To rule out some simple stuff up front:
Are you doing any configuration via JTAG that you aren't doing without (eg.
peripheral bus setup, GPIO configuration, etc.)?
Can you see data in the RX FIFOs without JTAG attached?
Do interrupts arrive for the two additional serial ports when data comes into
the RX FIFO?
