Using RAM Devices

Using RAM Devices explains how to create applications for RAM Flash devices.

Include into the project and configure the following source files:

1. The library that matches the device core:
   FS_CM3.lib for Cortex-M devices.
   FS_ARM_L.lib for ARM7 or ARM9 devices.
2. The configuration files:
   File_Config.c for configuring the device.
   Retarget.c for configuring the output.
3. The main file for initializing and connecting the Flash device.

4. #include <RTL.h>

5.

6. int main (void) {

7. ...

8. finit (NULL); // initialize the device

9. fformat (""); // format the Flash File System

10.

11. while (1) {

12. ... // add the code

13. }

14. }

Applications can be created using existing µVision projects as templates.

1. Copy all files from any folder \ARM\RL\FlashFS\Examples\File_ex1 to a new folder and open the project *.uvproj with µVision.
2. Open the file File_Config.c and configure the RAM device using the Configuration Wizard.
3. Enable RAM Drive and set the device characteristics.

1. Modify the code to the application needs.

Note

• Configuration options are explained in RAM Drive.
• Additional program examples for RAM devices are located in the folder \ARM\Boards\vendor\board\RL\TCPnet\TFTP_demo.
