Re: ppcboot boot-up question

I have my PPC 750 setup to delay for 5sec then boot
from the DiskOnChip.  This works properly, as long as
I have an active serial connection to the board.
However, I've noticed that if there is not an active
serial connection to the board, the autoboot function
will not work.  If I reset the board, with no serial
connection, then start minicom after 10 seconds I
always find the following:

=> AT S7=45 S0=0 L1 V1 X4 &c1 E1 Q0
syntax error
It seems you configured miniom to send a modem init string.  This  is
not expected by PPCBoot.
Does anyone know what I am doing wrong??
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,

Wolfgang Denk
