Re: [ECOS] AT91SAM7SEK and USB-SLAVE

[wavecom wavecom <wavecomw@yahoo.com>]

IÂ’ve created test USB package (only package
directories and definition without any C-code).
testusb.cdl looks like below:
“
cdl_package CYGPKG_TEST_USB {
    display       "Test USB"
    description   "Test USB"
    implements  CYGPKG_IO_USB
    implements  CYGPKG_IO_USB_SLAVE
    implements  CYGINT_IO_USB_SLAVE_CLIENTS 

    cdl_component CYGPKG_TEST_USB_DEVICES {
        display       "Test USB dev"
        flavor        bool
        default_value 1
        description   "Test USB dev"
    }

}
“.
Next IÂ’ve added the package to ecos.db and to my
project. But still, when I’m trying to enable “Support
the control endpoint 0”, I’ve got conflict “… requires
CYGPKG_IO_USB CYGPKG_IO_USB_SLAVE”. 
To solve that, I’ve tried to add “USB slave-side
support” and “USB Support” but the configuration tool
rejected that, because of hardware property.
Do I need to add these two packages?
How to solve CYGPKG_IO_USB CYGPKG_IO_USB_SLAVE
problem?
IÂ’m used at91sam7sek template.
