4MB Flash layout setting

I’m using a translation and I’m a beginner, so I apologize if the information is incorrect.

I have a NORA-W30 series board.

How to change the flash layout from the default 2MB to 4MB

I found a document with instructions when using the Standard SDK.

9.1.4 4M Flash Usage Example

But I can’t find a way to change it when using the Arduino SDK.

Could you please tell me the document or how to change it?

Hi, currently it is not support for update the size of flash.

Thank you for your reply.
I will check regularly from now on to see if it is supported.
