Introduction

Sept-20 2022


This single-board computer from SolidRun is interesting for low-cost network applications requiring 10GbE. It has very capable routing performance which can be combined with storage for specialized applications.

I've done some performance testing on the single-shot version (the double-shot version is more powerful) and designed IO Shield and a extension board for ATX cases.

Hardware

MACCH

MACCHIATObin Single Shot- Quad-core 1.6 GHz A8040.

CPU: Marvel ARMADA A8040 Arm® Cortex® A72

Memory: 16GB DDR4 RAM

Built-in storage: 8GB eMMC

Network: Gigabit RJ45, dual 10GbE SFP+, single 2.5Gbe SFP+

Format: Mini-ITX (170mm x 170mm)


This single-board computer (SBC) is used for network applications requiring affordable 10GbE. It has very capable routing performance which can be combined with storage and specialized applications.

Storage and Routing performance

I tested using the SBC as a low-power NAS using 1/5/10 GbE ports on my desktop connected to the 1/10GbE ports on the SBC (no 2.5GbE SFP) with various storage (RAMdisk, NVME SSD, SATA SSD, BTRFS raided HDD) and got following rough top performances:


Routing with iperf3: GbE--GbE: 565 Mbits/sec ~ 68 Mbytes/sec Routing with iperf3: 5GbE--10GbE: 4.61 Gbits/sec ~ 549 MBytes/sec Routing with iperf3: 10GbE--10GbE: 9.08 Gbits/sec ~ 1051 MBytes/sec Storage with rsync, 1G zero file: GbE--GbE: 67.88MB/s Storage with rsync, 1G zero file: 5GbE--10GbE: 337.28 MB/s Storage with rsync, 1G zero file: 10GbE--10GbE: 345.35 MB/s Storage with bbcp, 1G zero file: 5GbE--10GbE: 400 MB/s Storage with bbcp, 1G zero file: 10GbE--10GbE: 400 MB/s


Routing was as expected, and for a single file transfer storage saturates at 5GbE (probably CPU limitation). Multithreaded bbcp was the fastest transfer solution. Not a very scientific test method but hopefully you get a rough understanding.


Note: I have not changed the MTU in these tests.

Instructions

Flash UEFI Boot on SPI flash

The MacchiatoBin comes with TianoCore EDK2 firmware installed on the SPI flash. If the SPI Flash needs to be reflashed, this guide covers flashing the UEFI boot from U-Boot running on MMC.

Download the pre-build SPI flash binary from SolidRun and put it on an USB stick.


# variables: # kernel_addr_r=0x5000000 # filesize=2730940=0x29abbc # start USB stack usb start # load uefi-mcbin-spi.bin to ram load usb 0:1 $kernel_addr_r uefi-mcbin-spi.bin # initialize spi flash sf probe # erase flash sf erase 0 0x400000 # write loaded file sf write $kernel_addr_r 0 0x$filesize

UEFI Boot, Linux Bootloader, EMMC root partition(s)


Why?

I want to utilize the onboard eMMC and use the SBC standalone without an SD-Card but still be able to use an SD-Card as rootfs or secondary storage. First I followed the instructions [3] to use U-Boot installed on eMMC data partition, the board refused to boot. Then tried the eMMC boot0 and boot1, the board refused to boot. Mmc flags looked good, the eMMC content looked good when dumping but still no boot.


New strategy, there is an bootable SPI Flash available with pre-installed Tianocore/EDK2 firmware. For this to work I need a EFI FAT partition and root partition(s). The SPI Flash is too small to fit my kernel image I need so the partitions need to be on the eMMC. We'll use Arch Linux on a MMC to boot and configure the system using the console:


screen /dev/ttyUSB0 115200


Since I'm developing solutions for both Buildroot and Arch Linux I wanted both on the eMMC, obviously other headless EFI/ARM supported OS-combination is possible.


The MacchiatoBin uses a random Ethernet MAC so to enable DHCP usage the MAC addresses will need to be set by the OS. In U-Boot the MAC addresses can be stored in the SPI flash and set by U-Boot before initilizing the kernel but I have not found a way to do this in UEFI boot mode.


