Arria 10 SoC Boot User GuideのFigure 25. Selecting Boot from SD/MMC Device in BSP Editor Windowを参考に、uboot_w_dtb-mkpimage.bin作成し、alt-boot-disk-utilで書き込みました。
u-bootスクリプトを作成し、SDカードのFAT領域に自作アプリケーションとsocfpga.rbf、u-boot.scrを置いて、評価基板Altera Arria 10 SoC BoardにSDカードを搭載し、電源を入れると以下エラーが出ました。

u-bootスクリプトは以下の様になっています。
fatload mmc 0 0x02000000 sboot.bin;

・自作のsboot.binはDS-5デバッガでは動作しています。
このエラーはなぜ発生しますか?何か情報があれば教えてください。

Hi,
Can you provide the full uboot log?
Also, are you using Early IO Release?
