Introduction
U-boot version 3.2 or above is required for running the latest Debian and Yocto images.
Checking current U-Boot version
- U-Boot version is displayed during the boot sequence:
U-Boot 2021.04-iot-gate-imx8-3.2
- U-Boot version can be retrieved with the "version" command:
IOT-GATE-iMX8 => version
U-Boot 2021.04-iot-gate-imx8-3.2
Updating U-Boot
- Download the latest U-Boot binary image from the u-boot section of the IOT-GATE-iMX8 resources.
- Extract the image archive file.
- Deploy the image (iot-gate-imx8_uboot-update.img) to a USB flash drive.
dd if=iot-gate-imx8_uboot-update.img of=/dev/sdX
- Plug the USB flash drive into the front panel USB port (located near the power button).
- Restart the IOT-GATE-iMX8.
- Wait for SUCCESS message
- Extract the USB flash drive and restart the device
|
U-Boot update failure can lead to a state of the un-bootable device. In that case U-Boot recovery is needed. |
