Introduction

In the last years, Debian-based distributions⁠—which are very widespread in desktop/server environments—have grown in popularity in the embedded world as well. Nowadays, there are several approaches to create such a distribution for embedded targets, however. ELBE, meta-eid, and armbian are just three examples of different tools available today [1].

This Technical Note shows how to run such a distribution on SBCSPG, a product designed and manufactured by DAVE Embedded Systems to build compact IoT gateways for industrial applications. Specifically, this example makes use of Armbian Stretch, which is based on Debian 9.

[1] For more details, please see for instance these presentations:

• Debian & Yocto: State of the Art (Oct 23rd, 2018)
• Debian + YoctoProject Based Projects: Collaboration Status (Dec 1st, 2017)

The hardware platform

As stated previously, the SBCSPG gateway is suited to implement low-cost edge computing devices.

Cloud and Edge computing in a typical IIoT scenario (image source: [1])

From an architectural standpoint, SBCSPG is similar to the SBC Lynx. As such, it is powered by NXP i.MX6UL system-on-chip (SoC).

SBCSPG Industrial IoT gateway

It is equipped with three network interfaces⁠—two Ethernet ports and a WiFi⁠—and provides several combinations of serial ports like RS232, RS485, and RS422. It also has two USB ports (host and OTG) and a microSD slot.

Creating the root file system

To create the root file system, the procedure described here was followed. Before starting the actual build process, the following patch was applied in order to add the support for the SBCSPG target.

When the process is completed, the output/images directory is populated with the following files:

Armbian_5.91_Sbcspg_Debian_stretch_default_.img
Armbian_5.91_Sbcspg_Debian_stretch_default_.txt

The .img is the one we need to deploy the root file system onto the target platform.

Even though it is not recommended, the build process was run natively on a PC equipped with Ubuntu 18.04.

Deploying the root file system onto the target

This procedure consists of the following steps:

• Mount the .img file
• Copy the root file system to a microSD card
• Move the microSD card to the target
• Configure the target in order to mount the armbian root file system from the microSD card.

It is assumed that there is an ext4 partition on the microSD card large enough to cointain the armbian root file system, which is about 900MB.

To mount the .img file, issue the following commands.

sudo kpartx -v -a Armbian_5.91_Sbcspg_Debian_stretch_default_.img

If this operation is completed succesfully, you'll see something like this:

# ll /dev/mapper/
total 0
drwxr-xr-x  2 root root  	80 lug 29 11:52 ./
drwxr-xr-x 21 root root	4440 lug 29 15:50 ../
crw-------  1 root root 10, 236 lug 29 11:41 control
lrwxrwxrwx  1 root root   	7 lug 29 11:52 loop18p1 -> ../dm-0

And then:

sudo mkdir /mnt/tmp
sudo mount /dev/mapper/loop18p1 /mnt/tmp/ -o ro

As root, copy the files from /mnt/tmp/ to the desired partition into the microSD card.

After the copy operation is finished, unmount the microSD card and move it to the target.

To configure the SBCSPG to mount the root file system from this partition, several options are available. The following example shows how the U-Boot environment variables were set to retrieve the Linux kernel image and the device tree blob (DTB) via Ethernet, while the file system is mounted from the microSD card. In practice, an ad hoc variable⁠—named net_mmc⁠—was added:

=> print net_mmc
net_mmc=run loadk loadfdt mmcargs addip addcons addmisc; if run configid_fixupfdt; then bootm ${loadaddr} - ${fdtaddr}; fi
=> edit mmcroot
edit: /dev/mmcblk0p4 rootwait rw

The following section shows the full boot process.
