Therefore, the board is equipped with two JTAG/UART headers, which have 'XMOD -FT2232H FTDI JTAG Adapter'-compatible pin-assignment
. So in use with the XMOD-FT2232H adapter-board TE0790 the mounted SoM and the System Controller CPLDs can be programmed via USB interface.
The System Controller CPLDs will be programmed by the XMOD-Header J28 with cascaded JTAG chain as visualized in Figure 8. To program the System Controller CPLDs, the JTAG interface of these devices have to be activated by DIP-switch S4-3.
The 4 GPIO/UART pins of the XMOD-Header J28 are routed to the System Controller CPLD U17.
XMOD-Header J12 is designated to program the Zynq Ultrascale+ MPSoC via USB interface, the 4 GPIO/UART pins of this header are routed to the System Controller CPLD U39.