Boot Arch Linux from SD-Card (U-Boot)

Prepare an SD-Card with Arch Linux [2] and set the dip switches to SD CARD boot. The gptfdisk package or similar is needed to create a GPT table on the EMMC (fdisk does not support GPT and EFI requires GPT). If the SBC does not have an Internet connection, mount and put it on the SD-CARD.


Boot the MacchiatoBin and prepare the eMMC partitions:


# (Optional) erase previous partition table on EMMC dd if=/dev/zero of=/dev/mmcblk0 conv=notrunc # A 500M+3.4G+3.4G eMMC table would look like this: gdisk /dev/mmcblk0 ----------------------------------------------------------------------------- Number Start (sector) End (sector) Size Code Name 1 2048 1026047 500.0 MiB EF00 EFI system partition 2 1026048 8146943 3.4 GiB 8300 Linux filesystem 3 8146944 15267839 3.4 GiB 8300 Linux filesystem # Formatting mkfs.fat -F 32 /dev/mmcblk0p1 mkfs.ext4 /dev/mmcblk0p2 mkfs.ext4 /dev/mmcblk0p3 # Mount new boot partition to /mnt mount /dev/mmcblk0p1 /mnt # Note: It may be possible to modprobe efivarfs and mount EFI when booting in # U-Boot mode, if so the bootctl should install fully and reboot to Arch on # SD-Card via UEFI would not be needed. I have not tried this: modprobe efivarfs mount -t efivarfs efivarfs /sys/firmware/efi/efivars # Install boot manager bootctl --esp-path=/mnt install # Create EFI entry for the SDCARD /mnt/loader/entries/arch_sdcard.conf ----------------------------------------------------------------------------------- title Arch Linux linux /Image initrd /initramfs-linux.img options root=UUID=5ae6358a-9dfb-4f06-bffe-edbad04c4ad8 rw ipv6.disable=1 loglevel=3 # UUID needs to be replaced to point to rootfs on the SD-CARD. # Copy kernel and initramfs from SD-Card to boot partition cp /boot/Image /mnt cp /boot/initramfs-linux.img /mnt # Unmount umount /mnt # Turn off the board and change dip switches to SPI ROM and restart (cold)


Boot Arch Linux from SD-Card (UEFI)

Now the Tianocore/EDK2 should load and boot Arch Linux via UEFI. Note: For this to work the UEFI boot needs to be flashed on the SPI memory. Instructions.

# Repeat the bootctl installation, the Linux Boot Manager needs an EFI environment to be installed # this was why the reboot was required. mount /dev/mmcblk0p1 /mnt bootctl --esp-path=/mnt install


There is now a functional second-stage EFI bootloader in the eMMC!


Install Buildroot on eMMC partition

This guide assumes you already have a Builroot image, I'm using buildroot/output/images/rootfs.tar

# Buildroot on the second partition mount /dev/mmcblk0p2 /mnt # Extract rootfs.tar in root partition bsdtar -xpf rootfs.tar -C /mnt # Now move the boot image to the EFI partition mv /mnt/boot /mnt/boot2 mkdir /mnt/boot mount /dev/mmcblk0p1 /mnt/boot mkdir /mnt/boot/buildroot mv /mnt/boot2/Image /mnt/boot/builroot/ mv /mnt/boot2/armada-8040-mcbin.dtb /mnt/boot/builroot/ genfstab /mnt >> /mnt/etc/fstab # Should look something like this /mnt/etc/fstab ----------------------------------------------------------------------------------------- /dev/mmcblk0p2 / ext4 rw,relatime 0 1 /dev/mmcblk0p1 /boot vfat rw,relatime 0 2 proc /proc proc defaults 0 0 devpts /dev/pts devpts defaults,gid=5,mode=620,ptmxmode=0666 0 0 tmpfs /dev/shm tmpfs mode=0777 0 0 tmpfs /tmp tmpfs mode=1777 0 0 tmpfs /run tmpfs mode=0755,nosuid,nodev 0 0 sysfs /sys sysfs defaults 0 0 efivarfs /sys/firmware/efi/efivars efivarfs defaults 0 0 # Now add the boot entry /mnt/boot/loader/entries/buildroot_emmc1.conf ----------------------------------------------------------------------------------------- title Buildroot (EMMC) linux /buildroot/Image devicetree /buildroot/armada-8040-mcbin.dtb options root=/dev/mmcblk0p2 rw ipv6.disable=1 loglevel=3 # Note, mounting or using UUID caused boot issue. # With buildroot the MAC addresses can be set in the interface file # and this example uses a mix of fixed and dynamic IPs /mnt/etc/network/interfaces ----------------------------------------------------------------------------------------- auto lo iface lo inet loopback auto eth0 iface eth0 inet static hwaddress ether a6:23:92:c6:58:52 address 192.168.50.2 netmask 255.255.255.0 gateway 192.168.50.1 auto eth1 iface eth1 inet static hwaddress ether 62:e0:da:14:8c:70 address 192.168.50.3 netmask 255.255.255.0 gateway 192.168.50.1 auto eth2 iface eth2 inet dhcp hwaddress ether 42:f8:49:92:fc:65 auto eth3 iface eth3 inet static hwaddress 02:a2:3a:5c:ee:ee address 192.168.50.4 netmask 255.255.255.0 gateway 192.168.50.1 -------------------------------------------------------------------------------------- When done, unmount the buildroot partition umount -R /mnt


