Hi There,
I notice the WIP always busy non stop. May I know what happened?
here is my code
#define CMD_S25FLXX_WRITE_ENABLE 0x06 /* write Enable */
#define CMD_S25FLXX_READ_STATUS_REG 0x05 /* read Status Register */
#define CMD_S25FLXX_PAGE_PROGRAM 0x02 /* Page Program */
#define ADDRESS_1 12304

S25FLXX_write_data(ADDRESS_1 ,test_data,7);
S25FLXX_wait_ready();
}

nrf_delay_ms(10);

/* reset transfer done flag */
spi_xfer_done = false;
APP_ERROR_CHECK(nrf_drv_spi_transfer(&S25FLXX, buf_cmd, 1, buf_data, 2));
S25FLXX_spi_wait_until_transfer_is_completed();
printf("buf_data:%d\r\n",buf_data[1]);
}
while ((buf_data[1] & S25FLXX_BUSY) == S25FLXX_BUSY);
}

}
else

}
}
