Yes, I was using the steps in https://rocketboards.org/foswiki/Documentation/UBootA10FPGABoot. The difference is that there is no longer a BSP editor in Intel SoC FPGA Embedded Development Suite v21.1.
"As part of the continuous enhancement of tools flow, Arria10 SoC BSP Generator functionality is now merged into U-Boot flow. "
I did change #define CONFIG_SYS_TEXT_BASE 0xc0000000, compiled u-boot, and ran:
arm-altera-eabi-objcopy -I binary -O ihex --adjust-vma -0x00000000 u-boot-dtb.bin u-boot.hex
The boot-from-FPGA did not work with the sof generated using the u-boot.hex. My guess is there is some additional configuration needed in u-boot (or the Qsys project).
