I having some issues with generating SPI master core in qsys.
I opened a clean design (with no core in it), and added the SPI core to it and exported all of its signals.
When I tries to generate the design, its gives an error about a missing file - spi_0 What am i doing wrong?
I figured it out, it was quit weird. Turns out Qsys requires a "clock source" IP core in order to generate the SPI core.
