Common Support Modules

The files in directory \D.SignT\Network\DM2DM642EMAC\Common are not required to use with the TCP/IP stack but could facilitate the development. All the Support SW examples make use of these modules

This directory includes:

Common.c	- Common Support Functions: Implementation
Common.h	- Common Support Functions: Definitions and Prototypes
cprintf.c	- Custom printf Functions: Implementation
cprintf.h	- Custom printf: Definitions and Prototypes
nbuffer.c	- Network buffer management: Implementation
nbuffer.h	- Network buffer management: Definitions and Prototypes
timer.c	- DSP timer: Implementation
timer.h	- DSP timer: Definitions and Prototypes
uartio.c	- UART IO: Implementation
uartio.h	- UART IO: Definitions and Prototypes
user_input.gel	- User input
xdump.c	- Hex Dump Functions: Implementation
xdump.h	- Hex Dump: Definitions and Prototypes

Link information:

Use the following linker instruction to link these modules to external memory:

Application linker command file App.cmd:

/* #define COMMONSECTIONS  IRAM   all common modules linked to internal RAM */
#define COMMONSECTIONS    SDRAM  /*  all common modules linked to external RAM */
#include "../../../Common/CommonSections.cmd"

Linker command file \Common\CommonSections.cmd:
