It seems you configured miniom to send a modem init string. This is
not expected by PPCBoot.

You use minicom.
You post to the wrong list (u-boot-users is a much better place for
such questions).
You don't provide any details. Maybe the serial driver on your board
is waiting for a hardware handshake signal (DCD?) which is down while
disconnected? What happens when you disconnect the cable?
Best regards,

succeeded in creating a generation of users who don't understand the
concept of a shell...
