Arria 10 boot from MT25QU01G device failure
Hello , I have a development board which consists of two arria 10 devices that retrieve the configuration from a MICRON MT25QU01G device . Although through the usb blaster seems that i can access the memory using JTAG and SFL and successfully write data in the memory , when the two arria devices boot it seems that there is a configuration error. As referred to the datasheet the first arria is configured in active serial configuration scheme by selecting the appropriate MSEL pins while the other in passive serial . I have also tied the nCONFIG, nSTATUS , DCLK , (AS_DATA_0 and AS_DATA_1) and CONF DONE as referred in pin connection and guidelines. Do you know why the FPGAs are not configured properly ? Regards Manolis
Cyclone V SoC custom board preloader boot sdram test issue
Dear Intel FAE and ALL, This is Brian and having issue on maximum 2GB DDR3 boot sanity test. There is a warning like these: "SDRAM: Running EMIF Diagnostic Test ...Iteration 1734:, expect 0x20a69210 from address 0x20a69213, read 0x20a69210 insteadFailed" But w/o the SDRAM test on preloader, the system can boot into distro and passed memtester. Do the preloader have any bug on the memory size of the SDRAM? It do show a 2048M size message. memtester log: ``` brian@brian:~$ sudo memtester 1900M memtester version 4.3.0 (32-bit) Copyright (C) 2001-2012 Charles Cazabon.

STEP model for Cyclone 10 LP Evaluation Kit
Hello all, I downloaded the dev files for the Cyclone 10 LP evaluation kit and can see the layout and sch. all fine. Im wondering if anyone has a STEP file generated from the boards 3D model view? Or has an old enough Allegro install to generate one? Im trying to build an enclosure for the kit itself but need the STEP file for the mCAD side. Thanks, Jg

Agilex 7 I-Series Dev Kit: PIPE Direct for custom PCIe/CXL controller?
Hi Intel Community, I’m studying the R-tile Avalon® Streaming Intel® FPGA IP for PCI Express* User Guide and considering purchase of the Agilex™ 7 FPGA I-Series Development Kit (2× R-Tile, 1× F-Tile). My research goal is to bypass the hardened PCIe/CXL controller and expose the PIPE 5.x SerDes interface into the FPGA fabric, so that I can run a custom soft controller (own LTSSM, EQ, DLLP/TLP, later extend to CXL.io → CXL.mem with 64B FLITs). Before purchasing, I’d like to confirm: PIPE Direct availability Does the I-Series Dev Kit expose R-Tile PIPE Direct to the fabric (via EMIB), enabling a full soft PCIe/CXL controller? Any board-level constraints (e.g., octet-wide Gen5 base mode, per-lane Rate2:0/Powerdown1:0 controls)? Tool/flow support The User Guide notes that Quartus Pro 21.2 had no example/testbench for PIPE Direct. What is the current Quartus Pro version recommended? Are there any reference stubs or app notes for PIPE Direct (Tx/Rx wrapper, reset/clocking examples)? Root Port / Endpoint configs Any guidance on PERST#, equalization sequencing, retrain, refclk selection when not using the hardened controller? CXL hybrid approach If I start with CXL.io only, is it possible to use the hardened PCIe IP just for link/LTSSM while running custom DLL/TLP/CXL layers in soft logic? Or does any custom higher-layer implementation require going fully PIPE Direct? Board I/O Which ports (x16 edge connector, MCIO/SFF-TA-1016) are usable in PIPE Direct mode? Any pinout or kit-specific notes? specifically: if I connect through the edge connector (to a host system), can I still operate the R-Tile in PIPE Direct mode with my soft controller, or is PIPE Direct limited to MCIO breakout only? Validation environment (important) I have access to a CXL-capable host (Sapphire Rapids) but no PCIe/CXL protocol analyzer. Is it realistic to debug link training and equalization in PIPE Direct without an analyzer? If yes, what tools/flows are recommended (ILA debug, Quartus monitors, logging)? Would you recommend starting with two Agilex kits back-to-back instead of host-only, given that I don’t have an analyzer? Are there any Intel or third-party reference setups for early CXL bring-up without protocol analyzers? I’d greatly appreciate any application notes, example projects, TCL scripts, or checklists to help with PIPE Direct bring-up. Thanks in advance!Agilex7i devkit - device not support reconfiguration with factory SDM helper image
Hi, i'm using DK-DEV-AGI027RBES devkit, The board switches are configured as follows, trying to refresh the Agilex7i *.jic file using my design with hps. A while ago i flashed a golden reference *jic via an embedded jtag (J8) and see yocto boot. The same ghrd *.jic reprogramming is blocked by some devices in the JTAG chain. Can you provide steps on how to reprogram *.jic/ghrd *.jic? SW1=ON/Off/Off/Off; SW2=ON/Off/Off/Off; SW3=Off/ON/ON/Off; SW4=Off/Off/ON/Off; SW5=Off/Off/Off/Off; SW8=Off/Off/Off/Off NOTE: I tried flashing the GHRD *.JIC using the devkit embedded USB blaster and I saw the same popup and stopped me from loading the JIC. Also, although *.sof is being programmed, "Error (20064): Error status: Unable to set chip select" always appears. What does it mean? Why am I getting this error? Thanks, Shivaji M
