Cyclone V SoC Preloader will not run bare metal app

Thank you for your answer austin944.

I followed your advice and I made a great step forward, although I'm still not able to boot the application.

I changed the linker file and mapped all the oc_ram sections to sdram, i.e. at positive address.

Now all sections in 0xffff0000 have zero size like in your example and infact I can now generate an image file with a reasonable size!

I'm now stuck on another weird point.

I created the following img file with mkimage an put it on sdcard.

It gets loaded into sdram but, if I inspect memory after the fatload command, I see the data (which is correct) is misplaced.

To me it seems an endianess problem, since I see the low and high words swapped.

For example, at address 0x100000 I'm supposed to have 0xE59F F018, but I find 0xF018 E59F
