Honored ContributorI can't, because all quartus_hps commands are based on reading of QSPI flash ID/status, but it fails. For noe I've found out the problem is in QSPI controller, it generates SCLK clock only after HPS reset to read previously loaded data and hangs immediately after this. I view htis clock with oscilloscope and I can see that QSPI controller doesn't work well. I've also tried to reach flash device via Altera QSPI example. But the function of reading silicon ID hangs due to the reason I described. What's wrong with QSPI? How preolader code, loaded to flash can block this core?
