GoHeishaMon crashes when writing to /dev/ttyUSB0

[burt2902]

GoHeishaMon 1.0.166 successfully installed on CZ_TAW1 with the following changes to the default config:

MqttServer="192.168.1.2"
MqttPort="1883"
MqttLogin="aquarea"
MqttPass="REMOVED"

Mosquitto server running on 192.168.1.2 receives all messages from other clients but receives only one connection attempt from GoHeishaMon-Pub client and no messages. The only connection attempt happens soon after each CZ_TAW1 reboot.

LuCi is accessible. System log indicates a crash...

Furthermore, the same system log does not indicate creation of /dev/ttyUSB0 device. The crash doesn't occur if GoHeishaMonConfig.new Device is set to "/dev/ttyS0" which exists.

CZ_TAW1 hardware update requiring a different USB serial kernel driver?

Turned out that pl2303 usb-serial module is too old for the updated chip in my CZ_TAW1. New chip requires support for 23a3 product id which has been added in 5.x kernel series.

@lsochanowski: I'll be happy to make new CZ_TAW1 working and I have few questons:

1. Which openwrt version is GoHeishaMon baesd on?
2. Was kernel a stock one or compiled from sources?
3. If it was compiled from sources, how can I reproduce the dev env to be able to build patched pl2303 module?

[wolnypl]

Hello, First of all, @lsochanowski thanks for your project. I'm interested in it a lot.

I have exactly the same error message o newly-bought cz-taw1 as burt2902

I'm also interested with answer to above questions or any other suggestions how this could be fixed.

Any progress on this issue? New cz-taw1 devices do not work with current version.

[lsochanowski]

Hello i've ocerlooked that now i'am processing the issue ;)

[sauliuslt]

Hello i've ocerlooked that now i'am processing the issue ;)

Thanks! I hope this is easy fix.

[lsochanowski]

ok like you all say , we need to upgrade the core system , (openwrt) , i don't have new system , we need to extract it in the way we do it before (by locing upgrade mechanism and let orginal taw to download file but not to install ) when we get it we can replace wrt here in repo

[lsochanowski]

https://github.com/lsochanowski/GoHeishaMon/tree/NoWebSerwerButtonsAndLED/OS < here is whole openwrt we use today problem is i don't have the pump or taw anymore we need someone with that hardware to process the case

[sauliuslt]

How can we help? I have new cz-taw1 with pump. Can you give instructions how to download taw from device?

[MiG-41]

@lsochanowski ,@sauliuslt , here is kernel : https://www.mediafire.com/file/5ray9x0d70gjytu/openwrt-ar71xx-generic-cus531-16M-kernel.bin/file , and filesystem: https://www.mediafire.com/file/gaqaqff8h9u3jak/openwrt-ar71xx-generic-cus531-16M-rootfs-squashfs.bin/file Orginal for CZ-TAW1 from September 2022 , a2wmain version 03.04.02 You can try to use only the kernel from it....

[MiG-41]

What is showing "cat /sys/kernel/debug/usb/devices" command:? , since at my it is: `root@OpenWrt:/# cat /sys/kernel/debug/usb/devices

I cannot access device via ssh, only luci web admin is working for me.

[MiG-41]

Here is the newest orginal fw with a2wmain version 04.01.03 : https://www.mediafire.com/file/9z3ewl5g1aqqgk0/download_file.tgz/file

You can try to flash it , it will be orginal FW , if this will work with Service Cloud (connecting ,ect) , then it is included new drivers ,case will be only to upload GoHeishaMon there instead a2wmain....

[sauliuslt]

Uploaded this FW and it works perfectly.

[MiG-41]

You uploaded it with sysupgrade as well (so booth files ) and Smart/Service Cloud works perfectly , or you upload only Kernel file with GoHeishamon sysupgrade file , and GoHeishamon works perfectly ?:)

[sauliuslt]

I uploaded both files from your archive file and smart could works fine. I can try different combination, but you have to tell me what exact files to upload.

[MiG-41]

Probably this not helps.... @lsochanowski are you able to complile GoHeishamon taking as tamplate latest orginal files ? I uplated some of them , but it is not compiling automaticly any more...

[lsochanowski]

on it @MiG-41

[lsochanowski]

fixed @MiG-41

[MiG-41]

@lsochanowski maybe you are ale to update all files from nawet orginal squash file? Since i update only pl2303.ko (hoping that this will be ok,but to be sure would be better to update all...

[MiG-41]

Anyway i tried newest 1.0.187 from @lsochanowski , and it run's ( so at least it will not stuck). It has changed/updated driver for pl2303 , so there is a chance ,that will ork , so @sauliuslt ,please try it.

[sauliuslt]

Uploaded latest files, but i don't see any messages. I suspect it did not read config file because after flashing FW white LED was solid and never turned off as in previous versions. I still cannot ssh " Connection refused" so i cannot check any logs.

[sauliuslt]

Any advice on this issue? I wonder why ssh connection is refused?

[burt2902]

@sauliuslt, you need to have ssh server enabled but it is disabled until you perform a first boot procedure. Luckily, there is a way to spawn the ssh server via MQTT as I have described here. Make sure goheishamon is running and sending/responding to MQTT commands. Since it was crashing for me due to lack of /dev/ttyUSB0, I had to modify the config file and change the device to /dev/ttyS0 first. Hope this lets you move forward.

[MiG-41]

Try this one: https://www.mediafire.com/file/c2ac2ls56fhzxbz/GoHeishaMon1.1.191z166.zip/file It should have new kernel , so hopfully support PL23a3 .

[burt2902]

Thank you for getting the kernel updated to support PL23a3.

PS: I will wait with closing the issue until there is an official release containing this change. I believe it would also make sense to update README.md to point at a release supporting newest CZ_TAW1 hardware.

[MiG-41]

@burt2902 so i understand ,that ou test it and it is working On your CZ-TAW1, have mqtt topics ,ect ?

[burt2902]

Yes, confirming that the issue is fixed with the kernel that properly handles 23a3 USB serial chip

Same problem with me. Did you solve it?
