550uA usually means that the HFCLK is running. The HFCLK will run when something (peripheral) needs it. You need to find out what is using it, unfortunately neither the HW or the SW is able to tell yo

#nrf52480 Calling a function not compiled as part of Zephyr from within Zephyr

Hi Jamie, You might want to take a look at how MCUboot invokes the reset vector in an NVIC table after having found the image: https://github.com/runtimeco/mcuboot/blob/master/boot/zephyr/main.c#L53 A

Hi There is a platform_whitelist in the sample.yaml file. In your case: "platform_whitelist: frdm_k64f " So you need this nxp board or have to port the sample to another board. Greetings Serafin

Hi. It looks that you have HFCLK running all the time. This is probably caused by small issue in power management code. Please try to remove the calls to nrf_power_task_trigger() from soc/arm/nordic_n

Hi Ryan, The UART driver itself uses the GPIO driver internally so I don’t think there should be any issues with your usecase. Regards, Carles From: <devel@...> on behalf of Ryan E

Hi Josef, There is no maximum, neither as a central nor as a peripheral, nor combined. Whatever you can fit in RAM and in multiplexed time (depending on connection intervals, use of slave latency, etc
