Problem when Flashing mesh_demo sample
When I have seen that error the first thing I try is running the command “ nrfjprog -r” this should successfully reset your board, if it doesn’t then you have a hardware problem, check your connection

Adding an out of tree driver
Adding an out of tree board is easy, I just set the variable BOARD_ROOT and the build system happily finds my_custom_board. This is nicely described by following the links from here: https://docs.zeph

MCUMGR - sends responses to wrong port
Hi Charles, I tried your suggestion, unfortunately it doesn’t help. Every dts that uses mcumgr, also has the console on the same port, there is no existing board that routes the mcumgr to a different

Dear All: I am trying to setup mcumgr to allow code download over a serial port and use the shell. In this case I have 2 serial ports in play. The first serial port is where printk() sends messages. I

Sensor Driver - Synchronous calls to sensor_sample_fetch() and sensor_channel_get()
Dear All: I have finally gotten around to writing a driver for the lsm9ds1 sensor. Boy have I learned a lot about the core of the Zephyr kernel and sensor sub-system, and in general I really like it.

Consequences of relying on 64 bit uptime
The function k_uptime_get() returns time in milliseconds, since this is a 64-bit number (63-bits if you use signed math), it will almost never wrap (well, once every 292 million years, but as far as I
