Agilex 5E HPS and Linux
Hi. 1. Is there a simple method to run two Linux systems on HPS, i.e.: Linux 1 - 2xA55 and Linux 2 - 2xA76 with different sets of peripherals? 2. Is it possible to use one Ethernet port by these two Linux systems. 3. Is there a simple method for communication between these two Linux systems?
Agilex 3 Baremetal example
We need to be able to run the Agilex 3 as baremetal We tried to re-target this Agilx5 baremetal tutorial: Baremetal Hello World Example for Agilex™ 5 Premium To be used on Altera's Agilex 3 EVB : GitHub - altera-fpga/agilex3c-ed-gsrd: Altera Agilex 3 C-series GSRD · GitHub but this seems to be too great of a task for us - everything there is custom made for the Agilex 5 Please help.Stratix 10 Linux SD card booting
Hi Altera Community, I tried multiple attempts to boot the SD card from Rocketboard.org. https://releases.rocketboards.org/ I downloaded and booted the SD card with the .wic image file. It only has the .itb file by default in the boot partition. Whenever I try to boot, it asks for the U-Boot.img file. And also it says "failed to load "socfpga_stratix10_socdk.dtb" even if the file is there. And then I compiled my simple HPS design and can easily program the FPGA from the Quartus Programmer (rbf and sof file), but whenever I try to overlay it, like say: echo overlay.dtb > /sys/kernel?config?device-tree/overlays/0/path It says "FPGA manager error, timeout," and so on. Does any community member have notes or steps that you made to boot the SD card of the Stratix 10 FPGA? I am following this link: https://www.rocketboards.org/foswiki/Documentation/BuildingBootloaderStratix10HPS First Boot Configuration for Agilex 7
Dear Community, I'm developing a design using Agilex 7 on Quartus Pro 24.2. I'm a bit confused on the parameter settings I need for the HPS (and its EMIF) and my Quartus project settings in order to have HPS-First boot (Called HPS Early Release in former Quartus versions). For that, I'd like to generate .core.rbf and .periph.rbf files. I tried generating the .rbf files in two different ways given below, none succeeded. #1) Having the below pfg command in a text file and sourcing it in my .qsf --convert --hps -o bitstream_compression=on output_files/ProjectName.sof output_files/ProjectName.rbf #2) Using the Programming File Generator tool of Quartus I can generate .sof programming file, but converting that to .rbf fails with the following error when I did either given above. "sof is incomplete. Hps is present but bootloader information is missing". When doing case #2, I even add a bootloader .hex file that I could find on Rocketboards' webpage. Could anyone support me to have an HPS-first boot on Agilex 7 ? Thanks in advance!
HPS ip configuration in platform designer for uart0 enabling in arria 10 soc
I have software tools Quartus prime pro 26.1, soc eds 20.1 and linaro baremetal tool chain. Now i configure the HPs ip for uart0 enabling but i am not sure wether it is correct or not, can you please conform it, and guide if there any changes required and if configuration is fine tell me the next steps to do. Regards Tean D&D, ESSEN
