== Updating Device Firmware

+ programmed directly over their USB connectors (self

+ ifdef::telemega[]
+ TeleMetrum v1, TeleMini and TeleDongle v0.2 are
all programmed by using another device as a programmer (pair
programming). It's important to recognize which kind of devices
you have before trying to reprogram them.

You may wish to begin by ensuring you have current firmware
images. These are distributed as part of the AltOS software
download the most recent version from
http://www.altusmetrum.org/AltOS/
- If you need to update the firmware on a TeleDongle v0.2, we
- recommend updating the altimeter first, before updating
- TeleDongle. However, note that TeleDongle rarely need to be
- updated. Any firmware version 1.0.1 or later will work,
- version 1.2.1 may have improved receiver performance slightly.
-
- Self-programmable devices (TeleMega, TeleMetrum v2, EasyMega
- and EasyMini) are reprogrammed by connecting them to your
- computer over USB

+ connecting them to your computer over USB.
. Attach a battery if necessary and power switch to
the target device. Power up the device.
. Select the image you want to flash to the device,
which should have a name in the form
<product>-v<product-version>-<software-version>.ihx,
- such as TeleMega-v1.0-1.3.0.ihx.
+ such as EasyMini-v1.0-1.6.0.ihx.
. Make sure the configuration parameters are
reasonable looking. If the serial number and/or RF
connectors will force the boot loader to start, even if the
regular operating system has been corrupted in some way.

TeleMega::
Connect pin 6 and pin 1 of the companion
battery. Pin 7 carries 3.3V and the board will crash
if that is connected to pin 1, but shouldn't damage
the board.
+ endif::telemega[]
+ ifdef::easymega[]
EasyMega::
Connect pin 6 and pin 1 of the companion
battery. Pin 7 carries 3.3V and the board will crash
if that is connected to pin 1, but shouldn't damage
the board.
+ endif::easymega[]
+ ifdef::telemetrum[]
TeleMetrum v2::
Connect pin 6 and pin 1 of the companion
battery. Pin 7 carries 3.3V and the board will crash
if that is connected to pin 1, but shouldn't damage
the board.
+ endif::telemetrum[]
+ ifdef::easymini[]
EasyMini::
Connect pin 6 and pin 1 of the debug connector, which
identified by the square pad around it, and then the
pins could sequentially across the board, making Pin 6
the one on the other end of the row.
+ endif::easymini[]
+ ifdef::telemetrum[]
TeleDongle v3::
Connect pin 32 on the CPU to ground. Pin 32 is closest
to the USB wires on the row of pins towards the center
of the board. Ground is available on the capacitor
next to it, on the end towards the USB wires.
+ endif::telemetrum[]
Once you've located the right pins:
the board has been powered up, you can remove the
piece of wire.

=== Pair Programming
The big concept to understand is that you have to use
support programming directly over USB for these
devices.
+ If you need to update the firmware on a TeleDongle
+ v0.2, we recommend updating the altimeter first,
+ before updating TeleDongle. However, note that
+ TeleDongle rarely need to be updated. Any firmware
+ version 1.0.1 or later will work, version 1.2.1 may
+ have improved receiver performance slightly.

==== Updating TeleMetrum v1.x Firmware
. Find the 'programming cable' that you got as
TeleMetrum to help ensure that the cabling to
companion boards used in a rocket don't ever come
loose accidentally in flight.
