2Connect the Debugger
This section will explain how the Debugger is connected with iMCU7100EVB. Connect the
Debugger to the DTAG of IMCU7100EVB.
[Fig.2.2] iMCU7100EVB
[Fig.2.2] W7100A / W7100 Debugger
Connect the other DTAG cable between the Debugger and iMCU7100EVB. The red line of
DTAG cable must be connected to line number 1 of iMCU7100A DTAG socket. Also connect the
USB cable between the Debugger and PC. Next, insert the power cable to the IMCU7100EVB,
and push the EVB reset button as figure 2.1. Then, push the debugger reset button of the
Debugger. Confirm the LED5 (RUN LED) after pushing these reset button.

If the Debugger successfully recognizes the W7100A / W7100, the LED5 (RUN LED) will turn
on. But if the LED5 is not turned on, it means that W7100A / W7100 is not recognized. Check
the connecting cable or try to reset the IMCU7100EVB and the Debugger. The LED5 should be
turned on before using the W7100A / W7100 Debugger.

4KEIL Project
Projects that are supported by the W7100A / W7100 debugger are as below.
Keil uVision2 project
Keil uVision3 project
Only hex file (Restricted symbol function)
※The W7100A / W7100 Debugger don’t support the KEIL µVision4 or upper version project. But user
can easily convert the µVision4 to µVision3 project as shown in the figure 4.1 to use the W7100A /
W7100 debugger.
<Fig.4.1> Save Project to µVision3 format
※Caution on W7100A / W7100A Lock function
The W7100A / W7100A has the memory lock function. If the lock was set, user cannot use
the W7100A / W7100 debugger because it cannot read anything from W7100A / W7100A
memory. So user should unlock to use the W7100A / W7100 debugger properly. It is easy to
unlock using the WizISP program. As shown in the figure 4.2, clear the check box and click the
“Lock” button. Whole memory will be erased after the unlocking so user should re-write the
firmware again.
Please refer to the Wiz ISP user manual for more detailed information about WizISP. WizISP
program and user manual are available on the WIZnet website.

W7100A / W7100 Debugger Guide
<Fig.4.2> Unlock the W7100A / W7100A using WizISP program
The W7100A / W7100 debugger cannot recognize multi directory structure of KEIL project
so all project file and source file must be placed in same directory to use W7100A / W7100
debugger. And the ‘make hex file’ option and ‘make symbol’ option should be activated in
the KEIL project. If they are not activated, the W7100A / W7100 debugger cannot find the hex
file to load. Also, an error message could appear even if it finds the hex file.
Since the W7100A / W7100 debugger use slower clock than normal running clock, running
speed under the debugging mode is very slow. So we recommend that don’t use a delay
function or something like that.
First, open the KEIL project.
Click ‘Project’ => ‘Options for Target ‘Target name’ menu.
