We are using SPI-0 as master (uses SS-0) and SPI-1 as slave (uses SS-0) on our custom Zynq-7020 board. We have verified SPI-0 interface but SPI-1 does not seem to receive anything. Even when we set internal SPI-to-SPI loopback mode (through SLCR MIO-LOOPBACK reg.) SPI-1 receives nothing. We can reach registers of SPI-1 correctly so we assume SPI-1 is clocked properly. But after transmission completed, there is no change in status register of SPI-1 and Rx FIFO reads return all 0x00s. Any similar experience or suggestions for using PS SPI in slave mode or using both PS SPI peripherals?

SPI-0 uses MIO[40...45], SPI-1 uses MIO[46...51], MDIO uses MIO[52...53] and Eth-0 uses MIO[16...27], so yes, both SPIs and MDIO can be configured without any conflict.

Hello, I am having the same problem. I managed to run loopback mode in ZedBoard but on a custom board slave spi is not responding. İs there any progress ?
