Openwrt installation

Lomorage setup using opkg packages with Entware repository (need dependencies in Entware, like ffmpeg exif-tools).

This is currently in Beta, please reach us if you have any problem.

Quick Start

This is for users who want to setup Lomorage using opkg packets.

1. Install Entware

Follow the instruction to install Entware on target machine.

You can use cat /proc/cpuinfo to check the architecture:

root@OpenWrt:/mnt/sda1# cat /proc/cpuinfo
system type		: Atheros AR9344 rev 2
machine			: Western Digital My Net N750
processor		: 0
cpu model		: MIPS 74Kc V4.12
BogoMIPS		: 278.93
wait instruction	: yes
microsecond timers	: yes
tlb_entries		: 32
extra interrupt vector	: yes
hardware watchpoint	: yes, count: 4, address/irw mask: [0x0ffc, 0x0ffc, 0x0ffb, 0x0ffb]
isa			: mips1 mips2 mips32r1 mips32r2
ASEs implemented	: mips16 dsp dsp2
Options implemented	: tlb 4kex 4k_cache prefetch mcheck ejtag llsc dc_aliases perf_cntr_intr_bit nan_legacy nan_2008 perf
shadow register sets	: 1
kscratch registers	: 0
package			: 0
core			: 0
VCED exceptions		: not available
VCEI exceptions		: not available

If it's MIPS, you can use lscpu to check the byte order, mips is a big-endian mips architecture,. mipsel is a little-endian mips architecture.

root@OpenWrt:/mnt/sda1# lscpu | grep "Byte Order"
Byte Order:          Big Endian

And use uname -a to check Linux version:

root@OpenWrt:/mnt/sda1# uname -a
Linux OpenWrt 4.14.221 #0 Mon Feb 15 15:22:37 2021 mips GNU/Linux

Most likely you need mount USB drive and use that for packages installation, refer to:

Make sure you change "/etc/profile" and add /opt/bin/go/bin:/opt/bin in PATH and /opt/lib/ in LD_LIBRARY_PATH

Once you have Entware setup ready, install dependencies and tools from Entware repo:

root@OpenWrt:~# opkg install coreutils-stat perl-image-exiftool ffmpeg ffprobe lsblk

2. Install Lomorage

Architectures supported are:

aarch64-3.10    # arm64, linux kernel ver >= 3.10
armv7-3.2       # armv7, linux kernel ver >=3.2
mips-3.4        # mips big-endian, linux kernel ver >=3.2
mipsel-3.4      # mips little-endian, linux kernel ver >=3.2

Add src/gz lomorage https://lomostaging.lomorage.com/opkg/[architecture] in /opt/etc/opkg.conf, replace [architecture] with those listed above, for example if it's mips big-endian, linux kernel ver >=3.2, use src/gz lomorage https://lomostaging.lomorage.com/opkg/mips-3.4. This should below "entware" entry because some packages in entware are not compiled with needed flags, and need to be overridden.

root@OpenWrt:~# cat /opt/etc/opkg.conf
src/gz entware http://bin.entware.net/mipssf-k3.4
src/gz lomorage https://lomostaging.lomorage.com/opkg/mips-3.4
dest root /
lists_dir ext /opt/var/opkg-lists
arch all 100
arch mips-3x 150
arch mips-3.4 160

And then you can install "lomo-backend", all the dependencies should be able to be installed automatically:

root@OpenWrt:/mnt/sda1/# opkg update --no-check-certificate
root@OpenWrt:/mnt/sda1/# opkg install lomo-backend --no-check-certificate

"lomod" will start automatically after installation, the mount directory is default to "/mnt" and port default to "8000", you can also run:

root@OpenWrt:/mnt/sda1# /opt/etc/init.d/lomod
Usage: /opt/etc/init.d/lomod {start|stop|restart}

Should be notice that for "arm" architecture, it will has two versions: "hf" and "nohf", "hf" means hard float, you can check whether the CPU supports hard float by grep "fpu" /proc/cpuinfo and if it shows fpu : yes then it supports hard float. And if it doesn't support hard float, you should install the following packages instead:

root@OpenWrt:/mnt/sda1/# opkg install lomo-backend_nohf --no-check-certificate

Then you can add cron job to update lomo-backend at 4:00 am everyday:

root@OpenWrt:~# crontab -e

and add the following item:

0 4 * * * opkg update --no-check-certificate && opkg install lomo-backend --no-check-certificate
