Compiler/MSP430FR2155: What is the best way to allocate the variables stating at a specific RAM address

Hi Experts,

I understand that similar questions were posted on the forum but please let me allow to ask the question.

My customer wants to allocate the variables(INT) starting from a specific RAM address. For example, there are 3 variables starting at 0x1000.

var 0 @0x1000

var 1 @0x1002

var 2 @0x1004

Now they add the new variable var 3 and they want to allocate it at the bottom of the variables as below.

var 0 @0x1000

var 1 @0x1002

var 2 @0x1004

var 3 @0x1006

What is the best way to do this?

Regards,

Please search the MSP430 compiler manual for The LOCATION Pragma. This pragma is used to locate a variable at a specific address.

Thanks and regards,

I was looking for the way once define the location, all variables linked to that location are placed in order and the order is not changed every compiled. But I understood that we need to use LOCATION pragma for each variable.

thanks,
