up_control.dll library

The up_control.dll enables user to control the UP software

using functions contained in the library. It contains basic

programming functions.

From the view of the user the UP software is running

invisibly.

There is more information concerning the library available

in a separate

document.

FORTE.DLL Library

Function s implemented in forte.dll enable setting and

reading of logical levels on single pins of FORTE

programmer. This way it is possible to make various

communication protocols.

Except for functions which enable controlling of the single

pins, the library contains also functions prepared for

communication via SPI, I

C and 1-Wire buses, functions

for supply and programming voltage controlling and

supply voltage and GO button reading.

The functions implemented in the forte.dll library are

described in detail in a separate document devoted to

this library.

JTAG PLAYER

JTAG PLAYER is a utility designed for programming

devices with the JTAG interface by means of PRESTO or

FORTE programmers.

This utility is not part of the UP software installation pack

but it can be downloaded separately from

https://

www.asix.tech/prg_jtag-svf-player_cz.html

JTAG PLAYER is localized only in English.

8.1

JTAG Device

Programming

Having started JTAG PLAYER, select your programmer in

Options ➙ Select Programmer.

If you cannot see your connected programmer in the

dialog window, check if the green ON-LINE LED on the

programmer is on. If so, make sure thatanother software

is not communicating with the programmer.

Program the device by choosing File ➙ Open&Process.

The file to be programmed must be in SVF/XSVF format.

For more information on the file format see

SVF File or

XSVF File.

If an error occurs during the programming process, check

the connection between the programmer and the

application. In addition, check the presence of a feeding

voltage.

Important warning

A power supply voltage from an external source must be

present during programming that utilizes the JTAG

interface. The programmer does not feed the application

in this case.

8.1.1 SVF File

SVF (Serial Vector Format) is a file used for describing

high-level operations on the IEEE1149.1 bus.

Serial Vector Format (.svf) is the recommended file

format for all the testing and programming except

for Xilinx CPLD XC9500. The Xilinx Serial Vector

Format (.xsvf) is recommended for Xilinx CPLD XC9500.

Examples of How to Create SVF

Files

This chapter presents methods of creating an SVF file for

different types of device.

Atmel AVR (e.g. ATmega128)

Programming

Generate an SVF file using the avrsvf.exe program

available at the ATMEL website in the “Tools & Software

of AVR 8-bit RISC MCUs” section.

Example:

avrsvf -datmega128 -s -e -ifmyfile.hex -pf -vf -

ovmyfile.svf -mp

This example shows how to create an SVF file from the

myfile.hex file. The final SVF file is then used by

jtagplay.exe for erasing, programming and verification.

Run avrsvf -h for more information.

The device must be in the reset state during

programming.
