Which code in SRAM4 for LPBAM?

[JoachimO]

Hello,

In the example projects for LPBAM from ST, it is necessary to switch the RAM address to the SRAM region. 

This is because LPDMA has in Stop2-Mode only access to SRAM4.

If I also want to use the RAM, which part of LPBAM (or maybe other parts) must be in SRAM4?

 

It is described here, for example:

Thank you,

Joachim

Dear @JoachimO ,

Here are a link for LPBAM features and which RAMs can be used by Peripheral and system:

Let us know if we need something to improve in the available ressources .

Hello,

In this document there is the following statement:

To do so, In the STM32CubeIDE, in Project Explorer > Debug, go to the STM32U575ZITXQ_FLASH.ld and configure the RAM ORIGIN = 0x28000000 and the LENGTH = 16 Kbytes

 

The consequence of this is that I only have 16 kbytes of RAM available for this project.

Is that right?

Is there another way to use the remaining RAM?
