I?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 I?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?
I?m used at91sam7sek template.
