Does it work because > the default clk speed is 192Mhz? On beagle board the PHY is connected differently, i.e. as the clock receptor. The PHY clock comes directly from the USB_CLK pin. On Panda the PHY is the clock provider to the USB_CLK pin. For that it needs a reference clock at the REFCLK pin which comes from FREF_CLK3. > >> generator in the device tree in PATCH 11.
