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

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 :

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.
