Hi Deval, What code do I need to add to try your test?
I am using the items git head kernel, and your rtems-libbsd RaspberryPi_USB branch. When I run init01 on my Pi Zero, I get the output below. Alan *** LIBBSD INIT 1 TEST *** nexus0: <RTEMS Nexus device> bcm283x_dwcotg0: <DWC OTG 2.0 integrated USB controller (bcm283x)> on nexus0 usbus0 on bcm283x_dwcotg0 usbus0: 480Mbps High Speed USB v2.0 uhub0: <DWCOTG OTG Root HUB, class 9/0, rev 2.00/1.00, addr 1> on usbus0 Sleeping to see what happens uhub0: 1 port with 1 removable, self powered > On Jul 11, 2016, at 10:37 AM, Deval Shah <deval.ma...@gmail.com> wrote: > > Hello all, > > I am trying to add usb_ethernet (smsc) driver for raspberry pi for both USB > and Ethernet support. > Now I have added the required files.
