BBB issue for booting with sd-card

Hello all,

As i am new to BBB angstrom environment i thought of using ezsdk from ti for am355x. I have downloaded the latest version “ti-sdk-am335x-evm-” and followed the procedure from the below link

The issue is i cannot see the uboot prompt in minicom console even though i have configured minicom with 115200 8N.

When i power up BBB with sd-card inserted i found an boot window poped out after few seconds which contain uImage, u-boot.bin, MLO.

Can any one suggest me how to proceed further.

Thanks & Regards
