4.5.2.1.1. Hardware Design Flow

The following sections describe a step-by-step method for building a bootable system for a Nios® V processor application copied from configuration QSPI flash to RAM using SDM Bootloader. The example below is built using Intel® Stratix® 10 SX SoC L-Tile.

IP Component Settings

  1. Create your Nios® V processor project using Intel® Quartus® Prime and Platform Designer.
  2. Add the Mailbox Client Intel® FPGA IP into your Platform Designer system.

    Figure 52. On-Chip Memory (RAM or ROM) Intel FPGA IP Parameter Settings
  3. Change the On-Chip Memory (RAM or ROM) Intel FPGA IP Parameter Settings according to the memory function. Ensure that you have the following memories in the system.
Memory Memory Type Total Memory Size

Memory initialization
Bootloader ROM

ROM (Read-only)

6144 bytes or more
Enable the following settings:
  • Initialize memory content
  • Enable non-default initialization file with bootcopier_rom.hex
Bootloader RAM

RAM (Writable)

6144 bytes or more

 Leave all settings unchecked.
User Application RAM

RAM (Writable)

Depends on your application 4

Leave all settings unchecked.

Reset Agent Settings for Nios Processor

  1. In the Nios® V processor parameter editor, set the Reset Agent to Bootloader ROM.
