Arria 10 : Uboot 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
