Hi,
    I am using an at91rm9200dk custom board.I want  to boot kernel and
ram disk from the usb stick.for that i tried to enable the usb support
in the uboot.but now i am getting a message like no storage devices
found .
i gave the configurations in include/configs/at91rm9200dk.h
like follows

#define CONFIG_DOS_PARTITION 1
#define CONFIG_USB_OHCI      1
#define CONFIG_USB_STORAGE  1

#define CONFIG_COMMANDS		\
		       ((CONFIG_CMD_DFL | CFG_CMD_MII | CFG_CMD_NET | CFG_CMD_USB | \
			CFG_CMD_DHCP ) & \
		      ~(CFG_CMD_BDI | \
			CFG_CMD_IMI | \
			CFG_CMD_AUTOSCRIPT | \
			CFG_CMD_FPGA | \
			CFG_CMD_MISC | \
			CFG_CMD_LOADS))

Is this configuration is right?
i am not able to acess the USB stick using Storage USB Commands. My
U-boot version is 1.1.5. 
 Any one can help?
regards 
Aneesh

You should use the new ohci driver and define CONFIG_USB_OHCI_NEW. But
that alone is not enough, please checkout doc/README.generic_usb_ohci.

Oh, and please update your U-Boot version to top of git before anything
else.

Someone else has already suggested using a current
U-Boot version via git rather than v1.1.5, so I
will restrict my comments to the old 1.1.5 version.

I have a AT91SAM9261-EK (v1.1.5) with
working USB Storage that also includes  ...

#define LITTLEENDIAN        1

as part of the USB configuration.

--- When you get USB Storage working - either v1.1.5 or git ---

You will probably need (at least want)

#define CFG_CMD_FAT

or

#define CFG_CMD_EXT2

to access the FAT or ext2 directories and
files on the USB Storage device.

This may be useful if your kernel and
ramdisk are files on a FAT/ext2 filesystem
(rather than at a fixed locations on the
raw USB device).

u-boot> setenv bootcmd ...
u-boot> saveenv

--- VFAT ---

You may want to include the following for
long filename support (for FAT filesystems):

#define CONFIG_SUPPORT_VFAT

--- FAT16 vs. FAT32 - Atmel U-Boot v1.1.5 issue? ---

I have found that the USB support is better
when the USB Storage device is FAT16 formatted
rather than FAT32 formatted.  For some reason
not all files were accessible on FAT32
formatted media, but I never had any problem
with FAT16 formatted media.

Sincerely,

Ken Fuchs

Can you try this patch?
In the git log there is another patch for vfat to be applied.

I tried it, but it did not work.

I also tried the earlier patch where Michael Trimarchi
added the CHECK_CLUST() macro, but it still doesn't work.

Next, I compared my fs/fat/fat.c with what was in git a few hours ago.
The only significant differences were in the fat_register_device(),
but after making my fs/fat/fat.c match what's in git (except for
trivial whitespace differences and recent CONFIG_* & CFG_* handling
differences, it still fails to work properly.

Can you give an image of it?

--- Introduction ---

This thread concerns possible problems with fs/fat/fat.c
(incorrect fatls output and inaccessible files via
fatload) even when recent "git" patches have been applied
to fat.c.  VFAT is enabled.

Michael Trimarchi wrote:

> Can you give an image of it?

(He is referring to the FAT32 image where "fatls usb 0:1 /"
resulted in a clearly garbled/incorrect directory listing.)

Rather than that particular image, I decided to write two
scripts that do most of the work building two other FAT32
images that trigger problems with "fatls usb 0:1 /".  Note
that one FAT32 image is made on XP/Cygwin (mkpen) and the
other on FLOSS/Linux ..err.. GNU/Linux (mklpen).  Note that
two FAT32 images they make do have exactly the same files and
file content, built in exactly the same order, but since the
filesystem code is different, the metadata will probably also
be different ... different inodes ... etc.

The attached mkpen is the XP/Cygwin build script and
u-boot-usb-bug.img.bz2 is a bzip2 compression of the
XP FAT32 image that demonstrates the problems (shown
below) when accessed by U-Boot's fatls.

