Hi,
I am working on a Toradex Apalis iMX8 device. I have built a reference operating system using Yocto by following the guide at Build a Reference Image with Yocto Project/OpenEmbedded. I built the tdx-reference-multimedia-image and copied the Apalis-iMX8_Reference-Multimedia-Image-Tezi_6.7.0-devel-20240522141537+build.0.tar file to an SD card and inserted it into the Toradex board. I was able to see the SD card yesterday. But today, when I turn on the board, the red light turns on even before putting it into recovery mode. Additionally, my host device is unable to detect the Toradex board via USB.Please help me to solve the issue.

Hello,
When facing issues with the host system not detecting the Toradex Apalis iMX8 board via USB, especially in the context of entering recovery mode or during initial setup phases, it’s essential to systematically troubleshoot both the hardware setup and the software environment. Here are several steps and checks to consider:
-
Power Cycle the Board: Completely power off the board, disconnect all power sources, and then reconnect. This ensures the board starts from a known state.
-
Check USB Connection: Ensure the USB cable is properly connected to the correct USB port on the carrier board and the host computer. For the Apalis iMX8, you should be using a USB Micro-B to Type-A cable connected to the X9 (OTG) port when using an Ixora carrier board, for example. Verify the cable is functioning correctly by testing with another device if possible.
-
Carrier Board Setup: Double-check that the carrier board is set up correctly for recovery mode. This includes ensuring any necessary jumpers or switches are correctly configured. For the Ixora carrier board, for example, ensure that the JP2 jumper is removed to enable OTG client mode.
-
Enter Recovery Mode: Follow the specific steps for your carrier board to enter recovery mode. This often involves holding down a specific button or shorting specific pins while powering on the board. For the Apalis iMX8 on an Ixora carrier board, you would short the recovery pads and then power on the board.
-
Host Machine Setup: On your host machine, ensure you have the necessary drivers or software to detect the board. For Linux, this might simply involve checking dmesg or lsusb output. A new device should appear when the board enters recovery mode.
-
Try a Different Host Port or Computer: Sometimes, the issue might be with the host computer’s USB port. Try connecting to a different port or a different computer if available.
-
Inspect for Hardware Issues: Check both the carrier board and the SoM for any visible signs of damage or issues. Ensure the SoM is properly seated in the carrier board.
-
Consult the Carrier Board and SoM Manuals: Ensure all steps align with the official documentation for entering recovery mode for your specific carrier board and SoM configuration.
If after these steps, the host system still does not detect the Toradex board, it might indicate a more serious hardware issue with either the carrier board, the SoM, or the

Hi @SruthiSathyan,
Please consider the debug points suggested by Toradex AI.
In addition to these, check what debug messages you are getting on UART.
Also, re-check if the module is properly inserted into the carrier board.
Let me know if you need further help

Hi @SruthiSathyan ,
Is the red LED keeps on glowing continuously or glows initially and then stops?
Please connect UART (X29) and check what messages you are getting?
Yes the red light keeps glowing continously.
