Hello KAWAZOME Ichiro,
I want to work with my project that i developped on quartus but, when I want to change .dts and .rbf, kernel doesn't work. I think i have to work with dtbocfg-ctrl but I don't konw how can I do this modification, do you any explaination ?

Thank you

Hello

Examples of DE10-Nano and Quartus can be found at the following URL. Please refer to this.

Thank you for your answer but, when i try to launch "sudo rake install" with this example, i have this issue :

:3.17-32.5: Warning (avoid_unnecessary_addr_size): /uio-irq-test@0: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property
:14.22-18.20: Warning (interrupts_property): /uio-irq-test@0/overlay/pump-uio@43c10000: Missing interrupt-parent
can not udmabuf installed.

did you have already the same problem ? Do you have any solution ?

I'm sorry. I also checked here. The first rake install immediately after booting may fail. If that fails, try rake uninstall and then rake install again.
