STEVAL MKI109V3 does not recognize other STEVAL adapters

[AngeloB]

HI,

My MKI 109V3, even after firmware update, does not recognise adapters MKI197V1 or MKI212V1 (The WHO_AM_I register value does not match the device selected).

I tried on two different laptops with windows 10.

What am I doing wrong?

thank you in advance

Hi @AngeloB ,

Welcome to ST Community!

Can you share some screenshoots of your steps in Unico and photos of your setup?

Thanks,

Hello,

Today I tried also with windows seven and related ST driver for com port, same error.

Currently, using another board MKI109V3 found in the office (at least 2 years old and updated with the new fw), everything seems work fine. I don't know what to say, It seems a problem between board HW version and adapters

Ciao @AngeloB ,

This sounds strange. I tried both a MKI197V1 and a MKI212V1 and they work properly.

If you have a multimeter, can you check if you see 1.8V referred to GND on both VDD and VDDIO pins? you can use the VDD pin directly on the adapters.
