Currently building building Tiny 1.1 hardware. Has hot air reflow, solder paste, smt, linux capabilities and keeps stock of some parts on hand. Let me know if anyone needs any assistance.

Q: [Tiny 1.1] My AP begins executing only after downloading code to it and not after a reset.

A: Make sure when you compiled your initial USB Bootloader you selected the right USB enable pin. If using P0.23 add PROC=GENERIC to the make process.

Q: [Tiny 1.1] I get this error accessing USB when trying to load code to the Autopilot:

Found USB device
USB error: Operation not permitted 
unlock failed

A: You need to copy a USB rules file following the instructions below

# cd [paparazzi3 folder]
# cp conf/system/udev/rules/10-paparazzi.rules /etc/udev/rules.d/

Q: [Tiny 0.9-1.1] What is the command to compile the ARM7 code?

A: the two relevent commands are below. Replace [AIRCRAFT] with the name of your aircraft.

# cd [parazzi3 folder]'
# make AIRCRAFT=[AIRCRAFT] ap.compile

to download code that has already been compiled

# cd [parazzi3 folder]'
# make AIRCRAFT=[AIRCRAFT] ap.upload

Q: How do I get GCS to talk to the AP with straight serial and not a modem?

A: Here is an example of a section of my paparazzi3/conf/control_panel.xml
