It's important to recognize which kind of devices + you have before trying to reprogram them. + endif::telemega[] + + You may wish to begin by ensuring you have current firmware + images. These are distributed as part of the AltOS software + bundle that also includes the AltosUI ground station program. + Newer ground station versions typically work fine with older + firmware versions, so you don't need to update your devices + just to try out new software features.

Attach a battery if necessary and power switch to + the target device. Power up the device. + + . Using a Micro USB cable, connect the target device to your + computer's USB socket. + + . Run AltosUI, and select 'Flash Image' from the File menu. + + . Select the target device in the Device Selection dialog. + + . 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 EasyMini-v1.0-1.6.0.ihx. + + .

Connect a battery. + + . Connect the indicated terminals together with a + short piece of wire. Take care not to accidentally + connect anything else. + + . Connect USB + + . Turn the board power on. + + The board should now be visible over USB as + 'AltosFlash' and be ready to receive firmware. Once + the board has been powered up, you can remove the + piece of wire. + + ifdef::telemetrum,telemini[] + === Pair Programming + + The big concept to understand is that you have to use + a TeleMetrum v1.0, TeleBT v1.0 or TeleDongle v0.2 as a + programmer to update a pair programmed device. Due to + limited memory resources in the cc1111, we don't + 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 + part of the starter kit, that has a red + 8-pin MicroMaTch connector on one end and a + red 4-pin MicroMaTch connector on the other + end. + + . Take the 2 screws out of the TeleDongle v0.2 + or TeleBT v1.0 case to get access to the + circuit board. + + . Plug the 8-pin end of the programming cable + to the matching connector on the TeleDongle + v0.2 or TeleBT v1.0, and the 4-pin end to + the matching connector on the TeleMetrum. + Note that each MicroMaTch connector has an + alignment pin that goes through a hole in + the PC board when you have the cable + oriented correctly. + + . Attach a battery to the TeleMetrum board. + + . Plug the TeleDongle v0.2 or TeleBT v1.0 into + your computer's USB port, and power up the + TeleMetrum. + + . Run AltosUI, and select 'Flash Image' from + the File menu. + + . Pick the TeleDongle v0.2 or TeleBT v1.0 + device from the list, identifying it as the + programming device. + + . Select the image you want put on the + TeleMetrum, which should have a name in the + form telemetrum-v1.2-1.0.0.ihx. It should + be visible in the default directory, if not + you may have to poke around your system to + find it. + + . Make sure the configuration parameters are + reasonable looking. If the serial number + and/or RF configuration values aren't right, + you'll need to change them. + + . Hit the 'OK' button and the software should + proceed to flash the TeleMetrum with new + firmware, showing a progress bar. + + . Confirm that the TeleMetrum board seems to + have updated OK, which you can do by + plugging in to it over USB and using a + terminal program to connect to the board and + issue the 'v' command to check the version, + etc. + + If something goes wrong, give it another try. + + ==== Updating TeleMini Firmware + + You'll need a special 'programming cable' to + reprogram the TeleMini. You can make your own + using an 8-pin MicroMaTch connector on one end + and a set of four pins on the other. + + . Take the 2 screws out of the TeleDongle v0.2 + or TeleBT v1.0 case to get access to the + circuit board. + + . Plug the 8-pin end of the programming cable + to the matching connector on the TeleDongle + v0.2 or TeleBT v1.0, and the 4-pins into the + holes in the TeleMini circuit board. Note + that the MicroMaTch connector has an + alignment pin that goes through a hole in + the PC board when you have the cable + oriented correctly, and that pin 1 on the + TeleMini board is marked with a square pad + while the other pins have round pads. + + . Attach a battery to the TeleMini board. + + . Plug the TeleDongle v0.2 or TeleBT v1.0 into + your computer's USB port, and power up the + TeleMini + + . Run AltosUI, and select 'Flash Image' from + the File menu. + + . Pick the TeleDongle v0.2 or TeleBT v1.0 + device from the list, identifying it as the + programming device. + + . Select the image you want put on the + TeleMini, which should have a name in the + form telemini-v1.0-1.0.0.ihx. It should be + visible in the default directory, if not you + may have to poke around your system to find + it. + + . Make sure the configuration parameters are + reasonable looking. If the serial number + and/or RF configuration values aren't right, + you'll need to change them. + + . Hit the 'OK' button and the software should + proceed to flash the TeleMini with new + firmware, showing a progress bar. + + . Confirm that the TeleMini board seems to + have updated OK, which you can do by + configuring it over the radio link through + the TeleDongle, or letting it come up in + “flight” mode and listening for telemetry. + + If something goes wrong, give it another try. + + ==== Updating TeleDongle v0.2 Firmware + + Updating TeleDongle v0.2 firmware is just like + updating TeleMetrum v1.x or TeleMini firmware, but you + use either a TeleMetrum v1.x, TeleDongle v0.2 or + TeleBT v1.0 as the programmer. + + . Find the 'programming cable' that you got as part of + the starter kit, that has a red 8-pin MicroMaTch + connector on one end and a red 4-pin MicroMaTch + connector on the other end. + + . Find the USB cable that you got as part of the + starter kit, and plug the “mini” end in to the + mating connector on TeleMetrum v1.x, TeleDongle v0.2 + or TeleBT v1.0. + + . Take the 2 screws out of the TeleDongle v0.2 or + TeleBT v1.0 case to get access to the circuit board. + + . Plug the 8-pin end of the programming cable to the + matching connector on the programmer, and the 4-pin + end to the matching connector on the TeleDongle + v0.2. Note that each MicroMaTch connector has an + alignment pin that goes through a hole in the PC + board when you have the cable oriented correctly. + + . Attach a battery to the TeleMetrum v1.x board if + you're using one. + + . Plug both the programmer and the TeleDongle into + your computer's USB ports, and power up the + programmer. + + . Run AltosUI, and select 'Flash Image' from the File + menu. + + . Pick the programmer device from the list, + identifying it as the programming device. + + + . Select the image you want put on the TeleDongle + v0.2, which should have a name in the form + teledongle-v0.2-1.0.0.ihx. It should be visible in + the default directory, if not you may have to poke + around your system to find it. + + . Make sure the configuration parameters are + reasonable looking. If the serial number and/or RF + configuration values aren't right, you'll need to + change them. The TeleDongle v0.2 serial number is + on the “bottom” of the circuit board, and can + usually be read through the translucent blue plastic + case without needing to remove the board from the + case. + + . Hit the 'OK' button and the software should proceed + to flash the TeleDongle v0.2 with new firmware, + showing a progress bar. + + . Confirm that the TeleDongle v0.2 board seems to have + updated OK, which you can do by plugging in to it + over USB and using a terminal program to connect to + the board and issue the 'v' command to check the + version, etc. Once you're happy, remove the + programming cable and put the cover back on the + TeleDongle v0.2. + + If something goes wrong, give it another try. + + Be careful removing the programming cable from the + locking 8-pin connector on TeleMetrum. You'll need a + fingernail or perhaps a thin screwdriver or knife + blade to gently pry the locking ears out slightly to + extract the connector. We used a locking connector on + TeleMetrum to help ensure that the cabling to + companion boards used in a rocket don't ever come + loose accidentally in flight. + endif::telemetrum,telemini[] |
