HPS QSPI flash programming

Hi,

I have an issue with QSPI flash programming by quartus_hps utility. I use EDS 14.1 and run quartus_hps in its command line. I've made custom preloader to boot from QSPI flash and program the memory device. The software placed preloader images 4 times in the very begining of the memory so it seems to be good. But after I repowered my board and saw that preloader had started I can't program flash memory again! The programmer try to read silicon ID but it fails and the whole operation stops. How could I fix this problem? What am I doing wrong?

Thanks.

    This is seems like a continuation of another post earlier, I think what he did was erased the whole qspi blocks and reload all the preloader and hello image.

    Use the flash_erase all the partition , and then reflash new content again.
