Honored ContributorLoading NIOS from SRAM Arria V GX Starter
I am trying to configue NIOS to load from SRAM on the Arria V GX Starter kit. I have set up the system in Qsys and have attached the data master and instruction master to the tri-state controller that is driving the SRAM. If set NIOS to boot/load from on chip memory, the everything works fine. I can even write/read to the SRAM from a program running in NIOS. But if I change the reset/exception vector to the SRAM component, I get a verifying failed error when trying to download the .elf file to NIOS. What am I doing wrong? Am I making some stupid mistake somewhere?
Does anyone have a qsys based example of NIOS loading from off chip memory on the Arria V GX starter kit? (Any one of the off-chip memory components would work for me. I just can't afford to eat up so many M10K when using the on-chip memory method. I've also tried setting up the ddr3 with no luck.). I really need an example specific to the hardware on the Arria V GX board. I've successfully setup other board using ddr2 ram without any glitches. Any help on this matter would be greatly appreciated, thanks in advance.
