I am unable to load TEZI on my Apalis iMX8QM 4GB IT V1.1D module on the Ixora carrier. When I received the board I successfully booted into TEZI and loaded the image with Acontis etherCAT support. However, because I was having some trouble establishing a debug connection to this, I decided to revert to one of the other images that had a UI. I put the board into recovery mode with the OTG USB port connected and ran the recovery script. This is the output:

Hello! Thank you for sharing these details about your issue with loading Toradex Easy Installer (TEZI) on your Apalis iMX8 module using the Ixora carrier board.
Based on your description and the provided logs, here are some things to check and try:
1. USB Host and Port Issues
The Apalis iMX8 can sometimes have issues with certain USB host controllers or ports—this is a known issue. Please try the following:
Change to another USB port on your computer or use a different computer, if available.
Ensure you are using the USB OTG port on the Ixora carrier board (X9 micro-USB).
A different host or USB port often resolves hanging issues during recovery mode. Apalis iMX8 Hardware Docs
2. Recovery Mode Timing
It’s important to hold the recovery button:
Hold the RECOVERY button for 6–10 seconds after powering on the carrier board and before running the recovery script.
Confirm you’re pressing the correct button on the Ixora carrier board.
If none of these steps resolve the issue, let me know—there are alternative recovery approaches, such as using a different operating system for recovery or running the process in a virtual machine.
@ToradexAI Just confirming that I have tried waiting for a few minutes and have also power cycled. I’m fairly sure that I’m correctly in recovery mode because the OTG interface doesn’t enumerate on the image I have installed, so I must have entered a recovery mode (or at least a different mode) in order for that behaviour to change.
I’ve also edited the original post with the exact module version ( Apalis iMX8QM 4GB IT V1.1D)
I’m separately having problems with the serial connection, so I can’t tell what is being produced on the debug port.
Through a fluke set of actions, I seem to have just managed to make reprogramming work. This is what I had to do:
Start with power disconnected and recovery jumper shorted
Connect a USB C to USB A cable from my laptop to lower port of X8
Power on button
Wait 6 seconds
Remove recovery short
Start recovery script
Remove USB A cable from X8
Connect usb micro OTG
Loading now completes successfully
I initially assumed the connection to the lower port of X8 was a red herring, but if I repeat the sequence without this step it doesn’t work. Also if I follow the precise instructions on Loading Toradex Easy Installer | Toradex Developer Center then it doesn’t work either. I’d love to understand which are the important parts of this sequence so that I can reliably reprogramme the device in the future! Thanks.
You were right, I tried using the recovery jumper on the Ixora and it didn’t load.
Could you please try the method described using the Evaluation board? There are two pads on the Apalis module that you can short-circuit to enter the recovery mode.
Please don’t hesitate to ask if you have any questions or issues.
Thanks for the follow up. I’ll give that a go to help get the bottom of the issue, but in general it’s not an ideal solution as those pads are hidden under a heatsink which I will need to remove.
Yes, I know. I only want to be sure that this is a general issue, not something particular to my setup. Once we define this, I can talk to the responsible teams about this issue and they will try to solve it.
Hi @lucas_az.tx, I have tried using the instructions for the dev board as you suggest, and I can confirm that it works first time without any problems.
Is it possible to test with another module/carrier board? I’ve tried with another Apalis and Ixora, and it worked as expected. I short-circuited the pads on Ixora, ran the script, and it installed the TEZI.
