Agilex 7 I-Series "aocl diagnose acl0" error following OFS
Hello, I've been working through the Open FPGA Stack (OFS) guides to set up my Agilex 7 I-Series development kit for use with oneAPI. I've worked through prior SystemVerilog issues encountered by switching the generated FPGA Interface Manager (FIM) from a 1x16 PCIe configuration to a 2x8 configuration (although 1x16 would be more preferred). I am now on the final step of wrapping the FIM into a BSP and validating it for use with oneAPI by running the "aocl diagnose acl0" command. I should note that performing just "aocl diagnose" works fine. When I add "acl0" and execute, however, I find that all attempts to communicate between the host and FPGA via DMA fail (although we do see a single VTP L2 4KB hit). The exact output from the diagnose command is in the text file attached. I have tried using both a minimal FIM generated via command provided in the OFS guides, as well as pre-builts from the Github page. Why might this error be occurring, and how can I fix it? Any help is greatly appreciated, thank you! James
LTC Connector DE10-Standard FPGA
I am trying to access the I2C bus on the LTC connector on the DE10 Standard FPGA board. I have enabled the i2c controllers on the HPS. How do I now gain access to the i2c2 pins that are connected to the ltc connector from the HPS? I was able to communicate to the g-sensor that shares the same bus with the ltc connector, but I need to access the LTC connector to communicate with a separate board. I see that there is a TS3A5018 switch. Am I required to set the HPS_LTC_GPIO to low to switch communication from spi to i2c? Kindly help.
Regarding MIPI CSI 2 TX
Hi, In my Project, I have to generate test pattern data and send it to MIPI CSI 2 via AXI stream, and MIPI CSI 2 will send the pixel data to link_0 of MIPI DPHY IP , but when i try to simulate the design(includes MIPI CSI 2 and MIPI DHPY IP interconnected), mipi_dphy_0/LINK0_CK_Stopstate is constantly high, I guess this signal is supposed to go low after T INT time, and also ready Singal from axi_stream is asserted low after being high for three clock cycles, i didn't understand why. Any help is appreciated.NIOS V Sysnthesis Fails with Quartus 25.1 Lite

Quartus Assembler-only run after updating ROM .mif — should .sof/.pof checksum change?
Hello, I have a question about Quartus output files and checksums when only the Assembler is re-run. 1) Run a full compile once (Analysis & Synthesis + Fitter/Place & Route). 2) Modify a *.mif file that is used as the initialization file for a Quartus IP: “ROM: 1-PORT”. 3) Without re-running Analysis & Synthesis or the Fitter, run: 4) Processing → Start → Start Assembler 5) to regenerate the .sof and .pof files. A customer asked whether the checksum of the generated .sof/.pof should remain unchanged because the logic is not re-synthesized and the design is not re-fitted. However, in my repeated tests, the checksum of the .sof/.pof changes every time the contents of the .mif file change. Could you please confirm whether this behavior is expected? In other words, does the Assembler incorporate the updated memory initialization data into the programming files (thus changing the file contents/checksum), even though A&S and Fitter are not re-run? Any clarification or recommended flow for updating ROM init contents would be appreciated. Best regards,Behavior of 10 GX Avalon-MM Interface for PCI Express* IP Core when byteenable=16'h0000
Hi, we are using an Arria® 10 and Cyclone® 10 GX Avalon® Memory-Mapped (Avalon-MM) Interface for PCI Express* IP Core. During our tests we noticed some illegal PCIe packages generated presumable due to a wrong data length. We could tackle down the problem to the following basic setup: avalon_mm_master => 128 bit bus => PCIe-Core When we send the following sequence (two words), we get an illegal/unexpected PCIe transfers/behavior: burstcount = 2, address = address_a, data = some_data, byteenable=16'h0000 burstcount = 1, address = address_a+16, data=some_data, byteenable=16'hFFFF When we only send the second word everything works fine. This sequence originally comes from a qsys autogenerated 256=>128 width change in the interconnect somewhere upstream in our project. My question is: Do we miss something here? Does the IP-Core not allow for a first word to be completely disabled? If so, is there any (automatic) way to tell qsys / the interconnect to discard a leading all_bytes_disabled word? 5.3. 64- or 128-Bit Bursting TX Avalon-MM Slave Signals Best regards, Michael
Regarding Quartus Prime License Activation for the Agilex 5 Evaluation Kit
Does the Agilex 5 Premium Development Kit include a one‑year paid Quartus Prime license? The product brief states that it is included, but I would like to confirm. https://docs.altera.com/v/u/docs/815177/agilextm-5-fpga-e-series-065b-premium-fpga-development-kit-product-brief If the license is included: ・Is the same one‑year license also provided with the Modular Development Kit? ・Does the bundled license also include the IP Base Suite, as with a standard paid Quartus Prime license?
