STM32F407IGTx STCubeMX strange values

Hello,

I would like to know why if you are building a project with code-generated makefile for the MCU STM32F407IGTx (QFP176 pins) the linker file STM32F407ICTx_FLASH.ld tells the compiler the RAM origin at 0x20000000 has a length of 128K instead of 192K.

And another question is: I connected two STATIC RAM CHIPS (IS61VW5128BLL 512Kx8) in the STCubeMX telling wich I am using TWO CHipSelect for this two chips. Everything in compiled correctly.

Now I want to place some code in this external RAM address (total of 1024k - 512k + 512k). I would like to know how to setup the linker file for this area (without declaring two area-spaces))

Thank you in advance

Regards,

Gianluca
