I'd rather remove the unused drivers from the configuration,
then have them built-in and do something with the missing hardware...

It states: "ISP1105BS(DNP)" - is it assembled at all?

Indeed, those are the defines, but you need to do the actual configuration
for them, by calling pxa3xx_mfp_config() with appropriate parameters.

Hi, Igor and all,
Thank you very much for giving me such valuable help.
Now I have upgrade the ohci part (drivers/usb/host/ohci-pxa270.c ..)
to 2.6.29. (I am failed on upgrade the total branch from 2.6.27 to 2.6.29 :( )
But the problem still exist.
(the isp1105 was really assembled; and the GPIO pins are initialized with
pxa3xx_mfp_config() ).
when I insert a usb-disk, it output
-----------------------------------------------------------------------------------------
usb 1-3: new full speed USB device using pxa27x-ohci and address 2
usb 1-3: device descriptor read/64, error -62
usb 1-3: device descriptor read/64, error -62
usb 1-3: new full speed USB device using pxa27x-ohci and address 3
usb 1-3: device descriptor read/64, error -62
usb 1-3: device descriptor read/64, error -62
usb 1-3: new full speed USB device using pxa27x-ohci and address 4
usb 1-3: device not accepting address 4, error -62
usb 1-3: new full speed USB device using pxa27x-ohci and address 5
usb 1-3: device not accepting address 5, error -62
hub 1-0:1.0: unable to enumerate USB device on port 3
----------------------------------------------------------------------------------------
and dmesg shows this info continuesly.:
hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0000
hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0000
...
hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0000
a detailed log file is attached.
Is there any hardware problem?
maybe the connection of ISP1105 was wrong.
and I found the VCC voltage is only 3.0v, it is lower than 3.3v
(in the spec). Is this a fatal issue?
Thank you very much!

Indeed, this can be a h/w problem.

May be not fatal, but could bring issues...
I'd check the VBUS on that usb port and also the pull ups on DP/DM.
If those are not by the spec. then the chances of getting it work are poor.

The host USB transceiver (ISP1105) should have external 15K pull-downs
on both DP and DM. The device will have a pull-up on one signal to
distinguish low speed vs. full speed.
You didn't mention what USB device you're test with. Is it actually full
speed as the kernel logs indicate?
Do you mean VCC on ISP1105 is only 3.0V? That's the minimum, so it may
still be functional. Hopefully the supply is adjustable.
ISP1105 supports both single-ended and differential input modes, as
selected by the ISP1105's MODE pin. Can you confirm the PXA310 is set
for the right mode? That'll be (digging thru the Dev Man) the P3SS bits
in the U2DP3CR register in the U2D (Yes, the USB 2.0 Device Controller
must be configured to use the USB Host Port 3. Thanks, Intel.) There's
other important settings there, can't think of them off the top of my
head. If that doesn't help, I'll share some code when my PXA310 box
comes back online.

cm-x300 uses PXA310 usb port 3 in host mode (the code is in mainline).
I've already mentioned the U2DP3CR register in one of my previous replies.
On cm-x300 we use 6-wire single ended transceiver (TUSB1105) and
the port works just fine without any special setup (the default values of
U2DP3CR are fine).
So there indeed could be a mismatch between the port configuration (U2DP3CR)
and the ISP1105's MODE pin wiring (although I think "grounded" is 6-wire s/e),
or the pull ups on DP/DM or VBUS or the VCC to the transceiver.

Hi, Experts!
I am debuging some issues on an arm-arch board.
now, I have to compile the whole kernel, download zImage to the target board
and reboot the board again and again. Since the relations between the
source files are complex, it is difficult to just write a module for insmod/rmmod.
My question is: is there any way to boot the kernel from NFS? so we can
use zImage on the host machine through an ethernet/USB cable. Then we needn't
download the zImage file to the target board when we debug it.
Is there any bootloader with this feature? Any comments?
(now I use bootloader LK("Little Kernel"))
Thank you!
Wenjie

U-Boot can download the kernel over TFTP.

Yes, you can use the tftp or bootp command under u-boot. Use "help
<command>" for syntax. Alternatively, you can edit /etc/dhcpd.conf on
the host machine and restart dhcp server to load the kernel
automatically.
