Hello,

Please refer to the following application note. Although for this document we use the RT1050, the same concepts apply for the RT1060.

How to Enable HyperRAM with i.MX RT (nxp.com)

I have referred to this document. This is explaining about the enabling the peripherals and accessing the hyperRam.

With the same config can I copy the codes into hyperRam and start executing it from there ?

I am trying to do something like this.

I have a u-boot, which is relocating the linux kernel from sd card to SDRAM. Trying to modify this and relocate the code to hyperRam instead of SDRAM. I am able to finish the relocation, but encounters issue when starts the execution.

Is there any specific config I need to take care before starts the code execution?

Hello,

I apologize for the misunderstanding, it's not possible to boot from an HyperRam memory. The intended use of the HyperRam is to use it as described in the application note that I shared before.
