SPIM3 instance is not working at 8MHz also

Hi all,

I have customized application which is ported to both Nordic SDK 14.2 and Nordic SDk 15.0. In the app, we use SPI instance to read / write data from the sensor. When I have tested with SPI0/SP1/SPI2 instance at 8MHz , the application works fine with both Nordic SDK 14.2 and Nordic SDK 15.0.

But when I configured SPIM3 instance at 8MHz, the application loops in idle task only. Other tasks stops running.

When I configured SPIM3 instance at 16MHz, SPI CLK results in 16MHz for basic SPI read SDK example

But when I probed SPI CLK of customized application it results either in 16MHz / 625KHz.

Can you please help to resolve the issue?

Thanks in Advance!!

Regards,

Deepa
