Functional Description


JTAGEN set carrier board CPLD into the chain for firmware update. In normal mode JTAG is routed directly to Module. Set S3-ENJTAG to OFF to get access to carrier CPLD.

JTAGMODE set module CPLD into the chain for firmware update. In normal mode  JTAG is routed directly to FPGA. Set S3-ENJTAG, S3-M1 and S3-M2 to ON to get access to module CPLD. Attention VADJ is set to 1.8V in this mode.


EN1 is set to logical one after delay.

EN_FMC is set to logical one after delay.

VADJ Selection Table:

ONONVADJ: 1.8V, Attention: Also Module CPLD JTAG access is enabled, see JTAG description.


RESIN (negative Reset) to module, can be set by S2 button.

Boot mode

Boot mode is set to SD-Boot, when SD-Card is detected.


RGPIO Master is a 32Bit Remote GPIO Interface to talk with FPGA over 3 lanes.

Information for users within the European Union in accordance with Directive 2002/96/EC of the European Parliament and of the Council of 27 January 2003 on waste electrical and electronic equipment (WEEE).

Users of electrical and electronic equipment in private households are required not to dispose of waste electrical and electronic equipment as unsorted municipal waste and to collect such waste electrical and electronic equipment separately. By the 13 August 2005, Member States shall have ensured that systems are set up allowing final holders and distributors to return waste electrical and electronic equipment at least free of charge. Member States shall ensure the availability and accessibility of the necessary collection facilities. Separate collection is the precondition to ensure specific treatment and recycling of waste electrical and electronic equipment and is necessary to achieve the chosen level of protection of human health and the environment in the European Union. Consumers have to actively contribute to the success of such collection and the return of waste electrical and electronic equipment. Presence of hazardous substances in electrical and electronic equipment results in potential effects on the environment and human health. The symbol consisting of the crossed-out wheeled bin indicates separate collection for waste electrical and electronic equipment.
