6. Confirm the Image Switch ( newtmgr image confirm )

The final step is to 'confirm' the image update process to make it permanent, which is done via the image confirm

sub-command:

If you check the flags values again, you will see that version 0.2.0 is now 'confirmed' and will continue to execute every

time you reset the device:

$ newtmgr -c serial1 image list

Images:

slot=0

version: 0.2.0

bootable: true

flags: active

hash: 87276847693699896f68b3c26d378648cace2900db4145cd5ade6049ac5ec15a

slot=1

version: 0.1.0

bootable: true

flags: confirmed

hash: be52a255c25546dacc497d62faea910459903a1c1916ce831697d40fc2c20689

Split status: N/A (0)

$ newtmgr -c serial1 image confirm

As of newtmgr 1.1.0 the 'confirm' command will always return "Error: 1", but the confirm process does work, as

verified with the image list command below!



$ newtmgr -c serial1 image list

Images:

slot=0

version: 0.2.0

bootable: true

flags: active confirmed

hash: 87276847693699896f68b3c26d378648cace2900db4145cd5ade6049ac5ec15a

slot=1

version: 0.1.0

bootable: true

flags:

hash: be52a255c25546dacc497d62faea910459903a1c1916ce831697d40fc2c20689

Split status: N/A (0)

If you reset without confirming, the device will revert to the original (0.1.0) image!

Note: You can optionally skip the 'test + reset' phase, and go directly to confirming an image after the upload

is finished by using 'newtmgr -c serial1 confirm [hash]' with the hash of the image to finalize. This is a more

dangerous choice, but the option is there if you wish to save some time.
