Sorry, I don't think you understand me properly.
1) I can't see the itunes music on the apple firmware. it's fine on itunes and ipodlinux. I though TagCache was to be run so you could see itunes on rockbox.
2)I can't get the rockbox firmware working really at all. It just shows the flash screen and then has an error about a partition not being found and asks for USB. I presume the bootloader (Loader 2 from ipodlinux) is working fine as it comes up on hard reboot with the option of Apple OS (which works), ipodlinux (which works), and rockbox.
BTW, please just reply, don't edit my message unless needed. Thanks VERY much,
Simon
