This allows to use a bootloader if needed. Moreover RAM2 is contiguous to the RAM, like this you benefit from all space. User can easily redefine the LD_MAX_DATA_SIZE using board.local.txt if it need to use RAM2 for specific purpose.

TIM7 does not exist and prevent build. How did you test the check variant example?
