[ECOS] How to enable USB on IXP425 GRG

[Navya S Kamath]

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

Regards,
Navya

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.

Regards,
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?
