SPC58EC with Flash driver

[otcagon]

Hello, I am currently struggline with flash program with some tools.

The tool send 62byte data with CAN FD and I want to write down it.

I am using SPC5Studio with Flash_driver (ssd_c55.h)

* FILE NAME : ssd_c55.h *
* DATE : December 19, 2011 *
* AUTHOR : FPT Team

and the function exported.

extern UINT32 FlashProgram ( PSSD_CONFIG pSSDConfig,
     BOOL factoryPgmFlag,
     UINT32 dest,
     UINT32 size,
    UINT32 source,
    PCONTEXT_DATA pCtxData
);

I modify  the eeprom_lld.c as bleow for programming the software. I checked that the len=8U works. (8U is defined in examples.)

If the len is set to 6, it is not work. in case of 4 then it is partly works. (4byte date programmed and 4bytes are skipped). Are there any way to write down the data with variable length?

uint32_t eeprom_lld_flashprogram(uint32_t address, uint64_t buffer, uint32_t len) {
   uint32_t returnvalue;
   uint32_t bufferpointer;
   uint32_t result;
   CONTEXT_DATA pgmCtxData;

   bufferpointer = (uint32_t)(&buffer);

   returnvalue = FlashProgram(&ssdConfig, FALSE, address, len, bufferpointer, &pgmCtxData);
   if (C55_OK == returnvalue) {
   /* Call FlashCheckStatus() to check status of the progress */
   while (C55_INPROGRESS == FlashCheckStatus(&ssdConfig, C55_MODE_OP_PROGRAM, &result, &pgmCtxData)) {
  }

   if (C55_OK != result) {
   return FLASH_ERROR_PROGRAM;
   }

}
else {
return FLASH_ERROR_PROGRAM;
}

(void)buffer;
return FLASH_OK;
}

Hello ,

cf UM2636.pdf

In FlashProgram ,

size Size, in bytes, of the Flash region to be
programmed.
If size = 0, C55_OK returns.
It should be multiple of word and its combination with dest should
fall in either main array or UTest block.

multiple by 8, i think

    Best regards

Hello Erwan

 

Thanks for the reply, I tested with several value and it works with multiple of 8.

It does not work with multiple of 4.

Are there any source code avalable for the flash driver.

When I check the item from internet, I find following two document

it do not shows the full code.

I am not sure are there any code with C file or  not. 

Thanks.

Sorry Joonseok ,

we have only the library in SPC5Studio Tools Suite.

SPC56/57/58 shoudl have the same flash driver as MPC56/57
