OpenCore 16550 IP Linux driver

This page is too old and need some updates. Informations on this page are not guaranteed !!

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).

Compilation

 $ make linux-menuconfig

Device Drivers  ---> 
    Armadeus specific drivers  ---> 
        FPGA Drivers   ---> 
            <M>   OpenCore 16550 serial IP driver

 $ make

Usage

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.
