5.5. Nios® V Processor Booting from Configuration QSPI Flash

The Nios® V processor supports the following two boot options using configuration QSPI flash under Active Serial configuration mode:

  • Nios® V processor application executes in-place from configuration QSPI flash.
  • Nios® V processor application is copied from configuration QSPI flash to RAM using boot copier.
