[U-Boot] DE10 Nano U-Boot v2019.04 Issues

[rafael mello]

Hello Simon,

Adding the "clock-frequency = <100000000>;" line to the dts file solved the issue, But I had found another solution before reading your repply.
There is one dtsi file missing for the de10 nano board, the file should be named "socfpga_cyclone5_de10_nano-u-boot.dtsi" and it's content should be the same as the "socfpga_cyclone5_de0_nano_soc-u-boot.dtsi".
For some reason the "*-u-boot.dtsi" files are loaded even whan not called in the dts file, and the clock-frequency definition was in that file for all the cyclone5 boards, except for the de10 nano. Creating the file made the board follow the current pattern/standard and solved the issue.
Maybe a patch is required.

I'm attaching the socfpga_cyclone5_de10_nano-u-boot.dtsi file and the socfpga_cyclone5_de10_nano.dts files

Thank you  very much for the help, even with the solution that I found, I failed to see that the clock-frequency was the real issue.

Best regards,
Rafael Villatore

OK, so there's probably something wrong with getting the console.
After checking that dts,
could you add the following line to the &uart{} node in the de10 dts:

clock-frequency = <100000000>;

If that still doesn't work, try to enable debug uart to see any output.

Ah, no, I failed to see the "de10" vs. "de0". However,
