we currently building a board with the Cyclone V SOC. This Board is based on the de0-nano-soc evaluationboard and i used the U-Boot(v. 2017.05)-de0-nano-soc-project to create our own bootloader.
Problem: If i use the provided µSD-card from Terasic, our board boot without any problems. If i change the u-boot.img file with my own u-boot file or with the new build de0-nano-soc-file, the EMACs wont work.
Error: ethernet@0xff700000 address not set.
Error: ethernet@0xff702000 address not set. (only when i change the emacs)
I don’t mind if i get only one or both EMACS working… But i really stuck here. Any Ideas?
I looked in the device tree file from the SD-Card, no differences. I changed the PIN_MUX. Nothing seems to help
I’m really new with U-Boot and FPGA’s and SOC’s
Thanks for the Support
