hi,
i able to write and read unsigned integer value from the flash, but when i try to write some string to it ,the device is not responding.
void Reading_the_data_from_flash(void)
{
static char rec_data;
nrf_fstorage_read(&fstorage,0x3e000, &READ_BAUDRATE_FLASH, sizeof(READ_BAUDRATE_FLASH));
NRF_UART_TASK_STARTTX;
nrf_gpio_pin_set(TX_D);
printf("Configured BaudRate Reading From Flash is \"%d\" \n",READ_BAUDRATE_FLASH);
wait_for_flash_ready(&fstorage);
NRF_LOG_INFO("Done.");
nrf_fstorage_read(&fstorage,0x3f000, &READ_MSGINTRVL_FROM_FLASH, sizeof(READ_MSGINTRVL_FROM_FLASH));
NRF_UART_TASK_STARTTX;
nrf_gpio_pin_set(TX_D);
printf("Configured MsgInterval Reading From Flash is \"%d\" \n",READ_MSGINTRVL_FROM_FLASH);
wait_for_flash_ready(&fstorage);
