Thank you for confirmation, I understood the same initially but your input confused me.

I tried, and looking closer at this, I see that the MCUboot code has expects a DTS GPIO node, while the nPM1300 LED node is of the type "nordic,npm1300-led", meaning that it can not be slotted in automatically.

If you want to use the nPM1300 LEDs from MCUboot, it would require source code changes to MCUboot, similar to how The nPM1300 one button sample sets up its LEDs.

No worries, thank you!!

Yea, I can try myself.
I am at home office today, and don't got the nPM1300 kit here. But will be back in the office tomorrow, so I can try to see if I can do this some time this week.

I was unable to get it working, the sample is not defining anywhere the leds on the device tree separately. I cannot set the allias for led0. Can you please try it your self?

ah cool, thank you! will try out today

MCUboot uses gpio_pin_set_dt.

led_on uses gpio_pin_set_dt

isn't that mcuboot uses gpio api instead of led? how this supposed to work?

The nPM1300 One-Button sample sets up the nPM1300 LED drivers in the application.
Look at how this adds Kconfig options and DTS files for the LED driver.

Then add those to MCUboot overlays, with sysbuild/mcuboot.conf and sysbuild/mcuboot.overlay.

With this, when MCUboot use the LED drivers to toggle the LED, this should automatically use nPM1300 drivers instead.

Yes. A sample dts would be appricated.

Hi,

So you want to know if MCUboot can control the nPM1300 LED Drivers?
