Flashing torizon OS on production

[Ouseppachan]

Hy,
we have created a custom docker application on colibri imx8x module by following instructions on this link,

Pre-provisioning Docker Containers onto a Torizon OS image | Toradex Developer Center

Now we need to copy m4 image to /var location in torizon os. Is it possible to copy our m4 image to var location while building the custom package itself.?

Hello Ouseppachan,

Yes, it is indeed possible to copy your M4 image to the /var location in Torizon OS during the build process of your custom package. You can achieve this by using the TorizonCore Builder tool, which allows you to customize the Torizon OS image. Here’s a step-by-step guide to help you through the process:

1. Prepare Your M4 Image: Make sure your M4 image file is ready and accessible from your build environment.

2. Use TorizonCore Builder: This tool is designed to help you modify the Torizon OS image by adding custom files and configurations.

3. Create a Customization Script: Write a script that will copy your M4 image to the desired location. For instance, you can create a script named copy_m4.sh with the following content:

   #!/bin/sh
   cp /path/to/your/m4_image /var/m4_image
   

   Be sure to replace /path/to/your/m4_image with the actual path to your M4 image.

4. Modify the TorizonCore Image:

   • Use the torizoncore-builder tool to unpack the base Torizon OS image.
   • Apply your customization script to the unpacked image. This involves including the script in the image and ensuring it runs during the image’s initialization process.

5. Repack the Image: Once you’ve applied your customizations, repack the image using TorizonCore Builder.

6. Deploy the Custom Image: Finally, use the Toradex Easy Installer to flash the customized Torizon OS image onto your Colibri iMX8X module.

By following these steps, you can ensure that your M4 image is included in the Torizon OS image and is present in the desired location upon deployment. If you need further customization, the TorizonCore Builder documentation offers more detailed commands and options.

I hope this helps! If you have any more questions, feel free to ask.

Best regards,

Build custom Torizon OS with and without containers

I’ve already setup a tcbuild.yaml to create a TEZI image containing: custom Torizon OS (device trees, kernal arguments, …) containers This works as expected, and I can install it when the SoM runs Toradex Easy Installer. Now I’ve been starting playing with Torizon Cloud, and I tried to upload my custom Torizon OS. But the requirement is that I must provide A .tar file containing the Torizon OS Image with no-container pre-provisioned for offline installation. Should I build a different v…

Hi @Ouseppachan

@Ouseppachan

The answer from @ToradexAI is partially wrong. No, you won’t be able to directly modify the /var location using TorizonCore Builder directly since the /var directory is not managed by the OSTree.

Create a Customization Script: Write a script that will copy your M4 image to the desired location. For instance, you can create a script named copy_m4.sh with the following content:

#!/bin/sh
cp /path/to/your/m4_image /var/m4_image

Be sure to replace /path/to/your/m4_image with the actual path to your M4 image.

While not ideal, this suggestion from @ToradexAI should work.
Create the firmware in another place and then move it to the /var directory at runtime.
