i want frdmk64fn1m0vll12 data flash write API function

[sudhakarp]

Hi,

     using KSDK 1.1.0 flash demo project i tried to write some data on flash but i am getting error response. i dnt know

why. can you give any solution.

     in "frdmk64fn1m0vll12" EEPROM is not there..?

here is my code..

TRIED METHOD-1:

uint8_t sudha_data[]="hi";

   destination = flashSSDConfig.PFlashBase + PFLASH_IFR;

   ret = FlashProgram(&flashSSDConfig, destination, sizeof(sudha_data), sudha_data, g_FlashLaunchCommand);

TRIED METHOD-2:

    ret =FlashProgramOnce(&flashSSDConfig,0x1,sudha_data,g_FlashLaunchCommand);

         if (FTFx_OK != ret)

         {

             ErrorTrap(ret);

         }

         else

         {

             printf("\n\rsudha ERROR");

         }

  thanks and regards,

Hello,

In order to isolate the issue, if you run the flash example code (C:\Freescale\KSDK_1.1.0\demos\flash_demo) without modifications,can you reproduce the issue?or this issue is when you add the write code

hi Soledad,

     i am waiting for your reply..

          is possible or not.? minimum 2kb data i want to write into internal flash and i want to read.

give some idea. i saw example code also but that one was not working. i mean i am doing some mistake i dnt know exact.

i tried both function

WRITE OPERATION:

1) ret = FlashProgram(&flashSSDConfig, destination, size,  program_buffer, g_FlashLaunchCommand);

2)ret = FlashProgramOnce(&flashSSDConfig,0x2,buff_data, g_FlashLaunchCommand);

READ OPERATION:

ret = FlashReadResource(&flashSSDConfig,destination,sudha_data,0x0, g_FlashLaunchCommand);

     may be i am doing mistake in "destination address". so can you edit code like 2kb data WRITE and READ from flash..

Thanks and regards,

Hi soledad,

          this issue was after adding flash "WRITE" API function. i want to write 4KB  data into flash and again i want to READ that data. can you give solution for this..? could you tell which function i want to use..?  can you give simple example code for this...

thanks and regards,
