I've recently made a DIY adapter but I'm unable to load the firmware in the GIMX loader. My PC recognizes my Teensy 2.0 board and the UART in the devices menu. I've done the fast and slow blink test with the Teensy but when it comes to doing the firmware on GIMX I get the "failed to load packet header" error. I have a data cable which got me further than the charging only cable so that seems like it's fine.
I have also tried swapping RX and TX wires. I'll try to upload pictures shortly of the device.
Here are the parts I used

I cut the headers off one end and soldered the wires directly

*SOLVED* - needed to load the atmega32u4.hex file to the Teensy. Link would not work for me through the tutorial.

Re: Unable to load firmware/failed packet header
Here is my soldering job. One of the wires in currently soldered from the back of the board.

You need to update firmware with Teensy loader.

Re: Unable to load firmware/failed packet header
As far as I know I did that with the slow and fast blink hex files. Is there an atmega32u4 hex file? I saw that referenced in another page but I'm not sure where to find it. If I remember correctly I did try to download firmware files from the tutorial but the link didn't take me to another page than where I already was.

Re: Unable to load firmware/failed packet header
This is the one you need
https://github.com/matlo/GIMX-firmwares ... es-8.0.zip
If this does not work i think you have to switch the TXD and RXD on the Uart.

Re: Unable to load firmware/failed packet header
Yep that was it. In the tutorial the link to the firmwares didn't open a new page. Almost like it was being blocked like an ad. Everything works as of now. Thanks.
