Subject: [U-Boot-Users] USB OHCI issue
Date: Tue, 29 Nov 2005 18:19:28 +0100 [thread overview]
Message-ID: <438C8DA0.8060600@rfo.atmel.com> (raw)
Hi all,
I am trying to port usb_ohci code (u-boot-1.1.3 version) from
cpu/arm920t/s3c24x0 to our chip.
I added low_level specific functions and It seems to work correctly with
a low
speed device (mouse...).
Things get a little more compilcated when I use a disk-on-key.
when I perform a : usb start
U-Boot> usb start
(Re)start USB...
USB: scanning bus for devices... 2 USB Device(s) found
scanning bus for storage devices... ERROR: CTL:TIMEOUT

Device NOT ready
Request Sense returned 00 00 00
0 Storage Device(s) found
But when I perform a usb tree I get this :
U-Boot> usb tree
Device Tree:
1 Hub (12MBit/s, 0mA)
| OHCI Root Hub
|
+-2 Mass Storage (12MBit/s, 94mA)
M-Sys DiskOnKey 2730C3409173AB63
or a usb info :
U-Boot> usb info
1: Hub, USB Revision 1.10
- OHCI Root Hub

2: Mass Storage, USB Revision 2.0

Interface: 0

- Class Mass Storage, Transp. SCSI, Bulk only
- Endpoint 1 In Bulk MaxPacket 64
- Endpoint 2 Out Bulk MaxPacket 64
But when I perform a usb storage I get this :
U-Boot> usb storage
No storage devices, perhaps not 'usb start'ed..?
Do you know why all this mess around the disk-on-key ?
Do you know how to solve this ?
Should I try code from cvs instead of that of 1.1.3 version ?
Best regards,
Amine.
