Can i change clock speed/spi size? I did try with interface spix4 & got the following message
ERROR: [Writecfgmem 68-20] SPI_BUSWIDTH property is set to "1" on bitfile C:/Users/wesleyt/Documents/Project/FPC02/chip_top.bit. This property has to be set to "4" to generate a configuration memory file for the SPIX4 interface. Please ensure that a valid value has been set for the property BITSTREAM.Config.SPI_buswidth and rerun this command.
The generation of the bit file is out of my hands unfortunately.
