Hello Sir,
We need to change IO address to avoid conflict of IO address, 0x3f8 with other COM port.
Can IO address of legacy UART of Bay Trail be changed to 0x2f8?
Thanks,
Riven

Hi Riven,
Legacy UART for Bay Trail SoC is on PCU Fixed IO Address Ranges which has the IO address of 3F8h-3FFh.
The device is not included on the Movable IO Ranges Decoded by PCI Device on the IO Fabric.
In this case it would not be possible to change the IO address to 0x2f8.
Here is the public datasheet for reference.
