Occasional ContributorHello서박사,
I’m glad that your problem has been fixed.
So I will close this thread if no further questions from you.

Occasional ContributorHello Yoshiaki,
Sorry for the wrong logs for accessing the data register.
I've checked the value at the register which corresponds to the HPS-FPGA bridge changes properly while U-Boot, and the logs are as follows:

In addition, .qsys file is compressed to .7z file and attached this reply, so please find it.
It is based on the project "DE1-SoC_Computer " which is provided by Altera University Program.
The .rbf file is based on the attached .qsys file, .dtb file is based on the Terasic Ubuntu image and zImage is provided by releases.rocketboards.org.
I've tried to use all files from Terasic Ubuntu image, but in this case, I couldn't boot the device.
For your information, .dtb file and zImage file are also attached to this reply.
Thank you for your devotion!!
Occasional ContributorHello Hi서박사,
Basically, you should build DTB from DTS in same Kernel tree.
So could you please try the latest Linux Ubuntu Desktop(2016-12-28) in new SD-CARD again just in case?
Lastly, Bus size of LED is 32 bit as below. You should use md.l or md command to access the port instead of md.w.
2.3.1 Red LED Parallel Port

Using the latest Linux Ubuntu Desktop (v1.0, 2016-12-28) from Terasic resource center, U-boot fails with the following logs.

I really appreciate your time and effort on this thread.
Thank you!
Occasional ContributorI think I found the error source and fixed it.
The main reason was the malfunction of the clock source at the FPGA.
In the attached .qsys file, almost all FPGA components are based on the output clock of the PLL, which reference clock is provided by PIN_AF14.
However, I found that this clock source is not working.
I revised the system configuration to take a clock source from PIN_K14, not from PIN_AF14.
Thus, everything works well.
The logs are as follows:
root@DE1_SoC:~> ./memtool FFD0501C 1
Reading 0x1 count starting at address 0xFFD0501C
0xFFD0501C: 00000000
root@DE1_SoC:~> ./memtool FF200000 1
Reading 0x1 count starting at address 0xFF200000
0xFF200000: 000003FF (This result is intended)
I'm sorry for making this thread to be too long since I'm not familiar with the embedded system, including FPGA.
And again, I really appreciate your time and effort on this issue.
Thank you!!
