OpenCore 16550 IP Linux driver
Thanks to the OpenCore 16550 serial IP integration in POD, you can add at least 4 complete RS232 ports to your Armadeus board (depending on the FPGA capacity).
$ make linux-menuconfig
Device Drivers ---> Armadeus specific drivers ---> FPGA Drivers ---> <M> OpenCore 16550 serial IP driver
Assuming you have previously loaded your FPGA with the corresponding IP:
# modprobe 8250 # modprobe 16550_ocore
Now you should have as much /dev/ttySN as 16650 cores you put in your bitfile.
