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) on JM1-89.

Boot Mode

2 Boot Modes can be selected via B2B Pin Mode. For other options Firmware update is necessary. Trenz Electronic provides currently 2 4 Firmware variants, one for SD and /JTAG, one for JTAG/QSPI, one for SD/QSPI and SD/QSPI/JTAG usage.

lowJTAGBoot from SDBoot from SDJTAG Mode, if NOSEQ* is high otherwise boot from SD
highBoot from FlashJTAGBoot from FlashJTAG Mode, if NOSEQ* is high otherwise boot from Flash

For other UltraScale+ Boot Modes options custom firmware is needed, see also Table 11.1 Boot Modes from Xilinx UG1085.

Note

Set Boot Mode to JTAG, A special FSBL is provided on 2017.4 or newer reference designs to write boot image to QSPI with Xilinx tools (Vivado or SDK) on Boot Mode unequal JTAG .


Note

NOSEQ*: Please check the carrierboard documentation, before using the SD/QSPI/JTAG  firmware variant on TE0820. In the most cases special carrier CPLD firmware is needed.

Power

PGOOD is EN1 and not ER_OUT. There is no additional power management controlled by CPLD.
