I don't think it is possible to add Ethernet to the SPL - reason being, the small code size is meant for the HPS on chip RAM (64KB). Arria 10 meanwhile has much larger OCRAM at 256KB.

Yes, A10 support UEFI but CV does not. The other bootloader that Altera provides for CV is the MPL.

Okay, A10 seems to have much better options :cool: Would it be possible to place the u-boot binary in the EPCQ-flash and then using the boot copier load the u-boot binary into the DDR-memory? Is there support in EDS-tools for the boot copier? NIOS II SBT seems to have this nice feature.
