    Question about SRAM declaration at XMC4700

    Short question I work with a XMC4700 board
    Overall, the controller has 352 Kbytes SRAM

    from data sheet:

    PSRAM 1FFE 8000-1FFF FFFF hex 96 KByte
    DSRAM 2000 0000-2001 FFFF hex 128 KByte
    CSRAM 2002 0000-2003 FFFF hex 128 KByte

    My question, can I use 150 kByte contiguously as GRAM Buffer

    Where and how would I have to declare such an area (DSRAM+CSRAM)?


    Thank you for your help

    Hi,

    The RAM in the XMC4700 is splitted among 3 different ram blocks although linear addressable (see linker file).
    You need only to take care that the buffer you declare is 4bytes aligned.
