You probably need the serial handshake lines properly terminated, or hardware handshaking disabled, so that your boot process isn't waiting for the handshake lines to go active.  For a test, make a DB-9 (or whatever) with RTS connected to CTS and DSR connected to DTR and DCD.  Plug this into your board and I suspect it will boot fine.

The "AT S7=45 S0=0 L1 V1 X4 &c1 E1 Q0" is minicom trying to initialize your modem (which obviously doesn't exist).  This can be ignored, but a better solution is to switch to ckermit (as Wolfgang would strongly recommend ;-) or change your minicom default initialization by deleting all the modem initialization strings.

Subject: ppcboot boot-up question



I'm using PPCBoot 2.0.0
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
=>

Does anyone know what I am doing wrong??
