Issue installing Entware on NAS540 from Github wiki

AFAIK the version string is major.minor(deviceid.revision)C0. That C0 is always C0, although it can be something different for a router, or something like that. Each NAS model has it's own deviceid, so the difference between V5.21(AATB.6)C0 and V5.21(BHAG.6)C0 can be NAS540 and NAS542.

(The deviceid is stored in flash, as part of the bootloader environment. When flashing firmware the flash script checks the stored deviceid against the id in the new firmware, and if it doesn't match, it errors out. It is possible to change the stored id to cross-flash firmwares. Of course you should only do that if you know what you are doing)

What is the output when you run (as root)

sh -x /i-data/.system/zy-pkgs/entware

Hm. The instructions seem a bit faulty, to me. It's based on the start script /etc/init.d/zypkg_controller.sh, which does (on firmware V5.21(AASZ.0), but it has been this way since firmware 5.00) among other actions:

        # - start to startup packages according to ${USRPKG_DEPS_START}
        while read zypkg; do
                bname=`basename ${zypkg}`
                zypkg=${ZYPKG_PKG_SRC_PATH}/${bname}
                Processed_Packages=${Processed_Packages}:${bname}
                write_log "- starting package \"${bname}\" ..."
                #ckeck ZYPKG_DEPS format
                CHKVERSION=`grep "/i-data/" ${zypkg}`
                if [ "$?" != "0" ]; then
                        PKGVOLPATH=`grep ${bname} ${PKGSTATUSFILE} |grep "Installed-Rule" |awk -F":" '{print $2}' |sed 's/\/
$//g' |sed 's/ //g'`
                        zypkg=${PKGVOLPATH}/etc/init.d/${bname}
                fi
                if [ ! -x ${zypkg} ]; then
                        write_log "---> Error: start-up program \"${zypkg}\" is not existed or not excutable"
                else
                        ${zypkg} startup
                        if [ "$?" == "0" ]; then
                                write_log "---> start \"${bname}\" successfully."
                        else
                                write_log "---> start \"${bname}\" failed."
                        fi
                fi
        done < ${USRPKG_DEPS_START}

As you can see ${USRPKG_DEPS_START} doesn't need to be executable, as the wiki states, though it doesn't hurt either. The entware script needs to be executable (if [ ! -x ${zypkg} ]; then error), which I can't find back in the wiki.

The script loops through all lines in USRPKG_DEPS_START, strips the directory from it, and puts /i-data/.system/zy-pkgs/ before it. If that file exists, and is executable, and contains the string '/i-data/', it's executed with the argument 'startup'.

You can add several lines for several scripts.

I wouldn't know how.

You can try to restart the package system by hand (as root), to see if it spits some errors.

Stop the packages with

/etc/init.d/zypkg_controller.sh stop

And then start with

/etc/init.d/zypkg_controller.sh start
