Truly dead after firmware upgrade Ė any ideas?
« on: Thu, 17 April 2014, 15:50:43 »
Hi folks!

I tried to upgrade my TEKís firmware today and somehow managed to completly brick it. I used the official upgrade tool and a 3.40 hex file from the layout designer (on an old Windows XP machine). First time I pressed Upgrade it went from 0% to 100% but didnít display a success message, so I pressed it a second time and got a DFU Reset failed error. After reconnecting the TEK it doesnít even do any USB enumeration anymore. dmesg on a Linux machine is completly quiet.
Soooo, I guess there is no way to flash the firmware over USB if I donít even see a device ID etc.? How accommodating is Truly Ergonomic concerning replacements in such cases? Would it be possible to do some open heart surgery and flash the firmware with a hardware programmer and some wires?

Regards
Michael

I've heard their customer service is not so good.  Did you turn off the DIP switch before flashing?

You can try resetting the MCU/firmware, it might allow you to reinstall a firmware. It works most of the time, if you really bricked the MCU, then there is not much to do.

Open the keyboard
Reset the MCU
Upload a Firmware
Close the keyboard

------------------------------------------------------------------

How to open the Truly Ergonomic Keyboard:
http://geekhack.org/index.php?topic=38943.msg803906#msg803906

Info provided by Truly Ergonomic:

Please be aware that if you open the keyboard, you will dismiss all guarantees.

1.   First remove the 9 screws that hold the palmrest, and then remove the palmrest.

2.   Then remove the top 2 screws and the 4 additional screws that were hidden by the palmrest.

3.   There are 2 additional screws under the back label Ė located on each of the top corners. Press the label on each corner with your thumbs or fingers to feel where the screw cavity is located, and then use a screwdriver or cutter to split through the label. http://www.trulyergonomic.com/store/image/data/Truly_Ergonomic-underside_all_screws.jpg

4.   After all screws are out, you need to 'horizontally-twist' the top-body against the bottom-body as there are 6 'hooks' that hold these two parts together; 4 hooks on the backside where the cable is located, and 1 hook on each side.

------------------------------------------------------------------

How to Reset the MCU
http://geekhack.org/index.php?topic=38943.msg787293#msg787293

With the keyboard plugged into your computer:
Touch Pin 1 and pin 36 - the upper pins of each side of the chip when the round angle mark is at the top left.

Upload default firmware:

Hope it helps.

Thanks for the advice. Unfortunately the reset didnít help. Looks like the Controller was really running without any (or broken) firmware. Itís really a shame if an end-user device from 2011 can be broken by something as simple as a failed firmware update.

Anyways, I got impatient waiting for an answer from Truly Ergonomic, so I re-wired the whole keyboard (88 diodes, 3m of wire  :thumb:) and used an Arduino Micro as controller. Works like a charm and canít be broken by a firmware upgrade ;D

Great that you were able to rewire. Can you post some images.

Is the Arduino controller programmable, or you don't need reprogramming?

That's impressive.  Glad you got it working.

Using the reset pin jumps to the bootloader.  It shouldn't be possible to corrupt the bootloader with a botched firmware load.

DIP switch #5 must be ON (firmware protected) during the reset to have the MCU restarting in ISP mode (Yes, that's the opposite position of the DIP switch #5 OFF that allows firmware to be reprogrammed the "normal" way !)

Hello Mike,

Would you PLEASE be so kind to share some details on your re-wiring of the TEK?
Did you load QMK on it?

Thanks a lot,

Pierre

Was QMK a thing in 2014?

Sounds like he essentially did a whole hand-wire job on it.  He probably used TMK given the year, as spamray noted.
