Hello Aishwarya,

Thank you for reaching out with your questions about the Toradex Verdin iMX8MP board. Let me address each of your queries:

1. Using SD Card as Default Boot Media:

   While it is possible to boot from an SD card, this method is generally used for development and testing rather than as a default boot media in production. To boot from an SD card, you need to prepare it with the necessary boot and root filesystem partitions. You can create a bootable image using the OpenEmbedded build system and write it to the SD card with tools like dd. Once prepared, insert the SD card into the board, interrupt the U-Boot process by pressing any key during boot, and execute run bootcmd_mmc1 to boot from the SD card.

2. Flashing Images Using UUU on eMMC:

   The Universal Update Utility (UUU) is indeed suitable for flashing images to the eMMC. Ensure you have UUU installed on your host machine. Typically, you need to set the board into recovery mode and use UUU commands to transfer the image to the eMMC. The exact steps can vary, so it’s best to refer to the UUU documentation specific to your board for detailed instructions.

3. Recommended Way to Update Images in Production:

   For production environments, Toradex recommends using the Toradex Easy Installer. This tool is robust and allows for flashing images via Ethernet, USB, or SD card. It supports automated installations and can be customized to meet your specific needs, making it ideal for mass production scenarios.

I hope this information helps you with your project. If you have any more questions, feel free to ask.

Best regards,

Flashing my own uboot and wic (w/ rootfs etc.) image to eMMC on Verdin IMX8MPlus with UUU

I’ve been poking around Toradex’s Artifactory and documetation to find an example uuu file that actually flashes the bootloader to the boot partition and a disk image (ie .wic, that is, including partition table and several partitions) to the eMMC on a Verdin IMX8MPlus. All I could find so far are examples of how to load u-boot/imxboot, kernel, etc into RAM and run it that are in some of the builds in the recovery/ subdir. But I already have that working, now looking at how to flash my own. …

Updating a Device through USB

I have been looking around your website for information and examples regarding updating a device once it has come out of production and has an installed customized TorizonCore Image installed and running with some preprovisioned contaiers. For some reason i can’t seem to find the right example of how to update the image and/or application(s) through a USB without having to either do it online or reinstalling a clean Install. I have found information about the secure offline update, but we dont…
