  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
	#define AM7XXX_PRINTF_FORMAT printf

  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.

data/libam7xxx-0.1.7/examples/am7xxx-play.c:714:16:  [3] (buffer) getopt:
  Some older implementations do not protect against internal buffer overflows
  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
