That's your hint.
"no USB device"
Check:
- is the autopilot connected to the USB before you give it power? It's only on
power on that P0.23 checks for 5v from the USB. If you connect the USB after
powering on the board P0.23 is not checked and the LPC is not going to go into
USB boot mode. Once it is in USB Boot mode it appears as a USB device to the
computer.
- Is the computer detecting the USB device? At a terminal window type "dmesg"
to see the messages. Look for /dev/ttyUSB0 or /dev/ttyUSB1 or /dev/ttyUSBx
where x= 1..10
- Have you removed "brltty" per the Wiki? "sudo apt-get remove brltty" this is
known to interfere with USB and Paparazzi.
