Hi,
SDK: ti-processor-sdk-linux-am57xx-evm-06.03.00.106-Linux-x86-Install.bin
Customer want to boot kernel by tftp.
1. Make MLO/UBOOT.img
board-support\u-boot-2019.01+gitAUTOINC+333c3e72d3-g333c3e72d3：
make CROSS_COMPILE=arm-linux-gnueabihf- distclean
make CROSS_COMPILE=arm-linux-gnueabihf- ARCH=arm am57xx_evm_defconfig all
2.Copy MLO/u-boot.img to SD card boot partion
3. Set the network parameters, then ping the host
=> ping 192.168.1.105
ethernet@48484000 Waiting for PHY auto negotiation to complete................. TIMEOUT !
ping failed; host 192.168.1.105 is not alive

board_name=beagle_x15
if test $board_name = beagle_x15; then setenv fdtfile am57xx-beagle-x15.dtb
He want to use am57xx_evm.dts and there is no am57xx_evm.dts in arch\arm\dts
Will the incorrect dts file cause uboot to fail to ping the host?
