This article describes flashing U-Boot firmware image with a Linux Host using Universal Update Utility (hereinafter '''UUU''').

{{Note|Follow the [https://github.com/NXPmicro/mfgtools/blob/master/README.md Universal Update Utility instructions] to install and setup the UUU tool on a host Linux station.}}

= Getting Recovery U-Boot Firmware Image =
* Download the '''IOT-LINK firmware recovery image''' from the [https://www.compulab.com/products/iot-gateways/iot-link-industrial-iot-gateway/#devres U-boot section of IOT-LINK Resources] to the host Linux station.
* Extract the archive onto the host Linux station:
unzip iot-link_firmware-recovery-image.zip -d /path/to/iot-link-firmware

= Flashing U-Boot Firmware =
* IOT-LINK USB SDP port is located behind the back panel. Remove the back panel to access the USB SDP connector.
* Connect the SDP port with the host Linux station USB port using a standard micro-USB cable.
* Power off the device via the main DC input.
