5.1. Configure FPGA and access HPS Debug Access Port by JTAG
- JTAG access does not rely on SW1 settings and system image.
- Plug the USB cable to CN1 or Intel® FPGA Download Cable to J19.
- Open Intel® Quartus® Prime Programmer, system console to configuration Intel Agilex® 7 FPGA SDM, system Intel® MAX® 10 and PCIe JTAG nodes.
- Open Arm* Development Studio 5* (DS-5*) Intel SoC FPGA Edition to connect to and communicate with the HPS Debug Access Port (DAP) through the same JTAG interface.
Note: By default, HPS and FPGA SDM JTAG nodes are chained together internally. SW3.1 bypasses or enables both nodes at the same time. OOBE’s Mictor 38-pin header cannot access HPS DAP function.
If attestation and/or Black Key Provisioning (BKP) is enabled on the Intel Agilex® 7 device, you must use the updated SDM firmware and TCK guidelines (JTAG clock).
- You must update to the SDM firmware delivered with the Intel® Quartus® Prime Pro Edition version 21.3 and beyond.
- For the TCK pin, you must either leave the TCK pin unconnected, or connect the TCK pin to the VCCIO_SDM supply using a 10-kΩ pull-up resistor.
Note: The existing guidance in the Intel Agilex® 7 Device Family Pin Connection Guidelines to connect TCK to a 1-kΩ pull-down resistor is included for noise suppression. The change in guidance to a 10-kΩ pull-up resistor is not expected to affect the device functionally.For more information about connecting the TCK pin, refer to the Intel Agilex® 7 Device Family Pin Connection Guidelines.
