The memory size of STM32WBCG55 in STM32CubeIDE doesn't match to the datasheet.

Hi, stm.

The build analyzer of the CubeIDE showed the full memory size and the usage. When I build my custom project of stm32wb55cg, the size of flash and ram did not match to the datasheet.

The below image shows the result.

0693W00000VOkMPQA1.pngIn the datasheet, the flash and ram size are 1MB and 256KB.

How to configure full size of the memory?

Thank you

CPU2 has exclusive access to parts of SRAM2 and Flash, so these parts are not user accessible, see "5 Memory mapping" in datasheet.

Hello,

The memory size shows in build analyzer of the CubeIDE correspond to memory size defined in the scatter file (see STM32WB55RGVX_FLASH.ld file).
