Try this sequence from your program which needs to be updated.

Make bootloader vectors visible 
Write 0x0 to the MEMMAP (0xE01FC040)

Select P0.14 as output. You may want to do a read-modify-write here.
Write 0x4000 to the IODIR (0xE0028008)

Make P0.14 Low
Write 0x4000 to the IOCLR (0xE002800C)

Branch to address 0x0 in ARM mode.

This should invoke the bootloader in ISP mode. Update the code via 
serial ISP and the next reset should execute the new code.

Hope this works for you.
