Finally got access to hardware again. So here's the full o/p from my ARM target. Still trying to get a root file system on a RAM disk. Without any success. Here's o/p from my booting.... Again apologies if its in-appropriate. I'm absolutely stuck!
The RAM disk is programmed into FLASH at 0x8200000. The kernel is tftpeed to RAM at 0x30300000
my bootargs are root=/dev/ram
A couple of questions before I'm roasted.......
-> Do I need CONFIG_SETUP_MEMORY_TAGS enabled -> Do I need CONFIG_INITRD_TAG enabled -> Should CONFIG_DEVFS_FS be enabled in kernel? -> Should CONFIG_DEVFS_MOUNT be enabled in kernel -> When running mkimage for RAM disk what relevance are load and entry addresses. My 'Karim Yaghmour' book says not needed. -> Do I need to specify 'initrd=' -> Do I need to specify 'initrd_start='
Sorry for appearing dumb but there are so many combinations...... and I have already tried so many my head is spinning.
Thanks, Luke
