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

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??
