<div class=WordSection1>
<p class=MsoNormal>I am trying to bring up a P2020 board which uses the
Broadcom BCM53115 switch in unmanaged mode. The board is patterned after
the P2020RDB, except the Vitesse switch has been replaced with a BCM53115. There
is no MDIO connection to the switch, but there is an SPI connection
available if needed.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>When running Uboot, the BCM53115 works just fine, as I am
able to download the Linux Kernel and P2020RDB.dtb across the network without
issue. But as Linux is booting up, I get the message:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>mdio_bus mdio@ffe24520: error probing PHY at address 0<o:p></o:p></p>
<p class=MsoNormal>mdio_bus mdio@ffe24520: error probing PHY at address 1<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I expect these errors occur because the P2020RDB.dts file
has these entries.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m not sure what to try next to get Linux to use the
BCM53115 switch in unmanaged mode.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any help is appreciated,<o:p></o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
