==Introduction==
In order to run correctly, UCM-iMX8M-Mini Linux requires compatible u-boot version:
{|class="wikitable"
!U-boot version
!Linux build version
|-
|1.3
|1.x
|-
|2.0
|2.x
|}

==Check U-Boot version==
* The U-Boot version string is displayed during boot. Also this string can be retrieved with the '''version''' command.
Example:

U-Boot 2020.04-ucm-imx8m-mini-2.0-5.4.24-2.1.0+g4979a99482 (Sep 08 2020 - 14:39:42 +0000)

Where: machine name is highlighted in blue; version number in yellow.

==Updating U-Boot==
Use an appropriate Linux image.
Write the image to a micro-SD card and boot from it [[UCM-iMX8M-Mini:_Yocto_Linux:_Manual_Installation:_SD_card| following the instruction]]. Issue the following command:
<pre>cl-uboot</pre>
Choose the block device to be flashed in the menu.

Note that with previous versions u-boot was stored in '''''User''''' partition of eMMC devices; to overwrite it, choose the destination boot device '''mmcblk2'''.
Once the boot loader is updated successfully, the OS image can be updated [[UCM-iMX8M-Mini:_Yocto_Linux:_Installing_Yocto_images_onto_UCM-iMX8M-Mini_eMMC#Installing Yocto images onto UCM-iMX8M-Mini eMMC|as described here]].
