Hello,
during my PXA27x USB device support developing adventure I notice that usbtty calls the functions:
udc_init: PXA27x usbd start udc_setup_ep: setting up endpoint addr 0 udc_enable: enable device a2077f74, status 0 udc_connect: udc_setup_ep: setting up endpoint addr 1 udc_setup_ep: setting up endpoint addr 82 udc_setup_ep: setting up endpoint addr 83
Looking at PXA27x manual I read that I have to setup the endpoints and __then__ enable UDC for normal operations! But looking above I see that u-boot calls before the udc_enable() and then the function udc_setup_ep()...
I think that the correct sequence into usbtty should be:
@@ -554,11 +554,11 @@ int drv_usbtty_init (void) usbtty_init_strings (); usbtty_init_instances ();
+ usbtty_init_endpoints (); + udc_startup_events (device_instance);/* Enable dev, init udc pointers */ udc_connect (); /* Enable pullup for host detection */
- usbtty_init_endpoints (); - /* Device initialization */ memset (&usbttydev, 0, sizeof (usbttydev));
Comments?
