Common newtmgr Commands

The following commands are commonly used when doing day to day development and debugging with Mynewt based

devices:

Display Scheduler Task Activity via 'taskstat'

You can also test the connection with newtmgr using the taskstat command, which will list some basic statistics

about the tasks running in the task manager.

Enter the following command:

Which should give you the following task statistics (output will vary depending on the Mynewt application that is

running at the time):

Uploading Application Images with newtmgr

If you don't have a Segger J-Link or similar debugger, the newtmgr tool can be used to upload an application image

to the secondary bank of flash memory, and then switch application images during the next reset. This allows you to

perform field updates over an inexpensive serial connection with no external HW required.

1. Build the Target Application ( newt build )

The first step is of course to build the target application that you wish to deploy. The default

bleuart (https://adafru.it/yAh) project is used in this case:

$ newtmgr -c serial1 image list

Images:

slot=0

version: 0.1.0

bootable: true

flags: active confirmed

hash: be52a255c25546dacc497d62faea910459903a1c1916ce831697d40fc2c20689

Split status: N/A (0)

The image shown above is the default image that the nRF52 Pro ships with
