Flasher ATE—Modular Gang Programmer
Flasher ATE is perfectly suited for high volume mass production environments.
- Gang Programming
- In-System Programmer (ISP)
- Ultra-fast programming
- Control interfaces for ATEs and similar production process handlers
- Switchable target power
- J-Flash and built-in FTP server for an easy setup
- Scalable solution with up to 10 individual channels
- Parallel channels, no demultiplexing required
- Functional isolation of each module
- Target supply voltage may be up to 15V
The modular system uses a communication main board at its heart, that distributes the commands received from an ATE, ICT or a similar automated production handler system to the attached programming modules. Each individual programming module can be set up with individual configurations and firmware image pairs. The Gang Programmer is capable to program multiple devices in parallel, whether these devices are equal or part of a multi-device system, Flasher ATE can handle all production setups.
The Flasher ATE Gang Programmer is an in-circuit-programmer for high volume mass production. To accommodate for the special requirements of high volume production environments, the Gang Programmer can be mounted in 19” racks or be connected directly to an ATE. The interfaces to start and monitor the programming tasks have been designed with the implementer of the production system in mind.
The number of Flasher ATE programming modules per Flasher ATE mainboard can be scaled from 1 to 10 permitting the parallel programming of up to 10 target devices. The ultra-fast flash algorithms used by the Flasher ATE are the same industry leading and proven algorithms also found in SEGGER’s family of J-Link debug probes and Flasher programming devices. Each Flasher includes the licenses to program with all supported MCUs.
The Flasher ATE supports a wide range of CPU cores and an even wider range of different devices from various vendors. On this page, an overview of all supported CPU cores as well as devices for which flash programming is supported, is given.
List of Known Devices
SEGGER Flasher programmers supports a wide range of CPU cores and an even wider range of different devices like SPI-Flash devices. The following lists gives an overview about which devices are supported by SEGGER Flasher.
Note that your device may still be supported even if it is not part of the list. In case of doubt, please feel free to get in touch with SEGGER.
The Flasher ATE can be used for programming flash targets stand-alone. It has to be prepared by using either the J-Flash Software or the Universal Flash Loader Configurator.
Setting up Flasher ATE for the first use
In order to use Flasher ATE for the first time, you need to install the Flasher ATE related software and documentation pack which, among others, includes the J-Flash software. Then, connect the Flasher ATE to the network via ethernet. The Flasher ATE is preconfigured to obtain an IP address via DHCP.
In general, the Flasher ATE should be powered on before connecting it to the target device. That means you should first connect the Flasher ATE to the host system via USB or an external power supply and then connect the Flasher ATE to the target device via JTAG.
Using Flasher with PC Software "J-Flash"
J-Flash is a software running on Windows (Windows 2000 or later) systems and enables you to program your flash EEPROM devices via the JTAG connector on your target system.
J-Flash works with any device/core that is supported by J-Link and supports all common external flashes, as well as the programming of internal flash of ARM microcontrollers.
In order to use J-Flash with the Flasher ATE, the configuration and data files, generated by J-Flash, have to be manually uploaded to each Flasher ATE module via the integrated FTP server.
Device Under Test (DUT) Support
Production environments require more than just creating and programming. Once the production cycle is started, there are all kinds of verifications taking place. The target interfaces of the Flasher ATE Gang Programmer modules include a UART transceiver. This UART transceiver can be managed from the ATE or similar production handler devices via the connection with the Flasher ATE base board. Once it is activated, serial communication via pin 5 and pin 17 is mapped to an IP connection, so the ATE is able to communicate with the freshly programmed device without requiring additional hardware.
LED Status Indicators
Progress and result of an operation is indicated by Flasher ATE Mainboard LEDs:
|Status of LED||Meaning|
|USB GREEN||USB connection established or no USB present.|
|USB RED||Bootloader active.|
|READY/BUSY RED||Programming (>= 1 module).|
|PASS/ERROR GREEN||Programming operation successful (all modules).|
|PASS/ERROR RED||Programming operation failed (>= 1 module).|
Progress and result of an operation is indicated by Flasher ATE Module LED:
|Status of LED||Meaning|
|GREEN, slow blinking (~1 Hz)||Programming.|
|RED||a) The module is in bootloader mode.|
b) The last operation has failed.
Remote Control of the Flasher ATE
The Flasher ATE can be remote controlled by automated test equipment without the need of a connection to a PC. Therefore the Gang Programmer is equipped with additional hardware control functions, which are connected to the SUBD9 male connector, normally used as a RS232 interface to PC. The adjacend diagrams show the internal remote control circuitry of Flasher.
As the remote control circuit only allows limited control of the flash process (trigger all modules at once), the preferred method to control the Flasher ATE is either the RS232 interface or a telnet shell via ethernet. This command line interface allows a detailed control of the flash process of each module as well as putting each module into the UART transceiver mode mentioned above.
|1||START||A positive pulse of any voltage between 5V and 30V with duration of min. 30 ms starts the "Auto" function on all modules (typically erase / program / verify) on falling edge of pulse. The actions to perform can be configured in J-Flash.|
|4||BUSY||As soon as "Auto" is started, BUSY becomes active, which means that transistor is switched OFF.|
|5||GND||Common Signal ground.|
This output reflects result of last action. It is valid after BUSY turned back to passive state. The output transistor is switched ON to reflect OK state.
