Hi Sarah,
many thanks for your answer, reading again my confused message
I understand that you must be a much, much clever girl, I mean,
your surname speaks for itself :-)
let me explain better this time:
-first of all, I work as an Embedded Linux consultant
on a prototype board with a Texas Instruments TI8168 device
(brief data sheet here: http://focus.ti.com/lit/ds/sprs614/sprs614.pdf)
-the PCIe controller embedded into TI8168 is connected
to the (TI again) TUSB7320 2-ports xHCI-compliant USB3 controller
(data manual here: http://focus.ti.com/lit/ds/symlink/tusb7320.pdf)
-TI delivers a complete TI81XX SDK covering all the (many) onboard cores:
the ARM Cortex-A8 is supported via patching Linux Kernel 2.6.37
basicly with the TI8168 chip support and the TI EVM board support,
PLEASE NOTE that the drivers/usb subtree has NOT been patched in any way
-I ran ‘make menuconfig’ after selecting my boards’ defconfig,
adding the following lines:
CONFIG_USB_DEBUG=y
CONFIG_USB_XHCI_HCD=m
CONFIG_USB_XHCI_HCD_DEBUGGING=y
-my runtime routine is to prevent autoloading xhci-hcd.ko via blacklisting
and load it later via modprobe, I don’t know if this helps, anyway
now, among the various issues I raised in the previous email,
I would like to focus on what I think is the major problem: the random crash
that happens with NO (!!!) USB peripheral plugged in
(BTW ‘gadget’ is the misleading term I used in place of ‘peripheral’)
please find attached a single TXT file with three sections of dmesg dumps:
-the first one refers to when I load xhci-hcd.ko via insmod
-the second one appears randomly and looks like an activity report from
the hub;
-the last one is the crash itself, an illegal access at location 0x00001008
which is not addressable by the ARM processor
looking forward from some hints, best regards,
Francesco

Hi,
looking for people having trouble with TUSB73x0? Here I am :-)
Hi Francesco,
(It helps if you send mail directly to me along with Ccing the linux-usb
mailing list. :)
actually, I'm using a TUSB7320 (just two less ports away from 7340),
plus Linux Kernel 2.6.37 with TI proprietary patches
(I'm working on a board hosting a TI81XX system-on-chip)
So what are these proprietary patches and how did you get them? Do they
apply to the xHCI driver, or to some other in-kernel driver, or did TI
give you a binary module to install?
here's what happens:
- hotplugging USB2/USB3 peripherals is ineffective,
the only way to have a gadget seen is plug it BEFORE powering on
Ok, that sounds like a hardware problem, probably around link training.
- moving files from a gadget (a WD My Passport 500GB HD Drive)
By gadget, I assume you mean USB device? We use gadget specifically for
devices that run Linux (e.g. a Linux gadget or a gadget driver).
to central mass storage works, moving the opposite way don't
ends up in a filesystem error, and the device gets unmounted
So writing to the device causes a filesystem error. Can you send the
dmesg?
- same things as before if I plug the same HD through an USB2 hub
Does the device work if you plug it into another USB port on the same
machine (an EHCI port)?
do you know if TI is supporting linux directly on these devices?
The TI xHCI host controller should just work with the xHCI driver. I'd
have to see the dmesg of the failure to confirm that the driver isn't
doing anything wrong, of course.
and of course, Sarah, do you have some hint?
Send me your dmesg and I might find a hint there. Otherwise, no, I have
no hints for you. :)
