nRF Devicetree Visual Editor bug

[Christoffer Brask]

Hi I would like to report a bug in the Devicetree visual editor.

When you add two fixed regulators and connect a separate sensor to each of them, both sensors will be represented above both regulators.

Another question regarding the fixed regulator node. The current SDK (2.6.1) has a bug such that the off-on-delay property is not working, which makes the use of sensor drivers that sits behind regulators useless as at pre kernel, the sensor init will fail as no power is enabled from the regulator. I see that Zephyr 3.6.99 has fixed this. Any timeline on when 2.7 is released which hopefully will use 3.6.99?

Hi,

Can you share your devicetree file where the regulators and sensors are defined?

Any timeline on when 2.7 is released which hopefully will use 3.6.99? 

I am not able to answer questions about our timeline. You can try to ask your local sales representative from Nordic Semiconductor for information about our timeline.

Best regards,
Marte

Hi,

I could reproduce the issue on my side. I have reported it to the developers and will let you know when I have an update.

Best regards,
Marte
