The PIN_BU109 (PCIE_PIN_PERST_N_I in GTS PCIe IP) is left floating. I do not understand clearly what you mean by "You may check the remaining PERST pins on these two banks." Please see attached the schematic of the Bank 5A and 5B : Please let me know what I have to check exactly. Thanks. Serge PCIe reset stuck on Arrow Eagle board I am doing an NVME Host IP to drive SSD NVME. I'm using an Arrow Agilex-5 EAGLE Board with Device A5ED065BB32AE4SR0 with Q25.1.1 I have connected on the PCIe Edge the AB19-M2PCI board on which I have connected an SSD. The GTS AXI Streaming Intel FPGA IP for PCI Express stay always in reset. The signal 'p0_pin_perst_n' of the GTS AXI Streaming Intel FPGA IP stay at 0. I have connected the following pins : - input p0_pin_perst_n_i_reset_n assigned to PIN_CF132 which is PCIE_RTSb - input p0_pin_perst_n_1_i_reset_n I've tried to assign to many different pins which were reasonable to connect, but was getting error during the Fitting stage. The only pin assignment which passing compilation is suggested by tool: PIN_BU109 which is according to schematics CX_SMB_SDA set_location_assignment PIN_CF132 -to PCIE_PIN_PERST_N set_location_assignment PIN_BU109 -to PCIE_PIN_PERST_N_I # set_instance_assignment -name IO_STANDARD "3.3V LVCMOS" -to PCIE_PIN_PERST_N -entity top_nvme set_instance_assignment -name WEAK_PULL_DOWN_RESISTOR ON -to PCIE_PIN_PERST_N -entity top_nvme # set_instance_assignment -name IO_STANDARD "3.3V LVCMOS" -to PCIE_PIN_PERST_N_I -entity top_nvme set_instance_assignment -name WEAK_PULL_DOWN_RESISTOR ON -to PCIE_PIN_PERST_N_I -entity top_nvme Do you have an idea why the GTS AXI Streaming Intel FPGA IP stay at 0 ? Re: AGILEX 5E : GTS AXI IP PCI Express : What is the mapping of the PCIe Header on _tuser_hdr[255:0] Thank you Wincent. Serge Re: AGILEX 5E : GTS AXI IP PCI Express : What is the mapping of the PCIe Header on _tuser_hdr[255:0] Hello Wincent, Thank you for your answer but I meant the detail mapping as the following picture for Tdata : Do you have the same for the _tuser_hdr[255:0] signals ? Thank you. Serge AGILEX 5E : GTS AXI IP PCI Express : What is the mapping of the PCIe Header on _tuser_hdr[255:0] Hello, In AGILEX 5E : GTS AXI Streaming IP for PCI Express user guide : ug-813754-855610.pdf What is the mapping of the PCIe Header on "_tuser_hdr[255:0]" signal when the PCIe0/1 AXI-ST Sideband Header parameter is enabled. We have the mapping for the Tdata signal but not for the _tuser_hdr[255:0] signal. Is it the same mapping ? Thank you. Serge SolvedRe: Agilex 5 GTS Reset Sequencer Intel FPGA IP : what value to set to i_refclk_bus_out with a PCIe IP ? Hello Wincent, Yes it takes longuer than expected on AGILEX 7, so please close this case and I will come back to you when ready on AGILEX 5. Thank you for your help. Serge Re: Agilex 5 GTS Reset Sequencer Intel FPGA IP : what value to set to i_refclk_bus_out with a PCIe IP ? Hello Wincent, Not for the moment, I am still busy with AGILEX 7-I-R-Tile. I will come back to you afterwards. Thnak you. Serge Re: Agilex 5 GTS Reset Sequencer Intel FPGA IP : what value to set to i_refclk_bus_out with a PCIe IP ? Hello Wincent, So, I sent you my design which is done without qsys, only with VHDL files. I did not sent you the design from https://github.com/altera-fpga/agilex5-ed-pcie-rp/releases/tag/25.1-1 project and on which I removed nearly everything becasue this is non sens. So, the idea is the Altera IP expert analyze my design to see what is missing to avoid the bus error. >> is the design work well ONLY with GTS Reset sequence and the PCIe IP ? >> I think you might need to connect with the rest right ? I do not understand this questions. The goal is to provide me an instanciation of a GTS AXI Streaming PCIe IP on AGILEX 5 I can compile without errors. Yes we can organize a Team call, I am based in Paris, France. I am available Thursday an Friday morning of this week. Please send me a link. Thanks for help.

Serge Re: AGILEX 5 Reset for GTS AXI Streaming IP documentation Well, the 4.3 section is quite short an do not describe at all the "Reset for GTS AXI Streaming IP" and its ports. May be later one documentation will appear. Thanks. Serge
