Alternative to use sd_flash_page_erase using FDS

[Arepa]

Hi there,

On my project I was working using sd_flash_xxx functions to write the whole flash pages or erase it, so I added peer manager to my project and I had to switch my functions from sd_flash_xxx to FDS, because I was getting hangs on my code when using sd_flash.

Are there a sd_flash_page_erase equivalent using FDS?

How can I select the address to write or erase using FDS functions?

and What is the max number of pages I can use? can I use 40 pages? I was using 40 writing/erasing about 40 flash pages using sd_flash_xxx functions.

Thanks

Hi Hung, I still have problems after I added fstorage the event the fs_evt_handler doesn't triggered after call fs_store/fs_erase. I registered:

static void sys_evt_dispatch(uint32_t sys_evt)
{
    fs_sys_event_handler(sys_evt);
}

and I call inside my Fstorage initilialization:

#define NUM_PAGES 1

void fstorage_initialization(void)
{
	static uint32_t data;
	uint32_t flash_data[4];
	
	FS_REGISTER_CFG(fs_config_t fs_config) =
	{	
	.p_start_addr = (uint32_t*)0x00060000,
    .p_end_addr = (uint32_t*)0x00061000,  			
    .callback = fs_evt_handler,
    .num_pages = NUM_PAGES,
    .priority = 0xFE  					
	};
		
	fs_ret_t ret = fs_init();
	if (ret != FS_SUCCESS)
	{
		NRF_LOG_INFO("fs_init() BSP_INDICATE_FATAL_ERROR \n\r");
	}
}		

after initialized the peer manager

I call fs_erase:

uint32_t Page_erase(uint32_t page_address)
{
	FS_REGISTER_CFG(fs_config_t fs_config) =
	{	
		.p_start_addr = (uint32_t*)page_address ,
		.p_end_addr = NULL, 			
		.callback = fs_evt_handler,
		.num_pages = NUM_PAGES,
		.priority = 0xFE  					
	};

	fs_ret_t ret;
	ret = fs_erase(&fs_config, fs_config.p_start_addr , 1, NULL);
	APP_ERROR_CHECK(ret);
	return ret;
}

my fstorage callback:

static void fs_evt_handler(fs_evt_t const * const evt, fs_ret_t result)
{
	if (result != FS_SUCCESS)
	{
		NRF_LOG_INFO("fs_evt_handlermand FATAL_ERROR \n\r");
	}
	else
	{
		NRF_LOG_INFO("    fstorage command successfully completed   \n\r");
		fs_callback_flag = 0;
	}
}

Are there any additional step in order to make work fstorage? my original project did not have fstorage or FDS
