Hello 서박사,

I have been similar experience with wrong DTB.

Please check DTS(DTB) first.

Hello Yoshiaki!

Thank you for the prompt answer.

I've tried to replace DTB file from GHRD and I think it worked for me to boot the device.

Also, replacing zImage file from GHRD also worked.

However, although the device has been booted successfully, I cannot run any program using Altera function.

I've opened an individual thread for this issue a few days ago, so I would not ask you for the aforementioned issue here.

I'm still confused why the DTB file from the reference image (https://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&No=836&PartNo=4) is wrong.

For this, is there any method to check if the DTB file is "proper"?

(I don't think DTB and zImage are related to each other, but DTB and .rbf file are related together)
