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.
Built 13+ Tiny 13 v1.1 autopilot boards in-house.  Distributed boards into the group to break-even.


'''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 error accessing USB when trying to load code to the Autopilot

* LiPower Lites 3S1P 2100mAh 18C LiPo Batteries x 2
* APC 9x6E Propeller (checked to draw ~ 11.5A)


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

'''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.
* Hot Air Reflow Rework Station
* SMT Soldering Station
* Molex PicoBlade Crimpers
* Molex Micro-Fit 3.0 Crimpers
* 10-20 of each of every PicoBlade and MicroFit connectors
* Various Alpha 26 AWG Teflon Hook-up Wire

'''Q:''' How do I load the USB Bootloader onto the Tiny?


'''A:''' Start by wiring up 3.3V RS232 from the PC to the Tiny. 
[[Category:Members]]
 
The serial lines on the ARM7 micro are 5V tolerant so if it helps cut down on complexity/parts you could use 5V RS232 for this.  ''Optional: You could also form a basic resistor voltage divider on the PC TX -> AP RX''
 
*PC SERIAL_TX -> LPC_RXD_0 (SERIAL_1-7)
*PC SERIAL_RX -> LPC_TXD_0 (SERIAL_1-8)
*PC SERIAL_GND -> GND (SERIAL_1-1)
*LPC_P0.14 (SERIAL_1-5) must be asserted low (held to ground) while the Tiny powers up in order to enter the Serial Boot Loader.  (You could also wire this to a pushbutton which ties it to ground, holding this button briefly while you power up the AP.  This pin does not need to stay low during the programming or any time afterwards)
 
once these connections have been made, execute this command in a console
