Clear out your eMMC, you have a really old build of u-boot installed
to eMMC that is blocking your new image..

Yes, I even had that mentioned in the corresponding README:
http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto/tree/meta-yocto-bsp/README.hardware#n134

HI Denys / Robert ,

Thanks , got the board boot up now.
Followed below mentioned steps ( just in case if any one face similar
problem )

1) Erase the MMC
    => mmc dev 1
    => mmc erase 0 512

2) Install TFTP server on host
https://askubuntu.com/questions/201505/how-do-i-install-and-run-a-tftp-server

3) Transfer the dtb & zImage
=> setenv gatewayip 192.168.1.1
=> setenv ipaddr 192.168.1.2
=> setenv serverip 192.168.1.3
=> ping 192.168.1.3
 => tftp 0x82000000 zImage
=> tftp 0x88000000 am335x-boneblack.dtb
=> bootz 0x82000000 - 0x88000000

Thanks
Ashish
