How to restore the device Hw v2?

[avchizhov]

I have the nRF Hw v2, and it seems like I did something wrong with a Fw:

nRF is recognizable by a computer as the COM10/11/12 device:

Most of the nRF Connect Desktop applications could recognize the device, but, unfortunately, they can not connect to it, and return an error:

or return nothing:

t looks like the Fw Application is loaded on the nRF and it is booted properly, while the modem does not respond.

Is there any Fw for the modem?

I saw some Segger software tool, and it offers to restore some image from time to time. Could it be connected to this problem?

Hi,

Looks like the recover command faild, not sure why, other errors you see are related to APPROTECT being enabled. Try one of the following steps:

Can you test with the use of the command line to nrfjprog, https://www.nordicsemi.com/Products/Development-tools/nRF-Command-Line-Tools/Download , you can use a command called recover, so all you have to do is run "nrfjprog --recover" from a terminal. 

Seems that APPROTECT is enabled witch is stopping you from reading the memory, so a recover command should solve this. You can also do this with nRF UTIL tool, https://www.nordicsemi.com/Products/Development-tools/nRF-Util/Download#infotabs,  then you need to get the devices module and run this command " nrfutil device recover"

Jonathan, greetings.

The nrfjprog --recover returns the next:

And the board still returns a error during the initial setup:

I see that you have a very old DK here.


Did some testing and it seems that the Old DK does not work as expected here. I did test one of my old v1.0.0 DK and the behavior is the same. 

Not sure why that is, will investigate and report infernally.

Jonathan, thank for your reply.

I do not you hurry, but, let me know, if there any workaround here.

Br., Toni.

[JONATHAN LL]

Pleas check the MCU selections switch, it should be on the nRF91 position.

Jonathan

[avchizhov]

Jonathan, the current Sw positions are:

Sw5 = nRF91

Sw1 = N.C.

Sw2 = N.C.

Other Sw (10, 11, 1, 8) are sealed, and are never changed.

Can you share an image of the DK? 

Also have you flashed anything on the nRF52 on the DK ? 


V0.8.3 is also an early engineering sample can you double check that it says B1 on the SiP itself and not B0? Might also be that non of indicators are the if it is an Engineering version. 




Example on B0 and Eng. versions. 

These seem to not work, the modem firmware that these use are not the latest, and the Quick start does use the latest mfw. So I would recommend that you update to a newer DK.

Jonathan, greetings.

That is we have:

Thanks, yes I see you are rocking the Engineering edition. It is not fully tested and does also not support the latest modem firmware fully.  Its discontinued.

If you plan to work with that then you would need to work with the old documentation and releases, might also stumble upon untested issues so I don't recommend that you continue to work with it.
