Hi Jayasurya,


Can you elaborate more regarding the custom card which you have mentioned? Would like to know what is the changes as compared to a default dev kit.

Just to confirm, are you currently booting up with SD card or QSPI flash?

May I know how you enable the changes in the Uboot device tree to consider the hardware changes?


Thanks.

Regards,

Aik Eu

Hi Aikeu,

Thanks for the reply.

We have changed the level translator, ESD diode part number compared to the reference design.

I have done the changes in the device tree file(arch/arm/dts/socfpga_agilex_socdk-u-boot.dtsi). In my custom board DDR size has changed from 8GB to 4GB. I have attached the dts file for your reference.

I have loaded the .jic file in the QSPI, so that FSBL will load from QSPI and I am trying to boot from MMC(SD Card).

Best Regards,

Jayasurya R.
