    Hi @davec
    I don't see anything wrong with your hardware design or the board files. So I spun up a similar design with port J6, working from the polled_example (Vivado/Vitis 2020.1 and version 4.6 of the xspi drivers). Debugging the modifications showed a problem where XSpi_Transfer was silently failing when checking if a slave was selected in the driver, and finding none. Make sure you are calling XSpi_SetSlaveSelect. See my main.c, below.
    #include "xspi.h" #include "xparameters.h" #include "xil_printf.h" #include "sleep.h" int main() { xil_printf("Hello World!\r\n"); XSpi device; XSpi_Config *pcfg; pcfg = XSpi_LookupConfig(XPAR_AXI_QUAD_SPI_0_DEVICE_ID); XSpi_CfgInitialize(&device, pcfg, pcfg->BaseAddress); XSpi_SetOptions(&device, XSP_MASTER_OPTION); XSpi_Start(&device); XSpi_IntrGlobalDisable(&device); XSpi_SetSlaveSelect(&device, 0b1); u8 bytes [4] = {0xDE,0xAD,0xBE,0xEF}; while (1) { XSpi_Transfer(&device, bytes, NULL, 4); usleep(1); } } Hope this helps,
    Arthur
