Flash example for s32k116

AbhiMR — Tue, 17 Dec 2024 05:57:58 GMT

Hi NXP ,

In ld file i need to define section as below,

MEMORY
{
/* Flash */
m_interrupts (RX) : ORIGIN = 0x00000000, LENGTH = 0x000000C0
m_flash_config (RX) : ORIGIN = 0x00000400, LENGTH = 0x00000010
m_text (RX) : ORIGIN = 0x00000410, LENGTH = 0x0001F7E0
m_layout1 (RX) : ORIGIN = 0x0001FBF0, LENGTH = 0x00000400
m_layout2 (RX) : ORIGIN = 0x0001FFF0, LENGTH = 0x00000000

}

after which I started using flashdriver.c and .h file .

FLASH_DRV_Init()

/* For erase */

ret = FLASH_DRV_EraseSector(&flashSSDConfig, u32Address, BLOCK_SIZE);
DEV_ASSERT(STATUS_SUCCESS == ret);

/* Write data which are of 4 bytes minimum */
ret = FLASH_DRV_Program(&flashSSDConfig, u32Address, MAL_MEM_FLASH_SECTOR_SIZE, u16Data);
DEV_ASSERT(STATUS_SUCCESS == ret);

/* read */

memcpy(store , linkarray, size );

In my code it will work only few time and not consistent with memcpy.

what will be the way to write properly , what are all we need to do config intially ?

Do we have any read function other than memcpy ?

Could you please help with better example for this usage ?

Hi @AbhiMR,

I'm not sure I understand the issue here.

You can refer to the S32K1xx RTD drivers.

There is Ftfc_Mem_InFls_Ip_Read() in Ftfc_Mem_InFls_Ip.c

The flash can be read through a pointer, simply like this:

for(uint32_t i = 0; i < size; i++){ read_buffer[i] = *((volatile uint8_t *)(address + i)); }

Check the memory with the debugger after each write.

Regards,

Daniel

extern const flash_user_config_t Flash_InitConfig0;
/* Flash user configuration 0 */
const flash_user_config_t Flash_InitConfig =
{
/*.PFlashBase = 0x0001FBF0U,
.PFlashSize = 0x0001FBF0U,
.DFlashBase = 0x1FFFFC00U,
.EERAMBase = 0x20000000U,
.CallBack = NULL_CALLBACK
*/
.PFlashBase = 0,
.PFlashSize = 0x20000U,
.DFlashBase = 0x0001FFF0U,
.EERAMBase = 0x20000000U,
.CallBack = NULL_CALLBACK
};
How to configure this? I f I change, erase will fail. Can you please provide me an example I can be able to read write above designed layout. Or how i can customise and use in s32k116 please let me know?

Basically i need to do read, write and earse operation on this
m_layout1 (RX) : ORIGIN = 0x0001FBF0, LENGTH = 0x00000400
m_layout2 (RX) : ORIGIN = 0x0001FFF0, LENGTH = 0x00000000

Hello @AbhiMR,

Where did you get the Flash_InitConfig and the flashdriver.c and .h files? It does not mach the S32K116 memory map (S32K1xx_Memory_Map.xlsx attached to the Reference Manual).

Please use either the S32DS 3.4 IDE with the SDK drivers, or preferably the S32DS3.5 IDE with the RTD drivers.

There is a GUI that allows you to configure the structures such as Flash_InitConfig.

Regards,

Daniel

Its hitting Device assert.

In this I want to explore how to use dflash

Hello @AbhiMR,

If you generated the SDK code in S32DS 3.4 with SDK 4.0.3 installed, you would get this structure

/* Flash user configuration 0 */ const flash_user_config_t Flash_InitConfig0 = { .PFlashBase = 0x0U, .PFlashSize = 0x20000U, .DFlashBase = 0x10000000U, .EERAMBase = 0x14000000U, .CallBack = NULL_CALLBACK };

in .../board/peripherals_flash_FTFC.c

Not this:

const flash_user_config_t Flash_InitConfig = { /*.PFlashBase = 0x0001FBF0U, .PFlashSize = 0x0001FBF0U, .DFlashBase = 0x1FFFFC00U, .EERAMBase = 0x20000000U, .CallBack = NULL_CALLBACK */ .PFlashBase = 0, .PFlashSize = 0x20000U, .DFlashBase = 0x0001FFF0U, .EERAMBase = 0x20000000U, .CallBack = NULL_CALLBACK };

You need to:

Install S32DS 3.4
Install SDK 4.0.3
Create flash_partitioning_s32k116 from example
Generate the SDK configuration:
