/** * MEM_ALIGNMENT: should be set to the alignment of the CPU * 4 byte alignment -> #define MEM_ALIGNMENT 4 * 2 byte alignment -> #define MEM_ALIGNMENT 2 */ #ifndef MEM_ALIGNMENT #define MEM_ALIGNMENT 1 #endif
It seems the default setting of MEM_ALIGNMENT is 1.
And TI recommends MEM_ALIGNMENT probably best set to 4 for this device as it is a 32 bit (4 byte) CPU.
