Running JTAG Player
from Command Line
SVF & XSVF JTAG Player can be run from the command
line for more comfort especially during debugging. The
following parameters apply:
jtagplay.exe [-p] [-f filename] [-i inifile] [-
c] [-cc] [-s serial]
-p automatically executes the file specified in
the -f filename parameter
-f filename specifies SVF / XSVF file to be executed
-i inifile ini file containing settings
-c closes the program if the file has been
executed without errors
-cc closes the program even if the file has been
executed with error(s)
-s serial uses PRESTO or FORTE programmer of the
specified serial number, when instead of
the serial number there is the "-" (dash)
sign, it will use any connected programmer
regardless of its serial number
-forte uses FORTE, not PRESTO
Return Codes
The jtagplay.exe program returns the following return
codes:
0 execution of the last file had no errors
1 an error occurred during execution of the
last file
2 execution of the last file could not be
started

MultiUP
MultiUP is utility usable for programming with up to 4
ASIX programmers at once. MultiUP uses program UP.
The utility is installed together with the UP program.
MultiUP can simply, using one button, run programming
of selected task, which is deffined with the UP program
project and other settings.
To increase speed the utility loads the programming data
only once, it is suitable for using in production.
9.1
Programming settings
In the "Options/Programming settings" it is possible to
select programmers to be used, UP program project to be
programmed, whether they will program the common
way or using the differential programming and the
memories to be programmed.
To improve clarity it is possible to select a name for each
of the programmers.
Each of the programmers can program a different project
or all of them can be the same project.
All of the programmers do not have to be of the same
type (PRESTO, FORTE), but the selected project have to
use the same type of the programmer.
In the Options it is also possible to select Keyboard
shortcuts for running work of the praticular programmers
and to set the console saving during the program closing.
The parameters configured in the Options can be used
once or they can be saved to MPPR file for other using.
9.2
Programming
For programming of predefined tasks it is advisable to
open MultiUP project file in menu "File/Open MPPR file".
The project can be crated in the "Options" menu.
Afterwards the particular programmings can be run
separately using the "Run" button on the appropriate
programmer panel or all the active programmings can be
run at once using the "Run all" button, eventually the
associated keyboard shortcuts can be used.
9.3
CommandLine
It is possible to provide the MPPR project path on the
commandline, it will be loaded on the utility start.
Example:
multiup.exe C:\data\project.mppr

TROUBLE-SHOOTING
This chapter describes how to proceed if experiencing
difficulties with device programming. It also describes
testing utilities for PRESTO and FORTE programmers
designed to check if the programmer is in good condition
or damaged. Please go through all the tips and tricks
before you send your programmer to a service shop.
The testing utilities are not part of the UP software
installation, but they can be downloaded separately from
https://www.asix.tech/prg_testers_en.html.

Tips and Tricks
Should you experience difficulties with programming, we
recommend checking the following points:
• Check the microcontroller and programmer
connections according to the description in Connecting
to Application. Even though it may seem trivial, it is
recommended to check the connection twice and to
assume the second time that the link does not always
lead where you want it to or it leads to more than one
point.
• If a crystal or other auxiliary devices are used for
programming, (typically pull-down or pull-up resistors),
check if their values and connections are correct.
• It is advisable (and often necessary) to have blocking
capacitors at the power supply of the device to be
programmed.
• If the device to be programmed has more than one
power-supplying pin, all of them must be really fed. It
is often recommended to check their voltage with a
voltmeter.
• Use of the latest version of UP is recommended. If you
are still using an older version, an update is
recommended.
• Are you programming a new device or has it been
previously programmed? If so, the problems may be
caused by unsuitably set fuses in the device.
• The length of the ICSP cable should not exceed 15cm.
• Make sure that there is no additional capacity present
at the programming (data) pins. Consider if circuits on
the programming pins could cause too large a load for
programming.
• It is important that the crystal or the communication
speed settings reflect the reality in devices that need
that settings.
• Some devices may be programmed using several
different methods. Programming problems may be
caused by selecting a different programming interface
or a different programming mode than the ones that
the application is prepared for.
If none of the above tips help to eliminate the problem
and if it absolutely sure that the device to be
programmed is not faulty, the fault may lie in the
programmer.
To easily find out whether the programmer is in order or
not, you can use the testing utilities described in the
following chapters.
10.2
PRESTO Tester
he PRESTO Tester utility easily tests the “health
state” (usability) of the PRESTO programmer right at the
customer's site.
In order to run it successfully, only one PRESTO
programmer may be connected to the control PC and its
drivers must be correctly installed. This is confirmed by
the green LED being on.
