For starters, we'd need to see your uEnv.txt file. After that, while it is possible to troubleshoot an issue like this without a serial debug cable( I've done it, and it is not any fun ). You'd have to be very meticulous, and know exactly how the process works completely.
Anyway here is a link to a guide I wrote a couple years ago: http://www.embeddedhobbyist.com/2013/06/beaglebone-black-network-boot/ Keep in mind that zImage should now work, so everything pertaining to uImage needs to be changed, or ignored( in the case of mkimage ). Just a note though . . . You *need* flash media ( sdcard / eMMC ) anyway, for MLO and uboot.image . . . so I figure what does it hurt to boot the kernel off flash media, and just load the rootfs from NFS ? Anyway, this is what I do now days myself, so have not personally bothered with TFTP boot since I wrote that guide.
