WIP: My OpenWRT Setup for the PC-Engines APU2
This is my personal Setup/Image for a OpenWRT installation on the APU2 with docker. Why? Because the apu has more than enough power to also run traefik and pihole along with OpenWRT and function as ingress node for my small home cluster. The image has all the APU2 + WLE600VX specific packages installed. It's also compiled with the following settings:
CONFIG_DOCKER_KERNEL_OPTIONS=y
CONFIG_DOCKER_NET_ENCRYPT=y
CONFIG_DOCKER_NET_MACVLAN=y
CONFIG_DOCKER_NET_OVERLAY=y
CONFIG_DOCKER_NET_TFTP=y
CONFIG_DOCKER_RES_SHAPE=y
CONFIG_DOCKER_SECCOMP=y
CONFIG_DOCKER_STO_BTRFS=y
CONFIG_DOCKER_STO_EXT4=y
CONFIG_KERNEL_DEVMEM=y
CONFIG_TARGET_OPTIMIZATION=”-Os -pipe -march=btver2“
- PC Engines APU 2
- WLE600VX Wifi card
- OS: 16 GB mSATA SSD (Don't use a SD card, the mSATA SSD is way faster)
- Persistent data: USB / SD-Card / S-ATA
- Serial to USB adapter (Setup)
- USB stick >= 4 GB (Setup)
This is only a very brief instruction on how to setup the apu for a more detailed description see the official install guide.
Get a serial to USB adapter and a USB stick, install TinyCore to it and copy the image on the stick. (You may also want to update your BIOS, if so follow this guide ) Plug the stick into the apu and connect it via the USB to serial adapter with your PC, but don't power the apu on yet. Open a Terminal and type:
screen /dev/$(dmesg | grep -o -e "ttyUSB[[:digit:]]$") 115200,cs8
Now power on the apu, on the Terminal you should now see the apu booting TinyCore. Once booted enter the following in TinyCore
gzip -dc /openwrt-x86-64-combined-squashfs.img.gz | sudo dd status=progress bs=8M of=/dev/sda
When finished reboot and unplug the TinyCore Stick, OpenWRT is now reachable via SSH on 192.168.1.1 on the LAN interface (eth1), for convenience you may now switch to SSH.
This is mainly a documentation for myself on how I set everything up.
Enter passwd you'll be prompted for a new password
Type fdisk /dev/sda
Press p to print your partition table, it should look like this:
Disk /dev/sda: 14.94 GiB, 16013942784 bytes, 31277232 sectors
Disk model: SATA SSD
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x423b062f
Device Boot Start End Sectors Size Id Type
/dev/sda1 * 512 41471 40960 20M 83 Linux
/dev/sda2 41984 513023 471040 230M 83 Linux
Now press n to create a new partition press Retrun 4 times to use the default value, this will create a partition filling up all unassinged space.
Press p again to print your partition table, it should now look like this:
