I am using Altera DevKit with SOCEDS 14.0. 

 The system boots from QSPI where 2 preloader images  Is there way to force load from specified image?

However there is a HW register in the system manager that allows a subsequent warm boot to choose any of the images to boot from.

Hi 

 So my understanding is Boot 1st preloader from address 0, config hw register to set address of 2nd preloader, do warm reset. Is it correct? Is the register name ALT_SYSMGR_ROMHW?
