I followed the tutorial series https://www.youtube.com/watch?v=JxhKmVUB2Ws&list=PLnMKNibPkDnFQXYK0ztHV9iMVS6EAtKpD&index=10. And i tried allthing and i applied successfully at my eval board. But the mce is so different. In the tutorial the instructor used different board hence the board is using mce1. But i'm using the mce2 because the xspi2 connected mce2. And the mce2 couldnt support the aes.
My memory write and memcopy methods;
