5.4.13 eTSEC & BCM5482
COMX-P2020 provides three enhanced three-speed Ethernet controllers (eTSECs) which
interface to 10 Mbps, 100 Mbps, and 1 Gbps Ethernet/IEEE 802.3™ networks. 2 BCM5482 was
used to connect with eTSECs through RGMII. Each BCM5482 can provide 2 ethernet
transceivers designed for 1000-Mbps, 100-Mbps and 10-Mbps application. The Phy Address for
the eTSECs are list below:
eTSEC0 : phyID = 0
eTSEC1 : phyID = 2
eTSEC2 : phyID = 1
The U-boot provides standard command "mii" to probe, read and write BCM5482 register. This
part is not included in this document.
=> help mii
mii - MII utility commands
Usage:
mii device - list available devices
