MKI197V1 support for MKI109V2 (eMotion)

[Balázs VARGA]

Hi,

I have an MKI197V1 breakout module for the LSM6DSOX sensor. The product page states that it should be supported by the MKI109V2 eMotion board (in fact, it is one of the recommended evaluation boards for this sensor):

https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mems-motion-sensor-eval-boards/steval-mki197v1.html#overview

However, Unico GUI gives me this message:

I have the latest version of Unico (V9.3.0.0, Windows) and the board is flashed with the latest firmware that came with Unico (eMotionV5.0.27_C3.dfu). The creation date of the DFU file is April 2018, so the lack of support is not surprising. Is there a newer firmware to be found somewhere?

Any help is greatly appreciated.

Hi @Bal�zs VARGA​ , in the page you linked, under the title "key features", this statement is reported:

>> Changing the resistor settings is also compatible with the STEVAL-MKI109V2 motherboard

In order to make MKI197V1 compatible with MKI109V2, you have to de-solder R1, R3, R5 and R7 and solder R2, R4, R6, R8 resistors

Eleon, thank you for your quick reply. My resistors are already fitted the way you described. I probed all data pins, and there is complete silence, it looks like the board doesn't even attempt to communicate with the sensor, it just immediately reports back that it is not supported. If I select a different sensor in Unico GUI, I see traffic on the data pins as the board reads the WHO_AM_I register.

The firmware used to be open source, and I have found the code in an older Unico installer (the firmware version is the same). Please take a look at these code lines:

It really looks like there is no support for the 197v1 adapter board. Just to be sure, I opened the firmware binary with a hexeditor, and indeed, it contains all of the strings above, but not "197V1".

Are you sure there isn't a newer firmware than the one that comes with Unico?

[Balázs VARGA]

I discovered that it's possible to fetch the list of supported devices via the serial port. Indeed, MKI197V1 is not listed.

So we have one of the recommended development boards (that's not exactly cheap, but unavoidable, since Unico GUI will only communicate with proprietary boards), and now we have to write our own firmware for it in order to be able to use it?

Hi @Bal�zs VARGA​ , you are right, even if the online page declares the full compatibility with the profiMEMS... Did you already try to solder the resistors in the other way? For example, MKIDSOV1 --> LSM6DSO should be STEVAL-MKI196V1, but indeed is not supported... would be better to switch from eMorion to profiMEMS to take advantage of all features of the DSOX (e.g. FSM and MLC)...
