Hello,
I am trying to generate pulpino's bitstream without using the processing system loading the programs via SPI SLAVE. I modified the pulpemu folder deleting all the processing system's part and I managed to generate the bitstream but I am getting this warnings:

Then with Vivado I transfer the bitstream to the zedboard and send the code to load the program via SPI SLAVE but I don't get any answer from MISO and it doesn't load the program.
Any help?
