How to use DE10-nano HPS SPI on LTC connector

[jackhab]

Hi

I'm trying to bring-up Linux application which uses Cyclone V HPS SPI master connected to LTC connector on DE10-nano.

After I couldn't get any live signal from SPI pins I tried the following.

First I've found out that by default the SPI driver is connected to SPI master-0 which does not connected to anything on the board according the DE10-nano schematic.

I recompiled Linux device tree to connect SPI driver to SPI master-1.

I made sure I set the U2 mux  pin IN to zero to select SPI connection.

I still cannot get anything from SPI and I don't get any errors accessing SPI device from my application.

Please, advice.
