[U-Boot-Users] USB OHCI issue

[U-Boot-Users] USB OHCI issue

[Matthias Fuchs]

Hi everybody,

I am currently playing around with U-Boot's (PCI) OHCI driver
on a 405 board. U-Boot's USB stuff is running fine on this board. I can
read files from an USB stick without any problems.

But when I start Linux with a (rather old) 2.4.21 kernel, the still connected USB
stick is not detected as storage device. I have two ways to get USB working 
under this Linux kernel:

a) I do not start the USB subsystem at the U-Boot prompt ('usb start')
b) I disconnect and reconnect the USB stick when Linux is running.

Both options are not really what I want.
Calling 'usb stop' before booting Linux does not help.

I am not sure if this is a Linux or U-Boot issue. Perhaps a newer kernel does not
show this issue, but upgrading is currently not an option:-)

Can anybody verify this behavior with other 2.4.x kernels? 

Regards
Matthias

So maybe USB does not get stopped completely when "usb stop" is
issued. Are you using the generic USB driver (CONFIG_USB_OHCI_NEW) ?
Maybe you need some board dependant code to correctly stop USB?

> b) I disconnect and reconnect the USB stick when Linux is running.

So the kernel doesn't get notified of the already plugged device if it
has been started under U-Boot. I suppose this supports the theory of
"usb stop" not working.

I would try to find why :-)

Hi Wolfgang,

CPU is OMAP2420. USB host controller is integrated in this CPU.

[Zhang Wei]

Do you usb CONFIG_USB_OHCI_NEW?
Do you try to add "#define CFG_OHCI_SWAP_REG_ACCESS	1" to your config file?

[U-Boot-Users] usb ohci issue

[Wang, Steven]

Yes, I define CONFIG_USB_OHCI_NEW in my config file.
My usb controller is not PCI controller. So, I did not define CONFIG_USB_OHCI_NEW.

[U-Boot-Users] usb ohci issue

[Zhang Wei]

CONFIG_USB_OHCI_NEW is not only for PCI USB controller. The interrupt transaction support is added into OHCI_NEW driver. If you want to enable USB keyboard support, you should use OHCI_NEW driver. If your controller need swap register, please add "#define CFG_OHCI_SWAP_REG_ACCESS	1".

Cheers!
Wei.

[U-Boot-Users] USB OHCI issue

[Mohammed Amine SAYA]

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

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)

No storage devices, perhaps not 'usb start'ed..?



Do you know why all this mess around the disk-on-key ?
