I thought it should be easy enough to connect the MicroBlaze processor with the VHDL module, and make them talk to each other. But, here is the problem...
For the MicroBlaze embedded processor, I've got something like this in the main VHDL module, and I map axi_gpio to a signal:
signal axi_gpio_ch0 : std_logic_vector(31 downto 0);
axi_gpio_0_GPIO_IO_pin => axi_gpio_ch0,
Now, axi_gpio_0_GPIO_IO_pin has to be a buffer (OBUF in my case, as I define it as the input to mBlaze)..? so I have to write something like:
O => O,
I => I
Can I connect OBUF to mBlaze? How can I connect and use axi_gpio_0_GPIO_IO_pin nternaly, without connecting to the FPGA pins.. is this possible?
