Disable m_rd, m_rr signals for now. Only reading to register works. - Writing ARM -> AXI slave -> mio_in -> mio_tx -> mio_rx -> mio_out -> AXI master -> DRAM works (really basic testing). Signed-off-by: Ola Jeppsson <[email protected]>
Read path from MIO still doesn't work (it times out) s_rd -> mio_in -> mio_tx -> mio_rx -> mio_out -> m_rd ... m_rr -> mio_in -> mio_tx -> mio_rx -> mio_out -> s_rr Signed-off-by: Ola Jeppsson <[email protected]>
