DM814X SPI Flash boot, can not get ethernet support

Hi,

We just finished our customer defined board with DM814X, and verify the UART boot + NFS can work on our board. 

Because we have a large EMMC chip on board, we have to use SPI Flash as the boot up device. So we run into the SPI Flash boot process, and burnt the image. Then the board can boot from SPI Flash properly, but can not get ethernet support in uboot. We tried to ping the host on target board in uboot 2nd stage cmd line, but no response, generally it has response when using UART boot. 

We have tried to compare the UART boot code and SPI boot code, but no finding. So it seems we stuck here for days, any ideas or suggestions? Thanks.

    I've had problem with my own board as well. I trimmed down u-boot so I can keep nand+ethernet into a single stage u-boot, that that work, but all I can get on the network so far is the link working, but no packets get transmitted (or received). Haven't found the reason yet...
