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. gvb > -----Original Message----- > From: owner-linuxppc-embedded at lists.linuxppc.org > [mailto:owner-linuxppc-embedded at lists.linuxppc.org]On Behalf Of Todd > Sent: Monday, February 02, 2004 4:40 PM > To: linuxppc-embedded at lists.linuxppc.org > 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.
