mipselsf-k3.4: Bus Error

[ChrisLipscombe]

Trying to install Entware while rooting Creality K1 3d printer. Get bus errors. Prevents ffmpeg from being installed when I try to install the timelapse feature.

I am afraid entware team cannot help you. You are using instruction and scripts from here - https://github.com/Guilouz/Creality-K1-and-K1-Max/ - so all the installation questions should go there.

It's looks like there is an issue with latest aarch build of opkg released on February 24: http://bin.entware.net/aarch64-k3.10/installer/

/opt/bin/opkg update
/opt/bin/opkg upgrade

Have stopped to work.

When using an old version of opkg it's working.

[zyxmon]

opkg was not modified for 9 months an was not changed on February - https://github.com/Entware/Entware/tree/master/package/system/opkg

Can't reproduce that on Keenetic Router:

~ # cd /opt/bin/
/opt/bin # mv opkg opkg.bak
/opt/bin # wget -q http://bin.entware.net/aarch64-k3.10/installer/opkg
/opt/bin # chmod +x ./opkg
/opt/bin # ./opkg --version
opkg version d038e5b6d155784575f62a66a8bb7e874173e92e (2022-02-24)

Look like something firmware specific issue. You may find previous version here:

/opt/bin # wget -qO opkg.prev http://bin.entware.net/aarch64-k3.10/installer/prev/opkg
/opt/bin # chmod +x ./opkg.prev 
/opt/bin # ./opkg.prev --version
opkg version f2166a89b7e96e2c60002959731eebc5f45fa318 (2020-05-07)

@ryzhovau My bad, i'm not use aarch version, i use mipselsf version.

It's look like not updated since May 2023 but not working, it worked before.

When I use previous version it's working, don't really understand what's happens with current version.

[ryzhovau]

Looks like some syscall is missed in kernel. Just checked mipsel version on ancient Padavan frimware from 2016, looks fine:

/opt/home/admin # opkg --version
opkg version d038e5b6d155784575f62a66a8bb7e874173e92e (2022-02-24)
/opt/home/admin # uname -a
Linux WT3020H 3.4.113 #1 Wed Oct 16 13:35:50 MSK 2019 mips GNU/Linux

[Guilouz]

@ryzhovau Could this be related to these updated files?

Nothing has changed on the OS, it's a 3D printer (no firmware change, no kernel change).
Installer generic.sh worked before until February 23

[Guilouz]

@ryzhovau

Last error is normal, I have just downloaded opkg.

Any idea what can cause this ?

Linux K1Max-5992 4.4.94 #332 SMP PREEMPT Thu Jan 11 18:56:04 CST 2024 mips GNU/Linux

[Guilouz]

Installer install entware-opt package released on February 24: entware-opt_227000-3_all.ipk

It also replace opkg and it stop to work, I have Bus error with many of my packages.
Previous version was working before, how i can install previous version ?

[dwaite]

I believe this is related to 8ad1c9e , as the Ingenic CPU on this board does not support MIPS16.

[Guilouz]

Yes it use Ingenic x2000E / xburst II Soc

@ryzhovau is it possible to restore this, a big community use it on many Creality printers.

[ChrisLipscombe]

I have been following this thread, but everything is over my head. I hope whatever happened will be fixed. Like Guilouz said, a large community use this on Creality Printers, myself included.

[Kev608]

I also have this problem.

[ryzhovau]

Please, try to install Entware from http://test.entware.net/mipselsf-k3.4. I turned off MIPS16 instruction to make it compatible with Ingenic x2000.

bcm63xx is the only OpenWrt MIPS32 target without MIPS16 extension. Not sure I want to turn it off in favor of few rare devices, sorry.

I'll keep this issue open for a while to reveal similar caces.

[Guilouz]

@ryzhovau it's working ! Is it possible to keep it ?

[ryzhovau]

I’ll keep it for a week, so you'll be able to make your own mirror.

[ryzhovau]

We turned off MIPS16 extension for mipsel-k.4 feed, as it was before Feb 2024.
