在配置serdes和sgmii按照公式refclk = LINERATE * RATESCALE/MPY
EVM板式156.25=1.25g*2/16
自己的板子refclk 为125Mhz
需要将mpy值从16改成20,请问关于mpy这个寄存器SGMII_SERDES_CGFPLL的地址
以及在uboot中如何修改的?

您好,我使用的是K2e的评估板,运行的是masdk中的hello world例程,我运行后出现
Registration of the EMAC successful,waiting for link up ..
Service status:DHCPC :Enables : :000
Service status DHCPC :Enables: :000
此后,console中就再也没有任何提示,程序一直在运行,不会自动停止。相关的寄存器中是error,无法读取。
请问,我需要修改哪些参数,才能正确运行程序,传输数据?
此外,如何修改DSP的IP配置模式(DHCP 或是手动)?
谢谢,期待您的回答
