I also don`t may start from QSPI or write new Preloader to SD-card.

Remake Preloader, fill it to 0 address 4nd with quartus_hps, application (Altera BareMetal example for 4 diodes mighting GNU) fill to 60000 -- don`t boot on power on.

In DS-5 debugger runs a copy of Preloader, it inited DDR, loads my application from QSPI to DDR at 02000000, check CRC succsessful, I through "file hello.axf" loads debug-info for application, steps in debugger, and in _initio() hang!

My application with HPS-jumpers 28-30 in pos right-left-left from manuals also is not started in DS-5! And with default left-right-left successful started.
