c90tfs_flash_driver - unable to erase and program

[Can_Do_bus]

I am using S32k144 - I am using design studio to run the code in debug mode.

My code runs in NVM, I am executing the following commands in my code to erase and then program the P Flash area, i.e erase the same sector and  followed  by writing to that sector.

The code works if I either erase or program i.e if I run the program once with the FlashProgram command commented, it will erase the sector. When I run it subsequently to execute FlashProgram command with FlashEraseSector commented out line, this setup works.

However when I try to execute them together as below, it doesn't erase.  What is the issue

FlashEraseSector(&flashSSDConfig, flash_prog_address, FEATURE_FLS_PF_BLOCK_SECTOR_SIZE, FlashCommandSequence);
cycles=10000;
while(cycles--);
unsigned char testdata[] = {0xAA,0xBB,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xBB,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC};

FlashProgram(&flashSSDConfig, flash_prog_address, 40, testdata , FlashCommandSequence);

The forum seems to have some bugs, I posted a reply it appeared then after a while it disappeared, have to post it multiple times to get it on.

While on the topic, can you also let me know how to program more than 160 bytes using this flash driver. There is a method called which is disabled from compiling.

#if FSL_FEATURE_FLS_HAS_PROGRAM_SECTION_CMD

FlashProgramSection

The following code prevents code crashing, however neither the memory is erased or reprogrammed - one of the flash operation still has to be commented out for the other one to succeed

	//returncode = FlashEraseSector(&flashSSDConfig, flash_prog_address, FEATURE_FLS_PF_BLOCK_SECTOR_SIZE, FlashCommandSequence);
		while (0U == (FTFx_FSTAT & FTFx_FSTAT_CCIF_MASK))
		{

		}
		int cycles = 1720000;
		while(cycles--);


	}
	unsigned char testdata[] = {0xDD,0xBB,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xBB,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,0xCC,

With the above code, the code doesn't crash, i.e both the lines executed however NO ERASE and NO WRITE occurs.

Hi 

Could you try waiting for FlashEraseSector to return FTFx_OK? It seems to be caused by too little waiting time.

Best Regards,
Robin

Can you provide me a suitable code for the call back, currently I am passing NULL CALLBACK.

Even otherwise the erasefunction doesn't return if both the functions are present (atleast in the debugger I am not able to get the return value)

 ret = pFlashCommandSequence(pSSDConfig);  <--- the code crashes here doesn't return

/*! @brief Configuration structure flashCfg_0 */
const flash_user_config_t Flash_InitConfig0 = {
		/* for the S32K144 */

		.PFlashBase  = 0x00000000U,
		.PFlashSize  = 0x00080000U,
		.DFlashBase  = 0x10000000U,
		.EERAMBase   = 0x14000000U,
		.CallBack    = NULL_CALLBACK
};

The driver seems to have some bugs, it was much easier to write 5 lines of code to write to internal flash rather than trying to debug these drivers.
