This is the user documentation for owners of a SEGGER Flasher Hub-12.

This article is work in progress.


How Flasher Hub-12 works

Flasher Hub-12 makes ultra-fast high speed parallel programming ("gang programming") with up to 12 channels possible. Flasher Hub-12 is connected to one or more modules (Flasher Compact). Each module is connected to a target chip. Using one of the Flasher Hub-12's host interfaces, flash programming operations can be triggered and responses from the Flasher Hub-12 can be read and evaluated. This makes the Flasher Hub-12 a perfect fit for small-scale as well as large-scale production environments.
