Using NAND Devices
Using NAND Device explains the steps to create applications for NAND Flash devices.
Include into the project and configure the following source files:
- The library that matches the device core:
FS_CM3.lib for Cortex-M devices. FS_ARM_L.lib for ARM7 or ARM9 devices. - The driver file NAND_device family.c containing the functions for NAND Flash devices.
- The configuration files:
File_Config.c for configuring the device. Retarget.c for configuring the output. - The main file for initializing and connecting the Flash device.
5. #include <RTL.h>
6.
7. int main (void) {
8. ...
9. init_nand (); // provide the code to initialize the NAND device
10. ...
11. }
Applications can be created using existing µVision projects as templates.
- Copy all files from any folder \ARM\Boards\vendor\board\RL\FlashFS\NAND_File to a new folder and open the project *.uvproj with µVision. RTX projects are using the RTX-RTOS. However, the configuration does not differ.
- Open the file File_Config.c and configure the Flash device using the Configuration Wizard.
- Enable NAND Flash Drive and set the device characteristics.
- Provide the code for the NAND driver functions.
- Define the NAND Page Data Layout.
- File Time Support Routines might need adaptation to set time stamp for the file.
- Modify the code to the application needs.
Note
- NAND Flash Drive described the configuration options for NAND devices.
- NAND Flash Translation Layer describes the NFTL features.
