PROBLEM WHILE READ FLASH 25Q64 USING SPI FOR NRF52832 .

[NghiHH]

I wanna ask about this code. Why we use "memset" before read flash?. Must i create new token before read flash.

#define RECORD_KEY 0x2222

fds_flash_record_t flash_record;

fds_record_desc_t record_desc;

fds_find_token_t ftok;

/* It is required to zero the token before first use. */

memset(&ftok, 0x00, sizeof(fds_find_token_t));

/* Loop until all records with the given key and file ID have been found. */

while (fds_record_find(FILE_ID, RECORD_KEY, &record_desc, &ftok) == FDS_SUCCESS)

{

if (fds_record_open(&record_desc, &flash_record) != FDS_SUCCESS)

{

/* Handle error. */

}

/* Access the record through the flash_record structure. */

/* Close the record when done. */

if (fds_record_close(&record_desc) != FDS_SUCCESS)

{

/* Handle error. */

}

}

Hi

I'm not sure which SDK version you're using exactly, but yes, you need to zero the token before reusing it like the comment right above the memset() call says.

Best regards,

Can use tell me why "need to zero the token before reusing it". Token for what ?
