Custom linux image build failure for Arri10 SoC development kit

Hi

Are you following the steps from rocket board below?

https://www.rocketboards.org/foswiki/Documentation/Arria10SoCGSRD

Have you made changes to the original branch? Because by default the linux branch it is supposed to use is socfpga-6.1.68-lts

Hi Jingyang,

I am able to build the image successfully by removing the linux-socfpga_6.6bb (which is causing the error) blindly following the steps mentioned in the documentation. But I have below questions

1. Where can I include my custom device tree source files and re-build the image?

2. Where can I make changes so that the image mounts to /mnt folder instead of /dev/mmcblk02

Thanks

Sai

Hi

Please find my response below:

1. Where can I include my custom device tree source files and re-build the image?

You could directly make changes to the device tree source file (socfpga_arria10_socdk_xxx.dts )in the repo that you have clone in your work directory. There are two level of device tree you will need to edit. One for the uboot and one for linux:

uboot

u-boot-socfpga/arch/arm/dts

linux

linux-socfpga/arch/arm/boot

/dts

2. Where can I make changes so that the image mounts to /mnt folder instead of /dev/mmcblk02

What do you mean the image mount point? Which image mount point are you referring to?

Are you referring to the linux image? The linux image needs to be from a dev eg. QSPI or sd card.

Hi Jingyang

Thanks for the response

I have tried only maiking changes in one level i.e. in linux.

I will try changing in both uboot and linux.

Apart from that, I have a general question. I have built the image without making any changes to dts, means I just reproduced the steps mentioned in rocketboards documentation. Image build was successful but I am not able to boot the board. There is nothing shown up in the bootlog

The board details I have are

Serial Number: 10ASXSoC003452 Rev C

Serial Number: 10ASXSoC003968

Thanks

Hi Sai

Just to confirm you are working with the board below:

https://www.intel.com/content/www/us/en/products/details/fpga/development-kits/arria/10-sx.html

Instead of trying to build the binaries, could you try running the pre-built binaries to check the board is able to boot up?

Hi Jingyang,

The board is booting up with the pre-built linux binaries.

So, I can use pre-built .itb and uboot.img for initial booting and I can use .dtb and zimage files built by me for my application. Correct me if I am wrong.

Thanks

Sai

Hi

Thats great, that meanst he board is working properly.

Next step lets try the steps on generating the GSRD.

You could follow the steps below:

https://www.rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10#Arria_10_SoC_45_Boot_from_SD_Card

It is the steps to build to boot from SDCard like the GSRD.

Hi

Any update om this case?

Are you able successfully generate and run the generated GHRDbinaries?

Hi Jingyang,

Sorry for late response.

I am able to build the dtb files after adding custom dts files. But I am facing bitbake errors while building rootfs using yocto, after adding custom recipes.

With Regards,

Sai

Hi Sai

Are able to build the linux image without adding your custom recipe?

What are the error message that you get after adding custom recipe?
