Exploiting commodity FPGAs in the front-end electronics is a standard solution
for readout and trigger electronics for the HL-LHC. It requires the system to be
capable of configuring, debugging and testing the firmware from a remote host.
Furthermore, the control system is also responsible for monitoring and recovery
in case of the SEU errors on the configuration memory of the FPGAs. Realizing
such control capability is a unique challenge for the HL-LHC experiments. We
have developed a control system to achieve such requirements with a new
module exploiting System-on-a-Chip device as the solution for the Level-0
endcap muon trigger system of the LHC-ATLAS experiment. The new module
named JATHub module will provide functionalities of flexible control of the
system: configuration, testing, monitoring, and debugging the FPGAs on the
front-end electronics. In addition, realization of the robust operation scheme for
the possible radiation damage on the JATHub module is another essential item of
development. We have invented a scheme to mitigate SEU errors on the SoC
device and a redundant boot mechanism that will guarantee robust operations
even in case of the radiation damages in the flash memory devices during the
physics data taking with beam collisions. We have fabricated two prototype
boards of the JATHub module. Demonstration study with the proto-modules will
verify the concept of the use of SoC for the management of the front-end
FPGAs in the experimental cavern of the collider experiments for HL-LHC.
