MPC8360E USB Host Controller Driver

MPC8360E USB Host Controller Driver

[n.balaji]

Hi All,
   I am working in MPC8360E processor board. I want the PowerQUICC II's
Pro  USB Host controller Driver. In the manual, they told that this
controller does not belong to UHCI or OHCI standard.

  I have doubt that whether Freescale has its own USB standard.

  Please give the link or patch for that driver.


Thanks,
N.Balaji

Yes, you can call it FHCI if you like. :)

The interface is stated clearly in the UM.

There is an 8360 host driver in Freescale LTIB BSP.  Please find it on
www.freescale.com, if it has been released.

I heard that on the PQII (82xx) devices the FHCI required
intervention from the core, even when there was zero traffic
on the USB.  I think this was because the core had to
continuously service a 1ms interrupt.  This generates significant
extra loading, making it worth considering using a cheap EHCI chip
instead....

Does anyone know if this is still the case with the PQII Pro (83xx)?

Hi all,

i have a MPC8347E running with the Freescale E(F)HCI driver and Kernel =
2.6.17 (Freescale LTIB).

Because of this mail, i checked, if there are any periodical interrupts, =
without real USB payload.

The result is: NO

If i attach a USB-mouse, i get 5 interrupts.
If i remove it again, 1 additional.

Nothing else, silence !

USB works well with USB 1.1 and 2.0 devices=20
(This was not the case with earlier Kernels, e.g. 2.6.13, because for =
the switching between 1.1 and 2.0 you need a transaction translator =
driver).

There are improvements on future chips with a QE.  However it is still
full-speed and need CPU intervention.  But keep in mind that USB is not
a key feature for netcomm devices which PQ is targeting.

834x has a integrated EHCI controller instead.

MPC834x USB is very different from the USB of CPM/QE.  It is an
integrated EHCI controller.

Could you give a direct link ? I've been browsing around the Freescale website 
for an hour, downloaded hundreds of megabytes of archives but haven't been 
able to find the MPC8360E USB Linux driver.

So, the question is still open, does the QuiccEngine HCI (a.k.a. FHCI)
generate loading on the PPC core when there is no traffic on the USB?

Yes, but no.  If the bus is idle for some time, you can put the bus
into suspend state.  Then there will be no extra load to the core.

Is that what Freescale's linux driver does then?

Can it detect new USB devices in suspend state?

Hi Laurent,

I believe that I recall seeing the USB drivers in the "MPC8360E Device
Drivers - Release 1.1 GPL ", accessible from the main 8360 page.

http://www.freescale.com/files/netcomm/software/device_drivers/MPC8360EGPLDRV.zip

One little gotcha... When you unzip this archive, it's a windows
executable, but it doesn't have the '.exe' extension on the file, so
you'll need to add it by hand.  I had to "contact my local FAE" just
to figure out that one when the darn thing wouldn't run.  Too many
years of using Unix I guess.

No, rest assured, you're not.  Try finding any information about the
eval board for the 8360 on freescale.com.

These don't look like Linux drivers to me.  (Although they are GPL so you could
port them to Linux if you have the inclination.)
