Spi as slave does not work in FPGA. Zybo Board

Hi, i am trying to build spi as slave in Zybo board. using the example program Slave_intr_example. the mosi pin does not read anything. miso sends data. and clock works fine. the program does not come out of while(Transferprogress==True) and even in debug mode the read buffer will be empty.

Hi @rahulgujaran3,

 

Could you check if you PS SPI controller is configured as slave device appropriately?

Because MISO works at your end and sending data to FLASH.
