, using NFS to access the remote RAM disk, thus booting the kernel and executing my app. Now I am using a local RAM disk on this new bd. The zImage (boot loader + zipped KERNEL + zipped RAM disk) is downloaded into the onboard RAM, starts its BOOT loader, unzips the kernel, unzips the RAM disk, starts booting the kernel code up to calling execve(/sbin/init). The sequence is shown below. I don't understand what is happening here with the "put_dirty_pages". /sbin/init is getting executed and /app is then attempted. There is 32M of RAM. 0x0000.0000 - 0x01ff.ffff zImage is downloaded into 0x0018.0000 and execution begins there: Executing Boot Loader...