The attached mklpen automates the whole process on a
Linux host, except you still need to enter the command
./mklpen and move the pen drive from host to target when
done...  It makes a slightly a different FAT32 image that
reveals the same issues with fat.c a bit faster.  The part
where it wipes out /dev/sda1 is commented out, so uncomment
at your risk and modify as needed for a SCSI host.

The middle of this message describes how the XP FAT32 image was
made.  The latter part of this message shows the list of files
via XP/Cygwin and a different list shown via U-Boot's fatls.

--- Pen drive used ---

A 128MB USB pen drive with the following partition table
is being used (only one pen drive was used in testing):

# fdisk -l /dev/sda

Disk /dev/sda: 131 MB, 131072512 bytes
8 heads, 32 sectors/track, 1000 cylinders
Units = cylinders of 256 * 512 = 131072 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1        1000      127984    b  W95 FAT32
#

--- XP/Cygwin FAT32 image build procedure ---

(For FLOSS/Linux host, just use the attached mklpen script.)

1) On Linux do:

# dd if=/dev/zero of=/dev/sda1 bs=`echo "32 * 512" | bc`

This is an attempt to reduce the effect of a bad "link" to
unallocated space.  There is _no_ proof that this happens.
(Only null strings and null pointers can now be found here.)

2) On MS Windows XP or similar OS, format (mkfs) partition
   1 with a FAT32 filesystem.

Alternative) On Linux: # mkdosfs -F 32 /dev/sda1

Warning: Linux mkdosfs and XP make different FAT32 images.

3) In a Cygwin bash shell, run the mkpen script with
   cd set to /cygdrive/d (or e, f, g, etc. as appropriate):

#!/bin/bash
for char in 0 1 2 3 4 5 6 7 8 9 a b c d e f g h \
            i j k l m n o p q r s t u v w x y z ; do
        file=;
        for (( index=0 ; index < 8 ; index++ )) ; do
                file=${file}${char};
        done;
        echo "${file}" > ${file}.txt
done

Alternative) On Linux, run the same script.

Warning: Linux vfat fs and XP FAT32 fs code may produce
         different FAT32 images when running this script.

--- Note about building the FAT32 image with FLOSS ---

I also tested the FAT32 image that is built exclusively
via FLOSS tools (using the Linux alternatives in steps
2 & 3 or mklpen).  The result is shown at the end of this
message.

Hi,

Can you try this one?

Revert my last one patch?
It change the test code, before the while. I use your script on a 
Compact Flash and it looks fine for me (under linux).

The scripts in this thread can be used to test the fat32 filesystem. I 
do some tests using Compact Flash
device and this patchs work for me. I would like to know if is a fat 
layer problem or usb layer problem.

[U-Boot-Users] USB SUPPORT & get_vfatname

[Ken.Fuchs at bench.com]

Michael,

Sorry, your latest get_vfatname patch doesn't work either.

FAT16 works perfectly, so the USB code is probably _not_ at fault.  I see only problems with FAT32, but only for _some_ long collections of files.

Thus, there may still be a problem with fs/fat/fat.c.  Maybe there is something wrong with my copy of fat.c  I attached it;  Perhaps you can see a problem with it.

Sincerely,

Ken Fuchs

[U-Boot-Users] USB SUPPORT & get_vfatname

[Ken.Fuchs at bench.com]

My include/fat.h is identical to the fat.h in both
git repository u-boot and git repository u-boot-at91,
except that I put the CHECKCLUST() macro in fat.c
rather than fat.h.

Can you put in debug the fat.c file?
Try to align the temp buffer in fat.c to 32 bit and send to the list
a log file during the fatls command.

To do the align just put the attribute keyword.

fat/fat.c:              __u8 tmpbuf[FS_BLOCK_SIZE] 
__attribute__((aligned(4)));
fat/fat.c:__u8   get_vfatname_block[MAX_CLUSTSIZE] 
__attribute__((aligned(4)));
fat/fat.c:__u8 get_dentfromdir_block[MAX_CLUSTSIZE] 
__attribute__((aligned(4)));
fat/fat.c:__u8 do_fat_read_block[MAX_CLUSTSIZE] 
__attribute__((aligned(4))); 

Your test in my CF card works without problem.

Regards Michael
