sdram base address in HPS

[RShal4]

Hello,

In user's guide for baremetal (

https://www.intel.com/content/www/us/en/programmable/documentation/lro1424280108409.html )

The application is linked to 0x02000000 (using scatter file) of sdram in size of 32M.

But cheking cyclon V HPS reference manual

I see that SDRAM is actually mapped to 0x00010000 until 0x80000000

Why is the guide using a different base address for sdram ?

Thanks,

ranran

Hi,

The 0x02000000 address in the baremetal user guide is the start address specifier in the scatter file for the SDRAM. It is not the base address.
