That's the official repo so I don't think you'll find a newer version.

Do you have the other files on the USB disc, ie start*.elf, fixup*.dat, etc?

Did you try another USB disc, in case there's something about this
particular one the bootloader doesn't like?  On PCs it's not unknown for
them to refuse to boot certain USB devices.  Kernels have more flexibility
to work around strange implementation quirks than firmware does.
