initramfs-tips
uploaded an alternate kernel (initramfs) you should be able to mess around with for a week or so...
(just copy it over the existing kernel with the name 'kernel' it does not use the rootfs and can't save settings but you could mount that partition to save config files there)
(the same boot commands will load it ok)
(it could and should also be used to make dd images of mtd and mmcblk0 in case you ever need them for recovery mmc is 4G tho'... so you need another partition (mount /dev/sda3 /mnt) or pipe it direct to netcat>pc if unsure hold off or ask)
seems they're stripping this now... so we have to hardcode it in the dts/dtb(kernel) rather than get it from the bootloader...
my old buildroots dont run... (but it is time for a rebase/refresh) so hopefully might get some time this week to create some up to date images... edit: got it running so there is now;
- v2.1 kernel with hardcoded /dev/sda2 + rootfs
- 2xinitramfs files you can copy over the kernel (if 2.1 fails) (use the biggest I just copied random ones)
after that... we just need to tidy up the uboot commands a little and save them...
(we can make the usb booting automatic so if you take out the drive it will boot oem... saves you from having to edit in the future)
(rebase-mostly-done: thanks slh for the lowercase mtd code... saved me 3-5hours)
let me know if there are any programs/kmods you need...
