===============System Info==================
ASIC 7620_MP (Port5<->None)
DRAM component: 512 Mbits DDR, width 16
DRAM bus: 16 bit
Flash component: SPI Flash
CPU Speed: 580 MHZ
RAM Size:64 Mbytes

Build Date:Jan 29 2013  Time:15:41:44
============================================

GPIO Init:
        UARTF_SHARE_MODE:GPIO

Please choose the operation:
   1: Load system code to SDRAM via TFTP.
   2: Load system code then write to Flash via TFTP.
   3: Boot system code via Flash (default).
   4: Entr boot command line interface.
   7: Load Boot Loader code then write to Flash via Serial.
   9: Load Boot Loader code then write to Flash via TFTP.
