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-(XMOD1_A/B/E/G) 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 (XMOD2_A/B/E/G) of this header are routed to the System Controller CPLD U39.

Further JTAG interfaces of the TEBF0808 carrier board are the ARM JTAG 20-pin IDC connector J30 and on the FMC Connector J5. This JTAG interfaces are connected to the System Controller CPLD U17, hence the logical processing and forwarding of the JTAG signals depend on the SC CPLD firmware. The documentation of the SC CPLD U17 contains detailed information on this matter.
