            /bypass ............ unlock Spansion bypass mode & disable polling
            /forcealign......... force erase address align with block boundary
            /erasechip.......... erase whole chip, only work with -probeonly
            /clearppb........... erase Spansion PPB,only work with -probeonly
            /showppb ........... show flash sector protection status
                                 only work with -probeonly
            /port:XXX........... customize parallel port(default XXX is 378)
                                 only work in Windows version
            /io2 ............... use alternative Parallel port access method
            /cable:X ........... type: 0-DLC5 paraport
                                       1-Wiggler paraport
                                       2-OpenMoko USB cable(FT2232C/D/L)
                                       3-J-Link ARM/SAM-ICE EMU
            /safemode .......... use parallel cable way operate USB, SLOW!
            /fc:XXX = Manual Flash Chip Selection(disable CFI and ID auto match
                      use 'brjtag /showflashlist' show build-in flash list



 NOTES: *) '-backup:', '-flash:' and '-erase:', the source filename must exist
           as follows: CFE.BIN, NVRAM.BIN, KERNEL.BIN, WHOLEFLASH.BIN or
           CUSTOM.BIN, BSP.BIN, TFE.BIN(64KB or 1x bottom Sector length CFE)

        *) Brjtag default with x16 mode handle Parallel Flash chip. /wx8 switch
           to x8 mode.

        *) Brjtag uses CFI command set to automatically detect flash chip
           parameters. If you have difficulty auto-detecting flash with CFI,
           '/nocfi' convert to original flash detection method. brjtag then use
           detected flash ID query parameters from build-in flash list.
           particularly, you can use '/fc:XX' manually specify flash ID.
           'brjtag /showflashlist' can print build-in flash list

        *) '/forcenoflip' and '/forceflip' can help on some AMD type flash
           detecting sector structure correctly if CFI uses.
           'brjtag -probeonly /verbose' debug flash detection

        *) If you have difficulty with the older bcm47xx chips or when no CFE
           is currently active/operational you may want to try both the
           /noreset and /nobreak command line options together.  Some bcm47xx
           chips *may* always require both these options to function properly.

        *) When using this utility, usually it is best to type the command line
           out, then power up the router, about 0.5 second delay, hit <ENTER>
           quickly to avoid bad CFE code lead to <CPU NOT enter Debug mode>
           or the CPUs watchdog interfering with the EJTAG operations.

        *) /bypass - enables Unlock bypass command for some AMD/Spansion type
           flashes, it also disables polling

        *) /initcpu allow load config code to initialize the CPU. This may help
           BCM6358 prevent from some address non-accessible.

        *) '-probeonly /window:xxxxxxxx /erasechip' allow choose a workable
           sector address to erase whole chip. This may help on a bricked box
           with bad CFE

        *) /forcealign - enable erase sectors if the operation window is not
           aligned with sector boundary. It's risky! but can help erase some
           box NVRAM area whose sector size is larger than NVRAM definition

        *) /ejslow - limit parallel port clock out speed to 500KHz. This wish
           to increase LPT port compatibility for some high clock PC.
           For USB cable this switch can help hit higher clock

 ***************************************************************************
 * Flashing the KERNEL or WHOLEFLASH will take a very long time using JTAG *
 * via this utility.  You are better off flashing the CFE & NVRAM files    *
 * & then using the normal TFTP method to flash the KERNEL via ethernet.   *
