Getting started

The IOT-GATE-IMX8PLUS gateway expects the bootloader to be located on hardware BOOT partition 1. When flashing firmware, ensure that both the bootloader and a complete disk image, generated using the fwup CLI tool, are provided.

Prerequisites

• NXP mfgtools
• fwup

Building a firmware image

fwup -a \
  -d $FW_PROJECT_DIR/_build/$TARGET/nerves/images/firmware.img \
  -i $FW_PROJECT_DIR/_build/$TARGET/nerves/images/firmware.fw  \
  -t complete

Flashing the firmware image

uuu \
  -b emmc_all \
  $BINARIES_DIR/imx8-boot-sd.bin \
  $FW_PROJECT_DIR/_build/$TARGET/nerves/images/firmware.img

Flashing only U-Boot

uuu -b emmc $BINARIES_DIR/imx8-boot-sd.bin
