7.3 Sample Debug session using the TK interface

Before commencing a TK interface debugging session ensure that the USB driver
has been correctly installed. The V850 ZigBeeTM Gateway Development

Platform uses a monitor program for debugging purposes. The communications
between the starter kit and the IAR C-Spy debugger running on the PC is done
via a standard UART / USB connection. The monitor program is automatically
downloaded to the starter kit during connection therefore the user does not need
to take core of the monitor program itself.

Monitor Resources

The following resources are utilised by the monitor program and cannot be used
by the user program when debugging by the TK interface.

Monitor Reset Vector

When a user program is downloaded by using the IAR C-SPY debugger, the reset
vector (address 0x0000) of the user program is replaced by the one of monitor
program. The debugger moves the reset vector of the user program automatically
to address 0x0004. The correction of the relative jump address is also done
automatically by the debugger.

Function

The monitor program is located in the highest FLASH block of the V850ES/SG2
device. Only 2 kB of memory are allocated by the monitor program.

program

Moreover, the monitor reserves 10 bytes of the global stack area by halting the
user program, caused by a forcible break (debugger stop command) or a software
breakpoint.

Clock operation

After releasing a reset, the monitor program sets the operation clock of the CPU
to the maximum speed of 20 MHz. The monitor program switches also to the
maximum CPU speed of 20 MHz when releasing a forcible break (debugger stop
command) or when the user program execution is stopped caused by a software
breakpoint. After the user program execution is restarted (debugger go
command), the monitor restores the previous CPU operation clock setting.

Note

Do not change the frequency of the external oscillator connected to the X1 and
X2 pins.
The baud rate calculation for UARTD0 is based on a 4 MHz input frequency,

otherwise no communication to the V850 ZigBeeTM Gateway Development
Platform board can be established.

Other limitations

The watchdog timer can not be used. Please be sure to set the option bytes of
the V850ES/SG2 device accordingly to allow the watchdog timer disable.

The forcible break (debugger stop command) can not be used when the global
interrupts were disabled by the user program (DI instruction).

Debug sessions

The debug session is done directly by connecting the V850 ZigBeeTM Gateway
Development Platform board to the host PC via the USB cable. The TK interface

of IAR manages the debug session by using the serial interface that is connected
to the USB connecter of the TK-850/SG2+UZ. When using the TK interface serial
communications via UARTD0 is disabled to prevent a clash with the monitor
program. A pre-processor directive has been employed to ensure that the relevant
application code is disabled during a debug session. Please ensure that the
HARDWARE_NOUART pre-processor option is set in [Project] -> [Options] -> [C
\C++ Compiler] -> [Pre-processor] is set and, if necessary, rebuild the application
prior to starting the debug session.

Webpages.R85

Required to ensure correct operation of the TCPIP stack when
No RTOS is employed.

Library containing the web pages, the web pages are also
supplied as source code so that the user can modify the web
pages. Care must be taken to use the same names for the web
pages so that at link time the web page library is not called. Web
pages can generate large code sizes so care must be in the
design to ensure that the 64KB code size limit is not exceeded.

8.3 Embedded functions in Web Pages

All of the embedded functions that are called from the web interface can be found
in the file “httpdfunc.c”; should the user wish to change the functionality of the
web calls please modify the code appropriately.

50

A utility program is provided to convert web pages (see accompanying CNET user
manual) to a large data array; this data is placed in a file called “fsdata.c”. After
conversion this file needs to be modified with the following to ensure the web
pages are located in the correct segment of memory.
