@francisco-vieira I wonder if the issue is that the port handshaking is up the spout. Try fixing the device using sane command. Sane doesn't fix hardware handshaking but it can fix software handshaking (xon/xoff).
You need to install coreutils-stty, then you can run the command:
stty -F /dev/ttyS0 115200 sane (115200 may not be the correct baud rate for your device)
If that doesn't fix it then look at what loadable modules may be attached to the device (lsmod) try unloading the module (rmmod) then reload the module (insmod) and see if sanity is restored.
From the blog post:
What if I need units now?
Visit our distributors Mouser and Digikey – they will continue to sell Omega2 devices in small and large quantities with immediate shipping.
Unfortunately, they’re both out of stock of the Omega2+ (OM-O2P) at the moment. We’re working to resupply them, currently estimating an April timeframe.
To find direct links for Onion products on our distributors’ sites, see our new How to Buy page (https://onion.io/buy)!
@maxromanovsky Short Answer: It doesn't affect the Omega2
MIPS (the company) has stopped developing new MIPS CPU architectures. But that doesn't affect existing MIPS architectures (like the MIPS 24KEc in the Omega2's CPU).
CPUs based on existing MIPS architectures will continue to work (no reason why they wouldn't). Software support for MIPS architectures will also continue for quite some time because there's so many MIPS-based CPUs out there in the wild.
@IOTrav I don't use Node-red but try the command logread from the console, I expect errors are logged to the system log and you can use grep to filter the logs.
Others may be able to provide better advice specific to Node-Red
