Notes :

  • For carrier or stand-alone boards use subsection for every connector type (add designator Designator on description, not on the subsection title), for example:
    • SD
    • USB
    • ETH
    • FMC
    • ...
  • For modules which needs carrier use only classes and refer to B2B connector if more than one is used, for example
    • JTAG
    • UART
    • I2C
    • MGT
    • ...

JTAG/ GPIO to Module CPLD

JTAG access to the System Controller CPLD is provided through B2B connector J3. JTAG access to CPLD is provided by TE0790 XMOD Adapter on Pin Header J8.

Pin 'JTAGENB' must be set high, using DIP Switch S1-A in order to program the System Controller CPLD via JTAG interaface.
