There is a workaround currently to load the code at the moment.

It is a small code to delay the nios processor while the flash initialized.

You could set your project to run from the OnChipRam IP with the application initialized and your actual application will be stored in the Flash.

The application first run on the OnChipRAM will delay the nios till the flash is initialized and jump to the flash device and it will run the bootcopier that will copy the code to the DDR and finally jump to the DDR.
