Synology ds213j optware manual bootstrap guide.
Introduction
Actually there's no xsh bootstrap for the ds213j (Marvell Armada 370 ARMv7l) although the existing Marvell Kirkwood mv6281 binaries "are ~ compatible" (http://ipkg.nslu2-linux.org/feeds/optware/cs08q1armel/). So this is a small guide to setup manually the optware environment (ipkg, PATH and init scripts).
Note on compatibility
It appear that binaries aren't that much/all compatible. The reason must be that the cs08q1armel toolchain doesn't have updated materials. If you encounter issues you should consider setup a chroot environment instead.
Note on Debian chroot alternative
You must use the --arch=armel deboostrap option and not armhf! This is because the ARMv7l doesn't have the thumb-2 feature which is required by the armhf architecture (reference: https://wiki.debian.org/ArmHardFloatPort#Minimum_CPU_.26_FPU)
Steps
The chroot filesystem is built on a alternate machine (your desktop, laptop, etc, ...) and then uploaded on the synology device where the "second stage" is proceeded.
# Build initial chroot filesystem
$ sudo debootstrap --foreign --arch=armel stretch @debian # build chroot filesystem into the current dir as ./@debian
$ sudo tar czvf @debian.tgz @debian/ # build an archive
$ scp @debian.tgz <user>@<remote>: # upload the archive into synology device
# Second stage (on the synology device)
$ tar xvf "/volume1/homes/<user>/@debian.tgz" -C /volume1/ # unpack
$ chroot /volume1/@debian /debootstrap/debootstrap --second-stage # trigger deboostrap "second stage"
Create optware root directory
$ mkdir /volume1/@optware $ mkdir /opt $ mount -o bind /volume1/@optware /opt
Setup ipkg
$ feed=http://ipkg.nslu2-linux.org/feeds/optware/cs08q1armel/cross/unstable $ ipk_name=`wget -qO- $feed/Packages | awk '/^Filename: ipkg-opt/ {print $2}'` $ wget $feed/$ipk_name $ tar -xOvzf $ipk_name ./data.tar.gz | tar -C / -xzvf - $ mkdir -p /opt/etc/ipkg $ echo "src cross $feed" > /opt/etc/ipkg/feeds.conf

Set PATH
Add the following line to /etc/profile:
PATH=/opt/bin:/opt/sbin:$PATH
Create init scripts
The following steps will allow to automatically bind the /volume1/@optware directory to /opt and trigger the /opt/etc/init.d/* scripts.
Create the /etc/rc.local file (chmod 755) and insert:
#!/bin/sh # Optware setup [ -x /etc/rc.optware ] && /etc/rc.optware start
Create the /etc/rc.optware file (chmod 755) and insert:
#! /bin/sh if test -z "${REAL_OPT_DIR}"; then # next line to be replaced according to OPTWARE_TARGET REAL_OPT_DIR=/volume1/@optware fi case "$1" in start) echo "Starting Optware." if test -n "${REAL_OPT_DIR}"; then if ! grep ' /opt ' /proc/mounts >/dev/null 2>&1 ; then mkdir -p /opt mount -o bind ${REAL_OPT_DIR} /opt fi fi [ -x /opt/etc/rc.optware ] && /opt/etc/rc.optware ;; reconfig) true ;; stop) echo "Shutting down Optware." true ;; *) echo "Usage: $0 {start|stop|reconfig}" exit 1 esac exit 0
