3. Execute setupex.exe
4. Reboot the machine when the setup procedure is complete.
5. Log on as user (or remain as administrator).
To install Wiggler on Windows95:
1. No administrator activities are necessary.
2. Perform steps 2-5 above.
To use the wiggler on either NT or Windows95.
1. Connect the parallel port cable from the PC parallel port to the wiggler.
2. Connect the ribbon cable to the JTAG/COP header. (See caution above regarding Pin1.)
3. Copy the Þle, a:\wiggler\raysÞles\Wiggler.exe to your local directory.
4. Copy the Þles, a:\wiggler\cop_debugger\* (i.e. all the Þles) to your local directory.
5. Using a command prompt window, execute Ocd_cmdt.exe. This is a more thorough test.
6. After using this test, terminate the test.
1.2.1 Using the Wiggler Software for Debug
Launch the Wiggler application. A window will appear with pull-down menus and control buttons to halt or
reset the processor. A button displays the general purpose register (GPR) contents. A button allows the user
to specify an address to Ògo toÓ and begin execution. A help command describes additional functionality.
While this debugger is very basic, it is also very powerful and has several advanced capabilities, including
icache and dcache display and modiÞcation and high-speed code download.
Part 2 Downloading a DINK Upgrade
DINK32 as supplied on the Excimer board is available from MotorolaÕs website in source or s-record
format. While not ofÞcially supported, DINK32 serves as an application note of example PowerPC code. It
is often enhanced with new functionality, support for new microprocessors or reference designs, and bug
Þxes. There may be enhancements or bug Þxes after you have received your Excimer kit. Excimer can be
easily upgraded by downloading the latest DINK32 as s-records into FLASHROM. The following
paragraphs contain detailed instructions for downloading a new DINK32 using SmartCom and
HyperTerminal.
To prepare to download:
1. Obtain the latest DINK32.src code from MotorolaÕs website. (Or download the source Þles and
build your own.)
2. Reset Excimer and strike any key to interrupt the booting of DINK32 while in MDINK.
To download a new DINK32 from MDINK using SmartCom :
1. Put the ßash into a cleared state by typing "fw -e" at the MDINK prompt. This will cause the ßash
to be erased and a new copy of MDINK will be copied from RAM (at 0x00000000) to the ßash
ROM (0xfff00000).
WARNING : In X2 revision Excimer boards, the sector in FLASHROM where
MDINK is stored is eraseable! Typing "fw -e" from the DINK32 prompt instead
of MDINK will erase all of FLASHROM and the board will be inoperable at the
next reset. Should such an unfortunate event occur, MDINK will have to be
reloaded into ßash through the JTAG port (probably in MotorolaÕs Apps Lab).
