JTAG signals routed directly through the CPLD to FPGA. Access between CPLD and FPGA can be multiplexed via JTAGEN (logical one for CPLD, logical zero for FPGA).
2 Boot Modes can be selected via B2B Pin Mode. For other options Firmware update is necessary.
Trenz Electronic provides currently 2 Firmware variants, one for SD and one for QSPI usage. At the moment JTAG Mode is needed to write QSPI Flash with Xilinx Tools.
Mode | QSPI-Variant | SD-Variant |
---|---|---|
Zero | JTAG | Boot from SD |
On | Boot from Flash | JTAG |
For other UltraScale+ Boot Modes see Table 11.1 Boot Modes from Xilinx UG1085.
PGOOD is EN1 and not ER_OUT. There is no additional power management.
Pin | Description |
