Hi,
I'm using FDS instead of pstorage. FDS version is SDK13.0.0. fds_record_update sometimes always returns FDS_ERR_NO_SPACE_IN_FLASH though I call fds_gc after it gets FDS_ERR_NO_SPACE_IN_FLASH every time.
static void fds_evt_handler(fds_evt_t const * const p_fds_evt)
{
if (p_fds_evt->result != FDS_SUCCESS) {
NRF_LOG_RAW_INFO("FDS_FAILURE %d\r\n", p_fds_evt->result);
return;
}
switch (p_fds_evt->id)
{
case FDS_EVT_INIT:
NRF_LOG_RAW_INFO("FDS_EVT_INIT\r\n");
m_fstorage_operating = false;
break;
case FDS_EVT_WRITE:
NRF_LOG_RAW_INFO("FDS_EVT_WRITE\r\n");
m_fstorage_operating = false;
break;
case FDS_EVT_UPDATE:
NRF_LOG_RAW_INFO("FDS_EVT_UPDATE\r\n");
m_fstorage_operating = false;
break;
case FDS_EVT_DEL_RECORD:
NRF_LOG_RAW_INFO("FDS_EVT_DEL_RECORD\r\n");

m_fstorage_operating = false;
break;
case FDS_EVT_GC:
NRF_LOG_RAW_INFO("FDS_EVT_GC\r\n");
m_fstorage_operating = false;
default:
break;
}
NRF_LOG_FLUSH();
}
void sf_fstorage_garbage_collection()
{
ret_code_t ret;
m_fstorage_operating = true;
NRF_LOG_RAW_INFO("sf_fstorage_garbage_collection\r\n");
ret = fds_gc();
if (ret != FDS_SUCCESS) {
NRF_LOG_RAW_INFO("fds_gc error ret %d \r\n", ret);
}
while(m_fstorage_operating) {
uint32_t err_code = sd_app_evt_wait();
app_sched_execute();
APP_ERROR_CHECK(err_code);
}
NRF_LOG_RAW_INFO("fds_gc success \r\n");
NRF_LOG_FLUSH();
}
static void sf_print_fds_stat()
{
fds_stat_t p_stat;
fds_stat(&p_stat);

}
void update_data(void)
{
ret_code_t ret = fds_record_update(p_record_desc, &record);
NRF_LOG_RAW_INFO("update already exist record. %d \r\n", p_record_desc->record_id);
sf_print_fds_stat();
while(ret == FDS_ERR_NO_SPACE_IN_FLASH)
{
NRF_LOG_RAW_INFO("RUN GARBAGE COLLECTION\r\n");
sf_fstorage_garbage_collection();
sf_print_fds_stat();
m_fstorage_operating = true;
ret = fds_record_update(p_record_desc, &record);
sf_print_fds_stat();
}
}
It makes sense to get the error every time, but it gets the error sometimes. Do you know the cause?
[2017/11/16 0:15] add sf_print_fds_stat() function. attach log file.FDS_GC_ERROR3_REPRODUCED.log
