5.3. Nios® V Processor Booting Methods
There are a few methods to boot up the Nios® V processor in Intel FPGA devices. The methods to boot up Nios® V processor vary according to the flash memory selection and device families.
Supported Boot Memories | Device | Nios V Booting Methods | Application Runtime Location | Boot Copier |
---|---|---|---|---|
Configuration QSPI Flash (for Active Serial configuration) | Control block-based devices 4 (with Generic Serial Flash Interface Intel FPGA IP) | Nios V processor application execute-in-place from configuration QSPI flash |
Configuration QSPI flash (XIP) + OCRAM/ External RAM (for writable data sections) | alt_load() function |
Nios V processor application copied from configuration QSPI flash to RAM using boot copier | OCRAM/ External RAM | GSFI bootloader | ||
SDM-based devices 5 (with Mailbox Client Intel FPGA IP) | Nios V processor application copied from configuration QSPI flash to RAM using boot copier | OCRAM/ External RAM | SDM bootloader | |
On-chip Memory (OCRAM) |
All supported Intel FPGA devices 6 | Nios V processor application execute-in-place from OCRAM | OCRAM | No boot copier required |
