RAM allocation

[Georgiy Lutsenko]

Hi all

I have a problem with allocate RAM.

I build the project as non secure.

in the zephyr.dts file, you can see that the memory is divided into 3 areas:

sram0_s:image_s@20000000 {
register = <0x20000000 0x16000>;
};
sram0_modem: image_modem@20016000 {
register = <0x20016000 0xa000>;
};
sram0_ns: image_ns@20020000 {
register = <0x20020000 0x20000>;
};

How to reallocate memory to increase sram0_ns?

Hi

This is not the file to increase/edit the allocated memory in, as this file will be overwritten by the Partition Manager which is a Python script that sets the start address and size of Flash/RAM partitions in a multi-image build context. Please check out the documentation, as I think that should explain pretty well how to allocate RAM as you wish.

Best regards,

Simon

Hi Simonr
Thanks for the answer
I was able to increase the size of Sram non secure. To do this, I added the pm_static.yml file to the root directory, changing the sizes and addresses of existing partitions, but I'm worried that when partition_manager_report is run, there are no changes, and when ram_report is run, it gives an error. Also, there are no changes in the device tree.

Best regards,

Georgiy
