4.2 Ethernet port map
The table below shows how Ethernet ports match to Linux, U-Boot, and the front-panel
label on the 1U box.

ETH3 Not supported in U-Boot 0xfe4e0000 L2 switch
ETH4 Not supported in U-Boot L2 switch
ETH5 Not supported in U-Boot L2 switch
ETH6 Not supported in U-Boot L2 switch
ETH7 Not supported in U-Boot 0xfe4e2000 L2 switch
ETH8 Not supported in U-Boot L2 switch
ETH9 Not supported in U-Boot L2 switch
ETH10 Not supported in U-Boot L2 switch
1. Connected to L2 switch port at 2.5 Gbit/s. This port cannot be connected to external PHYs, as T1040RDB supports only
SerDes protocol, 0x66
NOTE
ETH3-ETH10 belong to the switch. They are not visible as
interfaces in Linux. Switch control software is required to
control them.
4.3 NOR flash image layout
NOR flash can be divided into two flash banks (0 and 4) to store a main image and an
alternative backup image. This is shown in the below table.
