Is it possible to boot Nios V processor from on-board SDRAM?

[BXia]

Hi, I have a project includes Nios V processor, as on-chip memory is small size, I have to use on-board SDRAM to boot Nios V processor. "The boot memory is the Quad Serial Peripheral Interface (QSPI) flash, On-Chip Memory (OCRAM), or Tightly Coupled Memory (TCM)." is described in Nios® V Processor Configuration and Booting Solutions, I'm not sure if on-board SDRAM can be considered as TCM, then my question, could Nios V processor boot from on-board SDRAM? Thanks.

Hi

Yes NiosV could be run from SDRAM.

However, it is slightly different.

You would need to add in the EMIF controller to connect the SDRAM.

In the BSP setting instead of selecting the OnChip Memory you would select the SDRAM(EMIF controller)

Instead of initializing the OnChip Memory with the Application hex.

You would need to store the hex in a flash device and with a boot copier copy the application to the SDRAM.

You could take a look the steps here:
