WebScanWorks FPGA-based Fast Programming (FFP) builds on a boundary-scan foundation. If you are using boundary scan to program devices, like Flash, then if it is a small amount of data the time to do that is relatively quick. But if the data is large than times can be in the 10’s of minutes to hours. That does not work on a production line.
