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()...
There are something wrong or I haven't understood well how UDC support
works? =:-o
Thanks,
Rodolfo
