Hi Anil
I'm also facing the same issue. Once my BBB board works fine with my AC charger(5V, 2A). When i connect with UART-USB Debug cable (TTL-232R-3V3) with my BBB means it doesn't boots up properly and the user LEDs were doesn't blink and also my minicom prompt (not responding )show some junk characters.
KIndly see my link:http://e2e.ti.com/support/arm/sitara_arm/f/791/t/346499.aspx
If you get any ideas kindly share with me.
Thanks
Roven
