Getting back a physical address from virtual address

Hi All,

I am currently working on SRAM and I use mmap for getting the virtual address.

Now my requirement is to get back the original physical address from the generated virtual address.

Please provide the steps to get the physical address.

Hi @syedr1

I hope you are doing well

The details regarding the Management Unit (MMU) and virtual to physical address mapping are mentioned in section 2.1.4 Memory Map of the i.MX Reference Manual,

To learn more about the Memory and MMU, kindly refer to the below NXP document

Memory Management Unit

I hope this information helps you.

Thanks & Regards

Dhruvit Vasavada
