I found it strange that the sd_image_mitysom_5cse-l2-3y8_dev_kit.bin did not properly boot also. So I pulled another SD card from a different dev board and wrote the image to it, and it properly booted. Then I loade...

- Hello Brian,
That is very odd that you are still seeing that error with the sd_image_mitysom_5cse-l2-3y8_dev_kit.bin. I just double checked that image and was not able to recreate the errors in your boot log, it booted an got an IP as... - BW 04:48 PM Software Development: RE: Board info files MittySOM-5cse-l2-3y8

Are you trying to manually by hand create the DTS or are you using the Altera Sopc2dts tool that will take the output of your quartus build and create the DTS for you?
We normally go about creating the DTS by hand. The... - I'm having trouble creating a dts file that shows the peripherals on the fpga of my design. I can't find the correct xml board info files needed to create the dts file. Any help would be appreciated. The goal is to create all the necessa...
