Thanks Jonsmirl, Jen! I revisited the schematics and saw that UART from the CPU is also going directly to a header (besides feeding the serial lines of FT232). So, first I should program the CPU's UART and get output on the header. I will worry about the FT232 later on. Hopefully, it will just work automatically because the same UART is feeding the FT232 also.

If the ft232 is attached to the CPU's console serial port you don't need to do anything to it (make sure it has power and it is wired correctly) and it will work automatically assuming you program the CPU's serial port to work. Just plug the USB end of the cable into a PC and use a terminal emulation program. You need to match up the baud rates. If it is attached the other direction - USB hooked to the CPU, then you will need to use a JTAG until you can get the USB subsystem running in u-boot. Either way getting a JTAG going first will make like easier at the lowest level.
