I'm currently trying to follow up several tutorials on creating a preloader and bootloader for an Intel Cyclone V Soc. For example I did all steps from this tutorial:
After creating the preloader and bootloader in EDS Command Shell ("make" and "make uboot")
I transfer it to the FAT partition on my SD card drive G:
( "alt-boot-disk-util.exe -p preloader-mkpimage.bin -a write -d g" and "cp uboot-socfpga/u-boot.img /cygdrive/g")
But when I put the card into the Terassic DE 10 Nano Board it will not boot.
I see the following output in Putty:

I checked all steps but I didn't find the issue.
Can someone help me?
Thank you very much.
