[ECOS] AT91SAM7SEK and USB-SLAVE

[ECOS] AT91SAM7SEK and USB-SLAVE

[wavecom wavecom]

Hi,

I'm trying to configure usb-slave with the AT91SAM7SEK
template. So I've enabled USB and “Atmel AT91 USB
Device Driver“ and “Support the control endpoint 0”.
But in conflict list I've got that
CYGFUN_DEVS_USB_AT91_EP0 Requires CYGPKG_IO_USB 
CYGPKG_IO_USB_SLAVE. So I 've found a patch:  “
http://www.mail-archive.com/ecos-patches@ecos.sourceware.org/msg00355.html
“. I was trying to patch the usbs_at91.cdl,  but  in
my  usbs_at91.cdl (# Date:           2006-02-25)  is “
       default_value CYGINT_IO_USB_SLAVE_CLIENTS” just
like in + in the patch 
“
-        calculated    CYGINT_IO_USB_SLAVE_CLIENTS
+        default_value CYGINT_IO_USB_SLAVE_CLIENTS
“
How to solve the usb-slave problem?


Pete

What it is trying to tell you is that there is no client software
using the USB, so there is no need to compile the USB stack. So it
does not compile it.

You either need to include/write a package which uses the USB package
and implements the CDL interface CYGINT_IO_USB_SLAVE_CLIENTS, or you
need to set option CYGGLO_IO_USB_SLAVE_APPLICATION and you application
code can the use the USB slave functions.

Can you recommend me a code example of USB on eCos for
the AT91 or other controller?

Re: [ECOS] AT91SAM7SEK and USB-SLAVE

[wavecom wavecom]

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.

Either use the CLI tool ecosconfig which ignores the hardware
property.  Or add CYGPKG_IO_USB and CYGPKG_IO_USB_SLAVE to the
at91sam7sek target in ecos.db.

Another AT91 USBSlave question :):) :
File:
ecos/packages/devs/usb/at91/current/include/usbs_at91.h
contains only usbs_control_endpoint and 3
usbs_rx_endpoint.
How to retrieve proper instance of usbs_tx_endpoint?

Thanks,
Pete
