Abstract
This paper presents the design and implementation of a system for remote reconfiguration and reprogramming of the FPGAs in the off-detector electronics of the Electromagnetic Calorimeter (ECAL) of the CMS detector.The main benefits of this system are: the reduced time needed to reprogram the FPGAs firmware; the increased mechanical safety avoiding hardware manipulations when the update is performed; and the possibility of performing the firmware update in several boards in parallel.The access to the ECAL off-detector boards makes use of the Module Test and Maintenance (MTM) bus existing on the VME64X crates. The JTAG Distribution Board (JDB) board is the central unit of this system. The functionality and implementation of the system, as well as the corresponding software tools, are described in this paper.
