USB?

Altera_Forum · ‎03-10-2005

I've noticed that the USB drivers section doesn't appear to have any support at all, not even generic stuff like USB mass storage support (the 2.6.9 release). Does this mean that uClinux/Nios II can't use any USB devices? I'm most concerned about mass storage.

Thanks,

All the generic USB support is in the kernel source tree. The reason you don't see it is because "Support for Host-side USB" depends itself on PCI and some architectures. You can just modify the file drivers/usb/Kconfig (add the text in blue):

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

menu "USB support"

# ARM SA1111 chips have a non-PCI based "OHCI-compatible" USB host interface.# Altera NIOS softcore processors a non-PCI based USB host interface.

config USB

tristate "Support for Host-side USB"

depends on PCI || SA1111 || ARCH_OMAP1510 || ARCH_OMAP1610 || ARCH_LH7A404 || NIOS2[/b]

--- Quote End ---

You will be able to see the class drivers after this modification.

Just as a correction,

|| NIOS

was already in the Kconfig file. I added

|| NIOS2 || NIOS2NOMMU

though, and that worked.
