Unable to access HPS periphery on Agilex chip

Hi there, We are using the Intel Agilex dev kit v3. We've instantiated the HPS together with some memory mapped IO components (Have a look at the attached screenshot of QSYS) and try to Boot linux ...

Hi leondietrich,


It may have something to do with your boot and configuration sources.

This document might help https://www.intel.cn/content/dam/altera-www/global/zh_CN/pdfs/literature/hb/cyclone-v/cv_5400a.pdf

Refer to the first few pages of that documents to identify the method of your system trying to boot with. Then determine your boot and configurations sources based on those different method mentioned.

Which documents that you refer from rocketboards for your booting process?


Thanks.

Regards,

Aik Eu

    Hi,

    Refer to the first few pages of that documents to identify the method of your system trying to boot with. Then determine your boot and configurations sources based on those different method mentioned.

    We are using the FPGA first boot approach. We use the programming file generator to mix our bitstream with the FSBL hex file obtained by running bitbake and program the FPGA using the new sof file. The FSBL then loads the SSBL from an attached SD-Card (which works fine) and then either boots the referenced dummy test payload (which also woks fine) or the linux image (which does not work).

    Which documents that you refer from rocketboards for your booting process?

    We used the guide at https://rocketboards.org/foswiki/Documentation/BuildingBootloader#Agilex_45_Boot_from_SD_Card to build the bootloader and used the guide at https://rocketboards.org/foswiki/Projects/AgilexSoCSingleQSPIFlashBoot to build the userland using bitbake. We also modified the meta layer to include our device tree source file which I attached.

    Thanks for your help!

    Regards,
