5.5.1.2. Nios® V Processor Application Copied from Configuration QSPI Flash to RAM Using Boot Copier (GSFI Bootloader)

You can use a boot copier to copy the Nios® V processor application from the configuration QSPI flash to RAM when you require multiple iterations of the application software development and high system performance.

The boot copier is located at the base address of the HEX data, followed by the application. For this boot option, the Nios® V processor starts executing the boot copier software upon system reset, which copies the application from the configuration QSPI to the internal or external RAM. Once the copying is complete, the Nios® V processor transfers the program control over to the application.
