Writing DQs with node-red-node-intel-gpio causes constant output of 1

[rifelipe]

Dear colleagues,
As described on the IOT2000 Forum there is an issue regarding setting the digital outputs with node-red using the preinstalled nodes. The provided flow seems to be working fine upon start/reboot of the iot2040. As soon as a further "deploy" is done in node-red, the error can be triggered. In this case the digital outputs are then constantly set to 1 and never return to 0.
To reproduce, use the example Image V3.1.1 (available on SIOS) together with the flow provided in attachment.
flows (9).zip.
In node-red, The debug window shows changing values 0 and 1 every 2 seconds:

Wire e.g Digital Output 0 directly to Digital Input 0 on the I/O Shield, or use a secondary device with a DI.
When reading the Digital Input 0 in a loop using mraa, the value will be changing between 0 and 1 as intended (example code available in attachment.) read-di-test.zip

After re-deploying the flow in node-red, the value will remain at 1 constantly.

Recommended customer to try with a different delay time and error appears to be gone for me at least... Waiting for customer feedback. Will leave the issue open until we get a response...

Sounds like siemens/meta-iot2050#57 -> #166. Didn't make it into the last release IIRC.
