Re: [U-Boot-Users] USB storage support question
Yes, in cpu/arm920t/at91rm9200 is usb_ohci.{c,h}
My question is more along the lines of: what storage devices work on this interface, and what configuration flags (other than the ones I reported I set) are necessary to make those work?
Does it handle hard drives? Flash drives? What disk formats? FAT (tried it and it didn't work)? FAT32 (tried it and it didn't work)?
Thanks to you both,
Regards,
Matt

I have the AT91RM9200EK board, and I want to do something with the
USB
host ports on the board, so I've put the following in my
at91rm9200dk.h
config file:
The at91rm9200dk.h configuration is for the DK board, not the EK.
Are you sure this can work?
Is the ohci driver really there? Check cpu/arm920t/at91rm9200
The OHCI is integrated on the chip, so there should be no problem in most cases to use the DK configuration. There are a few small differences, but normally they do not affect
U-Boot.

It implements support for the Mass Storage Device class.
Does it handle hard drives? Flash drives? What disk formats? FAT (tried it and it didn't work)? FAT32 (tried it and it didn't work)?
It should work with all compatible mass storage devices - disk, memory sticks, all sorts of memory cards interfaced through a compatible card reader, etc. Note that not all devices actually follow the USB specs, so some of this simple don't work.
