SPI interface with Nios II

Hi,

I try to build the example code and get some errors as below. The errors appear at SPI_MASTER_BASE, SPI_SLAVE_BASE, SPI_SLAVE_IRQ_INTERRUPT_CONTROLLER_ID and SPI_SLAVE_IRQ. Seems like the code needs some real-time interaction in order to run properly.

I found out the example code originally came from https://community.intel.com/t5/FPGA-Wiki/Spi-core/ta-p/735792. May be you can contact the owner via this email [email protected] to know more about the implementing way.

May also search for design examples or codes from these links:

https://gitlab.devtools.intel.com/users/rfrazer/projects

https://rocketboards.org/foswiki

https://fpgacloud.intel.com/devstore/platform/?acds_version=any (Design Store)

Some related design example files had been extracted from first link and attached below just in case you cannot open that link.

Thanks,

Best regards,
Sheng