Now the SBC should have a working Buildroot installed on eMMC partition 2.


Install Arch Linux on eMMC partition

Return to Arch Linux on the SD-Card to setup the eMMC version. Some tweaks necessary but mostly using the Arch Linux installation guide [4].


# Arch Linux on the third partition mount /dev/mmcblk0p3 /mnt # Note: # I don't mount the boot partition but instead add files to # /boot manually at this point. # Install base system on third partition pacstrap /mnt base linux linux-firmware wget nano ethtool # Adjusting where mkinitrd places the initrd, change default_image # in /etc/mkinitcpio.d/linux-aarch64.preset, example default_image="/boot/archlinux/initramfs-linux.img" fallback_image="/boot/archlinux/initramfs-linux-fallback.img" # Now initramfs-linux-fallback.img and initramfs-linux.img will end # up in /boot/archlinux/ when reinstalled. # Now mount the boot partition and copy default files to archlinux # subdirectory. mv /mnt/boot /mnt/boot2 mkdir /mnt/boot mount /dev/mmcblk0p1 /mnt/boot mkdir /mnt/boot/archlinux mv /mnt/boot2/* /mnt/boot rmdir /mnt/boot2 # Pacstrap will still copy firmware and kernel image files to /boot # when upgrading so I usually block these packages in /etc/pacman.conf # and upgrade these manually when needed and move them manually. # This can be done automatically using pacman hooks, not covered here. # Now the fstab genfstab /mnt >> /mnt/fstab # Should look something like this /mnt/etc/fstab ----------------------------------------------------------------------------------------- /dev/mmcblk0p3 / ext4 rw,relatime 0 1 /dev/mmcblk0p1 /boot vfat rw,relatime 0 2 # EFI boot entry /mnt/boot/loader/entries/arch_emmc2.conf ----------------------------------------------------------------------------------------- title Arch Linux (EMMC) linux /archlinux/Image devicetree /dtbs/marvell/armada-8040-mcbin-singleshot.dtb initrd /archlinux/initramfs-linux.img options root=/dev/mmcblk0p3 rw ipv6.disable=1 loglevel=3 # Now chroot to target arch-chroot /mnt # For networking to work, the marvell module needs to be loaded, add MODULES=(marvell marvell10g) # to /mnt/etc/mkinitcpio.conf and execute mkinitcpio -P # Set root password passwd # systemd-networkd can be configured to support static MAC /etc/systemd/network/30-eth2.link --------------------------------------- [Match] OriginalName=eth2 [Link] MACAddress=42:f8:49:92:fc:65 /etc/systemd/network/30-eth2.network --------------------------------------- [Match] Name=eth2 [Network] DHCP=yes IPv6PrivacyExtensions=yes [DHCPv4] RouteMetric=512 [DHCPv6] RouteMetric=512


Now the SBC should have a working Arch Linux installed on eMMC partition 3.


Success

There should now be two OS installed with a interactive UEFI boot loader.
