Hi, I'm new here so let me know if I do anything wrong.
I'm trying to use a Minnowboard Turbot for controlling a Bluetooth module via UART.  We are trying to use the PCI UART1 but we aren't seeing the TX pins send any data.
I've tried various settings in the BIOS to enable the serial port.  Regardless, on startup Linux always just shows ttyS0 as an enabled serial port.  Using minicom or just echoing to /dev/ttyS0 does not TX any data (we have an oscope on pin 6).
lspci shows an HSUART controller with no I/O memory and so far I haven't found a way to enable this device, if that is what I should do.
Can someone point me in the right direction, or drag me back to the path?
Thanks!
