Hi all,
I have some problem with the FDS write function.
This is some example codes for my FDS write:
// Global variables
static uint16_t fileID;
static uint16_t recordKey;
static fds_record_t record;
static fds_record_desc_t record_desc;
static fds_record_chunk_t record_chunk;
static fds_flash_record_t flash_record;
static fds_find_token_t ftok;
struct
{
uint16_t variable1[7];
uint16_t variable2;
uint16_t variable3;
uint8_t variable4[7];
uint8_t variable5;
} saveData;
struct
{
uint16_t variable6;
uint8_t variable 7[7];
} saveData2;
// Inside Main( )
fileID = 0x1000;
recordKey = 0x2000;
record_chunk.p_data = &saveData;
record_chunk.length_words = sizeof(saveData)/sizeof(uint32_t);
record.file_id = fileID;
record.key = recordKey;
record.data.p_chunks = &record_chunk;
record.data.num_chunks = 1;
ret = fds_write();
if (ret != FDS_SUCCESS)
{
NRF_LOG_INFO("Write History fail!\r\n");
}
fileID = 0x1000;
recordKey = 0x2001;
record_chunk.p_data = &saveData2;
record_chunk.length_words = sizeof(saveData2)/sizeof(uint32_t);
record.file_id = fileID;
record.key = recordKey;
record.data.p_chunks = &record_chunk;
record.data.num_chunks = 1;
ret = fds_write();
if (ret != FDS_SUCCESS)
{
NRF_LOG_INFO("Write History fail!\r\n");
}
My fds_write function looks like this:
static ret_code_t fds_write(void)
{
ret_code_t ret = fds_record_write(&record_desc, &record);
if (ret != FDS_SUCCESS)
{
return ret;
}
while (write_flag==0);
NRF_LOG_INFO("Writing Record ID = %d \r\n",record_desc.record_id);
return NRF_SUCCESS;
}
The first write is successful but the second write is unsuccessful. Why does this happen?
