Hi there, I am using the DE0 Nano Soc (cyclone V), I am abble to write data from HPS to FPGA using the avalon mm slave, but when I want to write from the fpga to HPS using the avalon mm slave, the HPS crash, indeed the linux terminal is blocked, I can write anithing on it.
I am using this simple code for the moment.
if rising_edge(clock) then
if read = '1' then
readdata <= "10111010001100110011001100110000";
the same code but with a write condition works well.
