ADLINK MXA-200 IoT Gateway

This is the base Nerves System configuration for the ADLINK MXA-200.

Feature	Description
CPU	1.8 GHz quad-core Cortex-A53 (64-bit)
Storage	eMMC
Linux kernel	5.15
IEx terminal	UART ttymxc1
GPIO, I2C, SPI	Yes - Elixir Circuits
Ethernet	Yes
WiFi	Yes
Bluetooth	Yes
RTC	Yes
HW Watchdog	Yes

Getting started

Flashing firmware for the first time will be done via NXP's Universal Update Utility using the Micro-B USB port. A Nerves firmware project using this system as a target is required. For more information see Nerves' Getting Started guide.

Debug Console is available through the internal 3 pin 2.5mm header labeled as CN2102.

Pin	Signal
0	TX
1	RX
2	GND

By default the device is configured to boot off eMMC, this can be changed via the Boot Settings DIP switch labeled as SW701. This switch is also used to place the device in Recovery mode for flashing using uuu cli.

1	2	3	4	Boot Settings
0	1	1	0	SD Card
0	1	0	0	eMMC
0	0	0	1	Recovery

Prerequisites

• NXP mfgtools
• fwup

Building a firmware image

In your Nerves Firmware Project directory, run:

mix firmware

Generate an image file using fwup.

fwup -a \
  -d /tmp/firmware.img \
  -i _build/${MIX_TARGET}_${MIX_ENV}/nerves/images/${YOUR_PROJECT_NAME}.fw \
  -t complete

Flashing the firmware image

Note: uuu requires the bootloader to be provided even if it might be embedded in the full firmware image.

Extract the bootloader from your .fw firmware file.

unzip -d /tmp/ \
  _build/${MIX_TARGET}_${MIX_ENV}/nerves/images/${YOUR_PROJECT_NAME}.fw

Set the Boot Settings DIP switch to Recovery mode and ensure your devices is listed when running uuu -lsusb.

uuu \
  -b emmc_all \
  /tmp/data/imx8-boot-sd.bin \
  /tmp/firmware.img

Power off the device and toggle Boot Settings DIP switch back to eMMC mode.

Flashing only U-Boot

Extract the bootloader from your .fw firmware file.

unzip -d /tmp/ \
  _build/${MIX_TARGET}_${MIX_ENV}/nerves/images/${YOUR_PROJECT_NAME}.fw

uuu -b emmc /tmp/data/imx8-boot-sd.bin
