Just mark the port external and let the VHDL wrapper do its job (or just extract the right pins for single SPI if you want) Export the bitstream and the hardware. Once you have done that, exit the configuration menu and save the configuration changes. Dual and Quad SPI use more data signals to increase bandwidth without increasing the clock frequency. The function ad9361_spi_write is to write a register. config SPI_XLNX_AXI_QUADSPI bool default y depends on SPI && (BOARD_ARTY_A7_ARM_DESIGNSTART_M1 . Re: [LKP] [ovl] 24c944dd64: BUG:kernel_reboot-without-warning_in_boot_stage.

Multi I/O SPI are capable of supporting increased throughput from a single device. The Serial Peripheral Interface (SPI) is a synchronous serial communication interface specification used for short-distance communication, primarily in embedded systems. It is configured for PmodACL2 plugged on JB Pmod connector.
