ADXRS450 Request error, PLL failure, Nonvolatile memory fault (NVM)

Dear experts,

i'm new to sensors and things. I'm using the eval board for the sensor. So i did my first SPI implementation today and it seems to work so far.

But no matter what i send i get back "0x1e0200a5" from the sensor.

This means there are the following errors:

- Request error

- PLL failure

- Nonvolatile memory fault (NVM)

I have no idea what the reason could be!

Can anyone give me an advice??

Thank you very much!

Best regards,

Florian
