Arria 10: Linux Kernel Configuration

[PJais1]

Hello ,

I am designing linux OS for our custom board which took reference from Arria 10 SoC. While building u-boot , I did changes in qsys for all the hardware modification at HPS side , so that a .sof file is generated which build a uboot_mkpimage.bin .

But I am confused with the kernel configuration , I took reference from https://rocketboards.org/foswiki/Documentation/A10GSRDGeneratingTheLinuxDeviceTreeLTS

which indicated that a dtb file is generated which is required to boot linux kernel.

This file is generated using sopcinfo and board xml files.

In order to boot the custom board , do we need to make any change in sopcinfo or board xml files , as we did in uboot build ?

If so ,how to modify xml files?

please do reply.

Thanks,

Priya

Hi,

In my understanding, if the changes in Qsys have connections with the HPS it needs to be rebuild.

Have you check the HOWTO Create a Device Tree:

There are sections for Arria 10 SoC, I recommend that you check it out.
