Well, I've overcome the problem. I was using a GPIO as GND to the ESC. This
was convenient since those pins are next to each other. Once I used true
GND, then the problem went away.
But why would using a GPIO as a GND cause a shutdown? I know it will
restrict the amount of current sinked due

It can print text message (mentioned in code )on terminal. but unable to

can any body please help me?
It all depends on what the ESC current is. The current spec for GPIO
is not a suggestion, but an absolute maximum value; if you exceed it,
all bets are off (reset is actually a polite thing to do---permanent
pin buffer damage can also happen, as well as wider damage to the
chip).

Well, what ever I did, I fixed when I only disabled BB-BONELT-HDM (rather
than both).
Things are working well now. Thanks so much for the help.
