TFM_VERSION_MANUAL mismatches to actual TF-M version. Please update [nRF9160 DK]

[shak2300]

Hi everyone

I am using the nRF9160 DK board with the VS nRF Connect extension.
I am stuck at lesson 7 exercise 1 of the Cellular IoT Fundamentals lesson.

Up to this lesson I have had no problems.

The first error it gave me was that
CONFIG_LTE_PSM_REQ_RPTAU and CONFIG_LTE_PSM_REQ_RAT were not included because CONFIG_LTE_LC_EDRX_MODULE and CONFIG_LTE_LC_PSM_MODULE were not enabled.

After this change, it did not give me any problems for these commands.

The problem comes when I do the build configuration again which gives me the following error in the terminal:

TFM_VERSION_MANUAL mismatches to actual TF-M version.  Please update

I have tried moving the folder to have a shorter path, but the problem persists.

I have searched the community but can't find any help

I have tried moving the folder to have a shorter path, but the problem persists.

I tried updating the firmware with the guide Updating the DK firmware using Programmer, but the error remains

I have also this errors.

I uninstalled and reinstalled the extension and re-performed the instructions in Chapter 1 exercise 1 and 2 of the nRF Connect SDK Fundamentals section

Hi,

The warnings under the PROBLEM tabs can be ignored. It is unfortunate from a user perspective that you get these, but they are not relevant, and for the most part invalid. The warnings and errors you shoudl pay attention to are those printed in the build log which you will se under TERMINAL.

On the terminal I have this fatal Error:

The terminal is shown in the image.
I don't know why but I can't copy and paste, but it says I can't post it.

Hi,

I do not see clearly what caused the error, but the DevAcademy course is not updated for the latest nRF Connect SDK relase (2.8.0), so you should use an older SDK version when going through the course. The content you learn will be equally valid also for newer SDK versions.

PS: Ctrl + C does not work to copy, but you can copy-paste by right clicking and selecting Copy.

I really didn't see that you need an earlier version for these lessons:
Cellular IoT Fundamentals:

Supported SDK versions
nRF Connect SDK v2.2.0 - v2.6.1
nRF Connect SDK v2.5.0 or higher is needed for nRF9161 DK
nRF Connect SDK v2.6.0 or higher is needed for nRF9151 DK

Using v2.6.0 works

Having done nRF Connect SDK Fundamentals which supports v2.8.0 I thought the other lessons have the version I used as support.
