Honored ContributorHi all -
To revive a still-warm topic, I had a question about my first attempts at compiling and using the preloader and u-boot. I see the results here indicate that previous people have gotten further than me on the same board. My board is a 5CSEMA4U23 on the DE0-Nano-SoC kit and I want to be able to do some simple HPS clocking exercises. I have done the following: 1. Loaded the GHRD in Quartus Prime Std. 16.1 and compiled 2. Generated a .rbf binary file from Quartus 3. Used the EDS shell to access bsp-editor and create and subsequently compile both the preloader-mkpimage.bin and u-boot.img files 4. Placed both above files on the SDcard (using alt-boot-disk utility in EDS for the preloader) and added the system .rbf and *.dtb files to the SDcard 5. Tried to boot up Assume that I have a (previously) working clean kernel of Linux which can be acquired from Terasic (http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&categoryno=205&no=941&partno=4) and that initial boot of the Linux fs was successful. Assume also I am interacting via putty serial to my board. I did these steps following the instructions for the Arrow SoC kit dictated by Kris Chaplin at Altera (https://www.youtube.com/watch?v=vs7pvefsbrm) but I get no data/boot when I run the new SD setup. What is missing? Thanks if you can lend any insight. I did not change any settings on the project from the GHRD, so I imagine the issue is simply something missing or incorrect with the preloader or the u-boot step. Since I can't even get an output from my device over serial maybe it is the preloader.. stumped.
