Why do I need to change the order of memory zones to make my program link?

[tamir_michael]

Hello,

I have a program based upon i.MXRT1064 that can only use internal RAM. If I allocate a large buffer (>600KB), in order to avoid linker errors due to a placement failure I must also move the SRAM_OC region to the top of the list of memory regions.

Why is this needed?

Hello, Tamir 

By default, global data items are located at run time in the ‘default’ memory region (i.e. the first
RAM block displayed in the memory configuration area).

Have a great day,
Victor
