The WHO_AM_I register value does not match the device selected

[TZapp.1]

Hi,

I am using a STEVAL-MKI109V3 mother board to evaluate 2 accelerometers :

• LSM6DSOX (STEVAL-MKI197V1)
• LIS2DUXS12

I want to use the GUI software UNICO v9.14.6.0 but when I want to connect my device, an error popup appear : "ERROR : The adapter board has not been recognized. The WHO_AM_I register value does not match the device selected".

I have updated the motherboard firmware with the v3.48.3 but I still have the problem with my 2 MEMS boards ...

Can someone help me ?

Hi @Federica Bossi​ ,

Thank's for helping me.

Here is the steps I followed :

• Connect my MEMS board (STEVAL-MKI197V1) on the STEVAL-MKI109V3

• Plug it in my computer
• Launch UNICO v9.14.6.0 software and select "STEVAL-MKI197V1" in the Device Name table

• Click on Select Device and here is the error popup

• Click on OK and here is the main window but I still can't connect ..

• Tried to click on connect but same error popup appear
• Tried to go back and select a second time the device name put same error pop-up
• I tried with another MEMS board which is a bit different but it is the same scenario

• I tried with another USB cable but still don't work

I hope my explanations are clear.

Thank's in advance for your help.

Hi @thomas Zapparrata​ ,

You have to change the jumpers' position as I indicated you in the picture below:

I have exactly the same problem but with the LSM6DSV16X (STEVAL-MKI227KA). I can´t see the image of the solution posted. 

Can I get some help?

Hi @FKara.3 , @B3r ,

Please can you share a picture of your STEVAL-MKI109V3? So that I can check if your jumpers are ok.

Thanks.
