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,

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,

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,
