Can probably skip this at the top as the problem seems to be with a command filling and growing swap.page with null.

Did not duplicate /overlay as the stuff that would be moved to the flash drive is not showing up, so no reason to duplicate it

/overlay/upper/mnt/swap.page is continuously growing, which reached ~200 meg again causing reboot loop and read-only file system.

Assumed this was swap for ram, but apparently not.

Found the source of the growth, but do not understand why it is doing it. The 2+ is not running that command and cant find that file on 2+ at all.

Was going to copy the old swap.page back on and see how it behaves. Did not try that as the problem seems to be a growing zeroed out swap.page file

@Jason-Gong, I can't find full datasheet about NS107S and information about latency. First, I think the latency of Data and Clock lines are not aligned and it's different. Second, why you think 24MHz is not too much for these? In the datasheet of wrote: "Oscillator Frequency: 30MHz" but what does it mean?

I think you should decrease frequency if it's imperceptibly for eye. Next you can use SPI de-multiplexing for more parallel channels. It's not easy way but stable.

@Landon-Lin Just for reference, Omega1 and Omega2 can't do Node-Red without booting from external storage. Omega2+ has an onboard microSD card. You can configure it to boot from the SD card as in here https://docs.onion.io/omega2-docs/boot-from-external-storage.html (though the instructions don't match up well with current products). But the App Manager will still say Node-Red is incompatible with Omega2+. End-run around that using:

opkg install oos-app-nodered

No more storage issues but SD card is inherently unreliable so eMMC recommended for production as in the Omega2+ Pro. At least it does start up, haven't actually run any flows yet.

@ster-ri hello, they do have a python api that allows access via python. you might find more help with your project here,

I answer myself:
possible solution:

iptables -t nat -A PREROUTING --dst YOUR_LOCAL_IP -p tcp --dport 1880 -j DNAT --to-destination 192.168.3.1

@Valeri-V Thanks for the trick!!!

@Ryan-Pedersen
The error does occur after random time and it happens for a bare system solely installing the Linux system installed on the Onion-2s module. I have tested this for several modules and seems to be systemic for my boards.
It looks like the jffs2 is corrupted during kernel idle . There is no power interruption but despite of that, the operation fails.

Again, all inputs to debug this further is very welcome.

Thanks in advance

I realized a GSM module with Omega 2+, maybe this can help you:
https://github.com/AlbertoZandara/Onion-GSM-Module

Any news? I also have the same questions and still no answer

@Lazar-Demin thank's, finally i did discover what you said..
By the way, it also changed the syntax in some libraries, such as the serialport, and to achieve the complete update, I was forced to expand the RAM memory, otherwise the installation of NPM modules, it is not possible.

Maybe you have to say that, and we will not lose so much time.

thanks
