The Flasher ARM is used to program the non-volatile memories of Arm-based microcontrollers and Systems-on-a-Chip (SoCs) as well as external flashes like (Q)SPI flashes that are directly connected to the microcontroller. It can be used in stand-alone or PC-based mode and connects via USB, Ethernet or an RS232 interface. Like the Flasher PRO, it has a 20-pin connector, which is compatible with the standard 20-pin JTAG connector defined by Arm. Various adapters are available.
As a multi-platform solution, Flasher ARM comes with the setup and control software for Linux, macOS and Windows. Software and firmware updates are included. Similarly, use on all target devices currently supported, and on any that will be added, is also included.
- Has 128 MB internal memory
- Supports internal & external flash devices
- Built-in web & FTP server for easy setup
- Includes Flasher software package
- No license required. No hidden costs. No future costs.
- Future proof: Software, firmware updates, and new flash loaders are free of charge.
SEGGER Flashers support a wide range of CPU cores and an even wider range of different devices, such as SPI flash devices.
This includes support for tens of thousands of devices in hundreds of device families with billions of devices programmed.
Universal target support
Flasher ARM has a very flexible target and programming interface.
Based on an FPGA with an integrated CPU core, it has multiple dedicated soft cores controlling the target interface, and a virtual processor running the flash loader.
This concept makes it possible to adapt to almost any system for ISP programming purposes. Dedicated flash loaders, which can be easily downloaded to the programmer, make it possible to program almost any device. This flexibility allows using the debug or dedicated programming interfaces of microcontrollers to program the on-chip memories as well as the programming of the off-chip parallel or (Q)SPI flashes. (Q)SPI can also be programmed directly.
Future software and firmware updates as well as any new flash loaders for target devices that will be added, are also free of charge.
- No licensing costs, even for newly supported devices.
- No hidden costs.
- No future costs.

Flexible control and monitoring
The Flasher ARM is easy to set up and operate using SEGGER software tools. It can be operated in either stand-alone or PC-based programming mode. In stand-alone mode it can be operated via remote control (USB, UART, Ethernet) or by the push of a button or TTL triggers.
Serial number assignment
Many modern devices require some pieces of unique information. Flasher ARM allows the programming of data that differs amongst other otherwise identical units. Typical examples are things like serial numbers, ethernet hardware addresses (MAC), and digital signatures, and license keys that enable/disable product features. All these options can be adapted from device to device by applying patch data to the original firmware.
Built-in web server
The Flasher ARM offers options to check status information remotely and to configure the device.
The Flasher ARM comes with SEGGER’s built-in web server. It is designed to present important device and current operation data for a quick overview and, additionally, to check the status of the programmer, providing information about:
- Installed firmware version
- Hardware version
- Power consumption
- IP configuration
- Network load
- Current operation and status
- Programming interface in use
This may be important for fast troubleshooting through code verification, for instance, as it is when executing a cyclic redundancy check (CRC) that helps to detect errors during data transmission or storage.
If needed, the built-in web server’s programmer settings can be checked and adjusted. These could, for example, be parameters like:
- Subnet mask
Built-in FTP server
The Flasher ARM also includes the emFTP server to upload firmware and configuration or download log files.
Remote file update
Using the emFTP server enables easy upload of configuration files and firmware images. By connecting to the emFTP server using an FTP client of choice, files can be transferred between client and Flasher.
Having access to the Flasher configuration via FTP enables configuration of multiple Flashers from a central production control server. This interface can be also used to make the production line part of a CI/CD system to push stable releases into the current production.
Analyzing the reliability of the production line is an important task, when it comes to increasing the production frequency. This purpose is supported by the built-in FTP server, which lets users check the history of past programming cycles via log file download. Each entry provides the following information:
- Result (success/failure)
- Serial number (if programmed)
For failed programming cycles, the log file provides additional information for quick troubleshooting (e.g. failed to open Flasher config file).
The Flasher PRO is SEGGER’s full-featured, in-circuit flash programmer for microcontrollers and SoCs as well as (Q)SPI flashes. It is designed from the ground up to be a fast and universal flash programmer.
