TI中文支持网8168如何通过网口1（DEMO板默认是网口0）下载UBOOT？
TI的DEMO板上面默认的是使用网口0，如果要想从网口1来下载，请问要修改哪里？怎么修改？
Eason Wang：
Hi Eason,
In the DM816x TRM, chapter 25 ROM Code, I can see that only EMAC0 (GMII0, CPGMAC0) is supported for boot by the ROM code.
25.5.2.1 MBOOT Configuration Pins
The following shortcuts are used in the table:Ethernet Ethernet GMII0 interface (EMAC port 0)25.8.4 Ethernet Boot ProcedureEthernet boot uses the CPGMAC0 subsystem of the device, connected to external Ethernet PHY using the GMII0 and MDIO pins.Table 25-24. Pins Used for Ethernet Boot – GMII0 pins

回复 Eason Wang:
我指的不是从EMAC1启动，只是从EMAC1下载UBOOT而已，现在已经知道答案了，谢谢Eason Wang
