Hello,
I am currently exploring on how to add a AXI MMIO port to connect a device. Can anyone help me in this?
And is it possible to change the AXI address from 31 bits to 64bits ?

Thanks and Regards,

Hi,

If you want multiple AXI-based MMIO devices, the easiest way is to duplicate all the classes related to AXI_MMIO configuration. If you need a detailed example, feel free to let me know.