The last action is considered to be successful, only if all modules report back successful programming.
Software Controlled Operation
If you need full control of the operations of the Flasher ATE you can use the Telnet or RS232 interface for sending commands and receiving qualified result statements.
In contrast to the hardware handshake protocol you can trigger every action of the Flasher ATE separately. Also the commands can be executed individually for every module.
Built-in web server
The built-in web server presents many data of the Flasher ATE for a quick overview of the current operation or for fast trouble shooting.
The web server provides information about:
- the installed firmware version
- the hardware version
- the power consumption
- the IP configuration
- the network load
- current operation and status.
The web server is built with the SEGGER's emWeb software package.
Configuring Flasher ATE via FTP
The Flasher ATE includes an FTP server for easy upload of the configuration files. The Flasher ATE provides a virtual sub folder for very connected flash module. Just upload your configuration and data file, created with the J-Flash tool or Universal Flash Loader Configurator tool, with any FTP client tool into the modules sub folder.
Once you have selected your project file with the "select" command or edited the flasher.ini file in the sub folder of the module, the Flasher ATE is ready for use.
Universal Flash Loader
Besides programming the flash memory via the debug interface (JTAG), there are some devices which are programmed via a device-specific programming interface. These interfaces can be supported by the Universal Flash Loader, a feature for the Flasher ATE, Flasher PRO and the Flasher Portable PLUS.
The Universal Flash Loader supports the serial programming interface of the Renesas RL78 device family, based on a 16 bit microcontroller including over 1000 devices.
Universal Flash Loader Configurator
The Universal Flash Loader Configurator is a software utility to prepare the Flasher for programming. It includes a device database and a comfortable user interface for configuration.
The configuration and data files can be directly downloaded via USB to a connected Flasher ATE, Flasher PRO or Flasher Portable PLUS. The utility is able to save the configuration settings into a project file for later use, so the image file can easily be upgraded.
The Universal Flash Loader Configurator is available for download here.
Besides using the Universal Flash Loader Configurator, it is also possible to manually create or edit a configuration. This might be of interest for very new devices which are not yet known to the configuration utility. The configuration files for the Universal Flash Loader are in the human readable ini file format. For a detailed description of the individual properties please refer to the Flasher ATE User Guide (UM08035).

Since the Flasher ATE is compatible to J-Link it also supports the same target interfaces. Currently the following target debug interfaces are supported:
Additionally to the debug interface, the Universal Flash Loader is capable of arbitrary communication protocols and interfaces.
For more information about the target interfaces please refer to J-Link - Interface description.
There are basically three types of speed settings:
- Fixed JTAG speed
- Automatic JTAG speed
- Adaptive clocking
Fixed JTAG Speed
The target is clocked at a fixed clock speed. The maximum JTAG speed the target can handle depends on the target itself. In general ARM cores without JTAG synchronization logic (such as ARM7-TDMI) can handle JTAG speeds up to the CPU speed, ARM cores with JTAG synchronization logic (such as ARM7-TDMI-S, ARM946E-S, ARM966EJ-S) can handle JTAG speeds up to 1/6 of the CPU speed. JTAG speeds of more than 10 MHz are not recommended.
Automatic JTAG Speed
Selects the maximum JTAG speed handled by the TAP controller.
NOTE: On ARM cores without synchronization logic, this may not work reliably, since the CPU core may be clocked slower than the maximum JTAG speed.
If the target provides the RTCK signal, select the adaptive clocking function to synchronize the clock to the processor clock outside the core. This ensures there are no synchronization problems over the JTAG interface.
NOTE: If you use the adaptive clocking feature, transmission delays, gate delays, and synchronization requirements result in a lower maximum clock frequency than with non-adaptive clocking. Do not use adaptive clocking unless it is required by the hardware design.
The Flasher ATE programming modules provide functional isolation among each other. Do not use with hazardous voltages to avoid risk of electrical shock and fire.
Is it possible to start the individual modules independently from each other?
Is it possible that the modules start the programming process automatically when a board has been inserted (measurement of current consumption or periodic attempt of communication setup) or does this have to be done via the interface?
A: Measurement of target voltage etc. + automatic triggering is on a list for potential improvements. Currently programming can only be triggered by the control interfaces RS232, 3-wire-handshake and TELNET.
How does the access to the individual modules work? How is the programming data transferred? Do I need a Windows DLL?
A: A Windows DLL is not required. The Flasher ATE Programming Modules are set up once - either on the PC or via Ethernet and the corresponding firmware images (one or more) are loaded onto the Flashers. Afterwards, the modules require information on which image should be programmed. Changing data such as serial numbers, MAC addresses etc. can be transferred together with the programming command as "patch data".
