How to boot baremetal code from sd card

Why Nios there? This part of Altera Forum is about Cyclone V FPGA with internal ARM cores!

To SD card I not may write my hwlib.bin (maked from hwlib.axf) through quartus_hps.exe on address 60000 or any, however to QSPI -- plainly, because there no MBR and filesystem, probably. And booting not work always :(

I will get there from Altera Guru-s detailed rules to fill my any DDR3s-hwlib.axf to QSPI flash or raw partition of SD-card, to make in mind and practice full path of Baremetal application developing -- so that after repower kit board LEDs will blinking!

Using or not RTOS, Linux ets. -- trouble of author of sources and its system architector/boss, I generally don`t need in "universal" fashionable garbage collections in my projects, using 100 M of ROM/RAM and booting more than 1 second.

Using HAL to polling all system contents in one simple "thread" and processing in turn all of ingoing events are very effective in embedded applications.
