AWR1642: MMW_ALLOC_BUF start address of azimuthIn problem

Hello,

MMW_ALLOC_BUF  is used for memory allocation for various demos at mmwave_sdk_02_01_00_04. My confusion is (see the figure below) :

why memory start address of azimuthIn  is after dstPingPong_end instead of heapL1start?

Here is the function at dss_data_path.c:

MMW_ALLOC_BUF(azimuthIn, cmplx32ReIm_t, dstPingPong_end, MMWDEMO_MEMORY_ALLOC_DOUBLE_WORD_ALIGN, azimuthInLen);
