You need to start by writing a USB device driver for that chip. See
the eCos USB documentation.

Hi Andrew,

The USB 1.1 interface on ADI board is built around the on-chip USB
controller and can work only as the USB peripheral at 12 Mbps data rate.

Is the driver already available for the in build USB of IXP425?

Regards,
Navya

Not that i know of which is why i said you need to write a driver.

Hi,

I created a driver package for USB on IXP425. I have modified the ecos.db to
include the USB package. Similarly I have edited the .ecm files for the
board. But while compiling the image the driver source is not compiled.Is
there any other change to be made?

Please help

Navya

Nope. 

The linker may through the driver away if it is not used, but you say
it is not even being compiled. So this is a different issue. Does your
packages CDL have any enable/disable logic? Does you ecos.ecc file
contain the driver package and any options it make include. Do you get
a makefile for it in the build tree? Does the Makefile list the source
file?

Hi,

I have the code compiling now. The cdl_option for EP0 was taking the default
value of CYGINT_IO_USB_SLAVE_CLIENTS which was 0.I changed this value to 1
with this the USB code gets compiled.

Thank you so much for the information.

Navya

What protocol are you running on top of the USB driver? What
enumeration data do you provide? If you run lsusb do you see the
device on your host?

Hi,

I could successfully compile the redboot with USB drivers for IXP425, but
when I load the image I am not able to get the initialization code running.
I have enabled the diagnostic message in the USB in usbs_ixp425_init ()
function which is the entry point. How can I proceed? Please help

Navya

[ECOS] How to enable USB on IXP425 GRG

[Navya S Kamath]

Hi,

I am using ADI Coyote Residential Gateway Reference Design based on Intel
IXP425 network processor. I would like to enable the USB device on the
board. How can I do this? 

Currently when I connect the USB on the board with a windows XP based PC
Windows says that "USB device attached has malfunctioned and windows does
not recognize it".

How can I get the USB up and windows recognize it? Please help.

Regards,
Navya
