Flasher PRO XL
Flasher PRO XL is the extra-large memory version of SEGGER’s universal flash programmer Flasher PRO, including all the same features, plus:
- 2 GB of integrated flash memory
- the option of further memory expansion
Flasher PRO XL—The Universal Flash Programmer for Huge Images
The Flasher PRO XL is the extra-large memory version of SEGGER’s Flasher PRO. With all the same features of the Flasher PRO, the Flasher PRO XL expands upon the original’s 128 MB memory with 2 gigabytes—16 times as much internal flash memory. This memory can be used to store a variety of large program images. With its huge memory capacity, Flasher PRO XL can also program target systems running large footprint OSes such as Android, Linux, Windows CE.
Flasher PRO XL can be used in stand-alone or PC-based mode. It connects via USB, Ethernet or an RS232 interface. Like the Flasher PRO, the Flasher PRO XL supports a wide range of CPU cores and an even wider range of different devices from various vendors. Software and firmware updates are included. Similarly, use on all target devices currently supported, and on any that will be added, is also included.
No additional licenses required.
No hidden costs.
No future costs.
Advantages
Extra-Large Memory
The Flasher PRO XL can manage devices with more than 128 MB of memory to be stored or programmed beyond code, even in stand-alone mode. It comes with the option of memory expansion. If there's more than 2 GB needed, it can easily be adapted to the customers' needs by using an industrial-grade microSD card to cover even the largest of systems.
Universal Target Support
The Flasher PRO and Flasher PRO XL support the programming of thousands of different microcontrollers’ on-chip memories via their debug or dedicated programming interfaces. They can be programmed indirectly, via the microcontroller or SoC, or directly. They support a variety of interfaces.
High-Speed Programming
Flasher programmers reduce programming time to the programmed hardware’s theoretical minimum. Turbo mode programming helps achieve high performance which utilizes parallel operation of programming and transmission – all while using only the available bandwidth.
Use Cases
Programming Rich User Interfaces Integrated into Complex Systems
The Flasher PRO XL can program large data sets. These could be built-in color displays with high resolutions, touch screens integrated into complex in-vehicle infotainment systems, or medical equipment like ultrasonic devices and respirators. Graphics are not generated in the devices themselves but stored as huge image files. If they need to be changed (like during a firmware or design update), fast programming is important to avoid failure.
