The ESPRESSObin v5 is a small single board computer similar to a raspberry pi. It has 3 ethernet ports, a USB 3.0 port, as well as an internal mPCIe slot.

Build The Image
Use profile meshnode and device espressobin and see Building the Firmware for instructions on using the ImageBuilder.
Flash The Image to µSD
You can locate your micro-sd card by running the following commands:
sudo su fdisk -l
Take not of the output. It should contain something like /dev/mmcblk0. That's your memory card.
The build you ran in the last seciton created a compressed image file for you. The following command unzips the file, and pipes it into the µSD. Replace the things in bold as necessary before running the command.
zcat ./communities/massmesh/meshnode/bin/espressobin/openwrt-massmesh-meshnode-mvebu-cortexa53-globalscale_espressobin-squashfs-sdcard.img.gz | sudo dd of=/dev/mmcblk0
Modify U-Boot Variables
Before the ESPRESSObin will boot our Open WRT image from an SD card, we will need to modify just a few U-Boot variables. More information about this can be found in this commit message and these docs.
In order to connect to your modify ESPRESSObin's U-Boot variables, you'll need to establish a serial connection.
Once you've established a serial connection, change the bootcmd variable using the following command:
setenv bootcmd 'mmc dev 0; ext4load mmc 0:1 $kernel_addr $image_name;ext4load mmc 0:1 $fdt_addr $fdt_name;setenv bootargs $console root=/dev/mmcblk0p1 rw rootwait; booti $kernel_addr - $fdt_addr'
Now, save your changes.
saveenv
Flashing
- Write
openwrt-18.06.2-mvebu-cortexa53-globalscale-espressobin-squashfs-sdcard.img.gzto a microsd card using the following command: - Run
syncbefore removing the sd card - Insert the sd card into the ESPRESSObin and power it on
zcat ~/Downloads/openwrt-18.06.2-mvebu-cortexa53-globalscale-espressobin-squashfs-sdcard.img.gz | sudo dd of=/dev/mmcblk0
