Hi guys, As I want to now more about the design flow for developing on the Cyclone V SoC, I decided to create a new design, which allows to run a simple LED application on the NiosII processor ...

User Guide "from Altera" will be only I & You will write it here ! :)

My experiments in May & June was in 13.1, I modify a Preloader with "while (1) ;" in function that load my application from QSPI and goto it, fill Preloader & App to QSPI with Altera utility, power on board, connect with DS-5 to cycling Preloarer, change PC to next line and see execution step by step. No problems was with QSPI, only with code, rev. of my board is don't know.

I think that address of memory is not significant -- memory is visible cyclic from 00100000 to C0000000.

Please quote all your commands to make a binary image of Unhosted application and fill it to QSPI, analogical for Preloader.

ECC checking may be set off in bsp-editor, I also make off WathDog.

Current version of SoC is (very-very) not compatible with Baremetal -- wait and wait good ARM-developers in Altera & writing for us good manuals...
