Hi:
The Platform we are working are DVRRDK4.01. TI8148-GP rev 3.0
When we debug the uboot, I found it can't use tftp.
At first , we use uart transmit the uboot stage1 and stage2, it started ok but when use ping cmd, it commit some problem and print the host is not alive.
It seems like the ethernet interface appears to can not work in u-boot.
The print information as following picture show:
The design we used are based on the DM8148 and a ET1011T Gigabit PHY.
The interface of PHY we used GMII mode to MAC0.
I checked the uboot code and modified some place:
1.
#if 1
//set to GMII mode LPW 20141119
__raw_writel(0x300,GMII_SEL);
#else
__raw_writel(0x30a,GMII_SEL);
#endif
2 . changed phy_id but no use, 8148 can read ET1011'is phy_id 0x281F014 by MDIO

3. pin_MUX check
the orginal code used a MII/RGMII mod , the setting of MAC0 pin is same as GMII..
But it cann't ping .....
Look forward to some advices....
Thanks
