Hello,

I get m8xxhci.c last release form = Brad=20 Parker's page
http://www.heeltoe.com/usb/ppc <http://www.heeltoe.com/usb/ppc>  and I=20 have
modificated to use on the MPC823 FADS board. This drivers has = also=20 Roman
Weissgaerber changes.

I have done the following=20 modifications:

1.- At the begin of the file:

#ifdef = CONFIG_MYBOARD=20
#define=20 USE_PA5_CLK3_USBCLK         =      =20 /* 48mhz clock via clk3 */
#define=20 USE_TIMER1_FOR_SOF
#endif

2.-I have loaded the microcode patch.

3.-I = put=20 TIMER 1 output (PA6) in the DRQ0 input and connect it to=20 PC15

After booting Linux I have the following = mesages:

........
m8xxhci: initializing=20 controller
m8xxhci_setup()
usb.c: new USB bus registered, assigned = bus=20 number 1
m8xxhci_start_controller()
m8xxhci: USING CLK2 for USB=20 clock!
m8xxhci: ring sizes: rx 60, tx 10
size 0x18 index = 0xa00
size=20 0x1e0 index 0xa38
size 0x50 index 0xc20
PQUCODE: USB SOF patch=20 installed
m8xxhci: enable USB = controller
m8xxhci_timer_setup()
m8xxhci:=20 timer bytes/count 0.25
m8xxhci: USING TIMER1 FOR SOF!
m8xxhci: = timer1=20 started
m8xxhci: usb bus is NOT idle
Product: USB MPC8xx Root=20 Hub
SerialNumber: ff000a00
hub.c: USB hub found
hub.c: 1 port=20 detected
rh_submit_urb() int pipe
rh_port_power(1)
m8xxhci:=20 initializing done

and when i connect a device=20 ............

 idle_bus() 1; d+ zero, d- one, connect = lo-sp
rh_port_reset(1)
hub.c: new USB device m8xxhci-1, assigned = address=20 2
usb_control/bulk_msg: = timeout
unlink_urb(urb=3Dc0552f50,qtype=3D2) status=20 -115
unlink_urb(urb=3Dc0552f50) done
usb.c: USB device not = accepting new=20 address=3D2=20 (error=3D-110)
m8xxhci_free_dev(usb_dev=3Dc049d600)
m8xxhci_free_de= v(dev=3Dc049d600)=20 done
rh_port_reset(1)
hub.c: new USB device m8xxhci-1, assigned = address=20 3
usb_control/bulk_msg: = timeout
unlink_urb(urb=3Dc0552f50,qtype=3D2) status=20 -115
unlink_urb(urb=3Dc0552f50) done
usb.c: USB device not = accepting new=20 address=3D3=20 (error=3D-110)
m8xxhci_free_dev(usb_dev=3Dc049d600)
m8xxhci_free_de= v(dev=3Dc049d600)=20 done
rh_port_enable(0)
..............


may i = ask you a=20 few questions about m8xxhci.c driver :
1) what=20 do the define POLL_FOR_HUB   stands for and should i = use it=20 ?

2) is it correct to include hcd.o + hub.o +  usb.o + = usb-debug.o=20 to make
usbdrv.o in the kernel ?

3)Is the behavior of the driver correct according to the trace = above if=20 no
data goes out of MPC885 USB pins ? What can prevent data to go out = ?

4) is it correct to include your driver in the kernel ? (and = not run it=20 as
an external module) ?

5) i try this driver with SOF = generated by=20 micro-patch :
-> should this SOF automaticaly sent on the PPC usb = tx data=20 line as soon as
a device is connected ?
-> when you plug a usb = device=20 (keyboard) what is the first thing the driver
must do ? send a setup = command=20 ? (I try to see when you write this command
in a BD but i can't find = it=20 )

6) can this driver drive mass storage device (selected by=20 CONFIG_USB_STORAGE
kernel parameter) ?


76) when we use = USB_UPATCH=20 how do behave the CPM ? does it generate SOF
continuously ? how do we = tell=20 the CPM to start or stop the SOF transmission
?

Thank you very much for any reply
Best = regards
