Need to flash image through JTAG

Technical Support

Hi team,

We are doing a Yocto project for IMX8QM. We tried flashing through SD card and eMMC, but it didn’t work for us.
Could you please provide a solution for flashing an image using JTAG?

Flashing an image using JTAG is not a common method for deploying images on Toradex modules, and typically, JTAG is used for debugging purposes rather than for flashing images. However, if you need to use JTAG for flashing, you would generally need a JTAG debugger and appropriate software tools that support your SoM (System on Module).

Here are some general steps you might follow:

  1. Set Up JTAG Hardware: Connect your JTAG debugger to the JTAG interface on the i.MX8QM module.

  2. Install JTAG Software: Use software tools that support JTAG flashing for i.MX8QM. Some common tools include OpenOCD or vendor-specific tools like Lauterbach.

  3. Prepare the Image: Ensure that the image you want to flash is in a format that can be written directly to the flash memory via JTAG.

  4. Flash the Image:

    • Use the JTAG software to connect to the target device.
    • Load the image into the appropriate memory location. This typically involves specifying the memory address and the image file.
    • Execute the flash command to write the image to the flash memory.

  5. Verify the Flashing: After flashing, verify that the image has been written correctly by reading back the memory and comparing it with the original image file.

Since this is a specialized task, you might need to refer to the specific documentation for your JTAG debugger and the i.MX8QM processor. Additionally, you may want to consult with NXP’s support or community forums for more detailed guidance on using JTAG for flashing images on i.MX8QM.

If you continue to face issues with SD card and eMMC flashing, it might be helpful to troubleshoot those methods further, as they are the standard and supported methods for flashing images on Toradex modules.

Hi @karthikgowda6,
By taking reference from your other post, your flashing through SD card issue seems to be solved.
