Hi

Please find attached the uboot i am using.

Going through the device tree I see that the is a difference in the mmc node between yours and mine.

Are you using a devkit or a custom board? If it is a custom board, are you use an 8 bit sd card or a 4 bit sdcard?

Could you try changing your mmc node in the device tree to below:

&mmc {

status = "okay";

bus-width = <4>;

sd-uhs-sdr50;

cap-mmc-highspeed;

bootph-all;

};

Regards

Jingyang,Teh

    Hi

    I'm Using Agilex 7 FPGA I-series transceiver-soc development kit(4x F-tile).

    Unfortunately the shared u-boot is not working with my board.

    It stops at "## Checking hash(es) for config board-0 ... OK."

    I need to build u-boot for Agilex 7.so sharing u-boot source will be very useful for me.I'll compile and debug according to our need.

    Thanks
