Keith By default on Davinci usb is not built into the kernel but built as kernel modules. Make sure you have the kernel modules corresponding to the uImage your are booting available in /lib/modules and what you are trying to do should work fine (the kernel needs to find the usb device drivers on your file system and it likely cannot currently). For more information on how to install your kernel modules see the Documentation/kbuild/modules.txt file in your kernel source directory. Best regards, Niclas From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Keith Ballard Sent: Monday, October 09, 2006 2:46 PM To: [email protected] Subject: USB port usage Hi, I am
trying to get a USB memory stick to work on the DVEVM board. I have loaded
usb-storage module. When I
insert it, there is nothing reported (also in dmesg).
lsusb just shows mentor grahics device, not my stick.
lsmod shows usb_storage was
loaded. Mount
gives : rootfs on / type
rootfs (rw) /dev/root
on / type ext3 (rw,data=ordered) proc on /proc
type proc (rw,nodiratime) sysfs on /sys
type sysfs (rw) tmpfs on /tmp
type tmpfs (rw) usbfs on
/proc/bus/usb type usbfs (rw) /dev/root
on /dev/.static/dev type ext3 (rw,data=ordered) none on /dev
type tmpfs (rw) devpts on
/dev/pts type devpts (rw) tmpfs on
/dev/shm type tmpfs (rw) I don’t
think any of these correspond to my memory stick (though I may be
wrong). If I try
to mount /dev/sda1, it says mount successful, whether the stick is there or not!
However the contents cannot be accessed. I tried a
USB mouse (I want to use x-windows eventually), also to no avail (I remembered
to load usbhid module). I think I
must be missing something fundamental to USB usage on the board, as nothing
seems to work. Regards, Keith
