Hi,
I'm can build the 4.14.98_2.0.0 uboot-imx repo fine for iMX8QM MEK using (no changes):
make imx8qm_mek_defconfig
make CROSS_COMPILE=/opt/toolchains/gcc-arm-9.2-2019.12-x86_64-aarch64-none-elf/bin/aarch64-none-elf- V=1
When I load uboot via eMMC flash :
sudo ./uuu/uuu -b emmc_all imx-mkimage/iMX8QM/flash.bin fsl-image-validation-imx-imx8qmmek-20200607014211.rootfs.sdcard.bz2/*
and stop autoboot as follows I see a waning "No ethernet found":

Can someone share what could be wrong on interrupting autoboot for TFTP ?
I used uboot-imx/tools/gen_eth_addr to set ethaddr, set ipaddr and serverip env vars and saveenv. But no change in behavior when I interrupt autoboot.
If I allow the Linux kernel to fully boot, I can set the IP address and ping a TFTP server fine.

What is missing before autoboot ? Thanks for help.
