NFC can't work with freertos in SKD15.3.0

Hi,

I add NFC to my project with freertos. The initialization of nfc is ok. After running few seconds ,it hang. If I comment the usr_nfc_init() that in the main() function, the project runs good.

I don't know why.

Can the NFC  work with freertos? 

My SDK is nRF5 SDK 15.3.0. And my ic is nRF52840. 

void usr_nfc_init(void) {

  ret_code_t err_code;

  /* Set up FIFOs for data that are transfered over NFC */

  err_code = nfc_fifos_init();

  APP_ERROR_CHECK(err_code);

  /* Set up NFC */

  err_code = nfc_t4t_setup(nfc_callback, NULL);

  APP_ERROR_CHECK(err_code);

  /* Start sensing NFC field */

  err_code = nfc_t4t_emulation_start();

  APP_ERROR_CHECK(err_code);

}

My project use esb. And I find that if I use ble, the NFC can work. 

So is there any suggestion when use esb and NFC with freertos?

----------------------------------------------------------------

BLE:

  ble_stack_init();

  gap_params_init();

  gatt_init();

  services_init();

  advertising_init();

  conn_params_init();

  // Start advertise

  advertising_start();

------------------------------------------------------------------

ESB:

// Initialize
clocks_start();
err_code = esb_init();
APP_ERROR_CHECK(err_code);
