[U-Boot-Users] PXA27x USB support?

[David Snowdon]

G'Day,

Has anyone given PXA27X USB support a go? If not, I'm probably going  
to need to have a crack. Anyone else have a need for it? Any sage  
words of advice from someone who's looked at USB for another platform?

Cheers,

Dave.

In my PXA270 Mainstone U-Boot port, it has not been required,
neither implemented, but I never needed USB in bootloader.

Not exactly the PXA27x but its successor monahans, which is more or less
identical regarding usb. I started of from the arm920t s3c24x0 usb_ohci
driver and it required few changes such as modifying the OHCI base
register and clock setup to compile and detect the root
hub. Unfortunately I couldn't do any further testing so far due to lack
of HW.

I have the same problem for a MIPS CPU. My driver starts from arm920t
one and also my drive recognize the Root hub but not the USB
devices...

I think the problem is on the driver itself instead of the several
platforms port. :)

Ciao,

Rodolfo

[U-Boot-Users] PXA27x/Au1x00 USB support?

[Rodolfo Giometti]

Hello,

using an USB traker I see that the USB driver do _not_ send any
packets on the bus, neither the ?setup? one!

Also I noticed that if I enable the periodic list (OHCI_CTRL_PLE) the
controller sends some OUT packets even if the periodic list descriptor
are 0!

I think that the driver wrong initialize the USB host...

Ciao,

Rodolfo

[U-Boot-Users] PXA27x USB support?

[David Snowdon]

Unfortunately a client wants to be able to have sealed connectors on  
their custom PXA270 board, which isn't possible with CF or SD, etc,  
but is with USB. They want to be able to field upgrade the devices by  
giving the technicians a USB stick, sending them around to the  
devices and pressing the reset button.

Thanks Markus and Rodolfo for you thoughts! I'll give it a go and  
submit a patch.

Cheers,

Dave.

You are well come.

However I think it could be a good idea to put OHCI support into
?common? directory (the new file can be called ?usb-ohci.c?) and then
exporting into it some hooks for several platforms whose wish use it.

You are right. Please feel free to submit a patch.

The usb boot function does not work well in my target platform pxa27x,so i
hope you can forware your patch to my mail box.

Please beware that the USB-support in the cpu/pxa directory of the
testing-USB branch is only tested with the monahans cpu, and will
possibly not work for pxa27x out of the box.
