Hi
I have been able to successfully write using FDS but I'm unable to read back using the same keys. Here are my code snippets:
#define FILE_ID 0x1111
#define REC_START_ID 0x2222
uint32_t rec_count = 0;
static void fds_timer_timeout_handler(void * p_context)
{
fds_record_t record;
fds_record_desc_t record_desc;
fds_record_chunk_t record_chunk;
uint8_t temp[4] = {0,1,2,3};
record_chunk.length_words = 1;
record_chunk.p_data = temp;
record.file_id = FILE_ID;
record.key = REC_START_ID+rec_count;
record.data.p_chunks = &record_chunk;
record.data.num_chunks = 1;
++rec_count;
ret_code_t ret = fds_record_write(&record_desc, &record);
if(ret != FDS_SUCCESS)
{
debug("[FDS] Write record fail, err_code: %d\n", ret);
if(ret == FDS_ERR_NO_SPACE_IN_FLASH)
{
debug("max number of records %d\n", rec_count);
nrf_delay_ms(100000);
}
}
debug("[FDS] Writing Record key %d\n", REC_START_ID+rec_count-1);
if(rec_count == 10)
{
app_timer_stop(m_fds_test_timer);
debug("start reading data\n");
for(int i=0; i<rec_count; i++)
{
fds_flash_record_t flash_record;
fds_record_desc_t read_record_desc;
fds_find_token_t ftok;
debug("[FDS] Looking for record id %d\n", REC_START_ID+i);
ret_code_t err_code = fds_record_find(FILE_ID, REC_START_ID+i, &read_record_desc, &ftok);
if(err_code == FDS_SUCCESS)
{
if(fds_record_open(&read_record_desc, &flash_record) == FDS_SUCCESS)
{
uint8_t * data;
data = (uint8_t *)flash_record.p_data;
debug("[FDS] found record id %d\n", read_record_desc.record_id);
for(int i=0; i<flash_record.p_header->tl.length_words; i++)
{
debug("[FDS] Data is 0x%8x \n", data[i]);
}
}
else
{
debug("[FDS] Opening record failed\n");
}
if(fds_record_close(&read_record_desc) == FDS_SUCCESS)
{
debug("[FDS] Closing record success\n");
}
else
{
debug("[FDS] Closing record failed\n");
}
}
else
{
debug("[FDS] Could not find the record, err_code: %d\n", err_code);
}
}
}
}
static void fds_evt_handler(fds_evt_t const * const p_fds_evt)
{
switch(p_fds_evt->id)
{
case FDS_EVT_INIT:
if(p_fds_evt->result != FDS_SUCCESS)
{
debug("[FDS] Initialization Failed, error: %x\n", p_fds_evt->result);
}
debug("[FDS] Initialization Success\n");
break;
case FDS_EVT_WRITE:
if(p_fds_evt->result != FDS_SUCCESS)
{
debug("[FDS] Write Failed, error: %x\n", p_fds_evt->result);
}
else
{
debug("[FDS] Write Successful and record id is %d\n",p_fds_evt->write.record_id);
}
break;
case FDS_EVT_GC:
break;
case FDS_EVT_DEL_FILE:
debug("[FDS] File deleted successfully\n");
break;
default:
break;
}
}
Thanks in advance :)
[EDIT]
Here is the main file of code main.c
[EDIT]
I've removed the timer but still I'm getting the same problem. I've modified the main.c file to wait till the file is deleted. main.c
Here is my debug output:
start.....
[FDS] Initialization Success
[FDS] Deleting File
[FDS] Writing Record key 8738
[FDS] File deleted successfully
[FDS] Write Successful and record id is 4066 start reading data [FDS] Looking for record id 8738 [FDS] Could not find the record, err_code: 10
