SPC58EC with Flash driver

Question

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.pdfIn FlashProgram ,size Size, in bytes, of the Flash region to beprogrammed.If size = 0, C55_OK returns.It should be multiple of word and its combination with dest shouldfall in either main array or UTest block.multiple by 8, i think    Best regards               Erwan

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.

https://community.nxp.com/docs/DOC-105380

https://community.nxp.com/docs/DOC-106580

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

Thanks.

Best regards
