i.MX8M Mini processor - Unused MIPI-CSI lanes

[M8]

Hi,

I have unused MIPI-CSI lanes in i.MX 8M Mini processor. What will be the impact if I have left those pins (Pins A14-A18, B14-B18) floating? 

Is it mandatory to connect them to Ground?

Thanks

We have some boards where they are left floating. Can you pls share what will be the impact in that case?

It is hard to say what is the impact of it. We didn't test this kind of case before. Normally, we recommend our customers to follow the hardware development guide.

Yes, for unused MIPI_CSI_Dx_P/N pins, should all tie to ground.
