Description: PCI Express UART driver patch.

O.S.: Linux 2.4. This patch has been developed on the 2.4.33 Linux  Kernel

To apply the patch:-

1. Paste the patch file into the char forlder in the kernel ( /usr/src/linux2.4.33/drivers/char)

2. To apply the patch, enter the following command:

      patch -p0 < expresso_linux2.4_uart

3. Build the modules using
	
	make modules
	
	make modules_install

4. Reboot the system.    


Note: In the log messages output by the serial module you may see a message like the one below when using a legacy UART:

Redundant entry in serial pci_table.  Please send the output of
kernel: lspci -vv, this message (1415,c140,1415,c140)
kernel: and the manufacturer and name of serial board or modem board
kernel: to serial-pci-info@lists.sourceforge.net.

The driver assumes that any legacy device will have a standard baud_base value,
however ours does indeed have a different baud_base so the above message should
be ignored.
