Hello,

It is not possible to initialize MRAM Blocks with a default value at boot up. In Stratix devices default values are only supported for M4K and M512 Ram Blocks.

When you have enough M4Ks free, set the implementation of the on-chip memory to M4K RAM blocks. Otherwise you will need an external Memory where you can store your program and a little bootloader can copy the program on start up to a m-ram block or you use the external memory as program memory.

Hope this Helps
