Arria 10 : Uboot Configuartion Settings

Hello,

I am building linux OS for our custom board which took reference from Arria 10 SoC .

I build u-boot image by taking reference from https://rocketboards.org/foswiki/Documentation/A10GSRDGeneratingUBootAndUBootDeviceTree

and boot from SD card https://rocketboards.org/foswiki/Documentation/A10GSRDCreatingAndUpdatingTheSDCardLTS

But the uboot is not booting when board is powered on.

As I am using custom board, i did changes in qsys file in quartus tool and generated .sof file according to our pin muxing at HPS side.

I am having a doubt that while generating uboot.mkpimage.img do we need to make changes in uboot-socfpga folder ? and if so, where do i modify these changes?

Thanks,

Priya

    Hi,

    Did you replace the DDR module? If yes may I know the data sheet for the DDR that you are using?

    Which quartus version or you using? Can you share the uboot log?

    Hi,

    After getting the new generated sof files, the handoff folder will be generated as well according to the new compilation.

    Thus, a new uboot img need to be made again by the "make uboot" command in SoC EDS based on the new generated handoff folder.

    I hope this is clear.
