Hello,
I have a custom board based on the nrf5340 and I am attempting to get bluetooth working.
void ble_gatt_start()
{
int err;
LOG_INF("Starting Ble Gatt Server \n");
err = bt_enable(NULL);
if (err) {
LOG_ERR("Bluetooth init failed (err %d)\n", err);
return;
}
bt_conn_cb_register(&connection_callbacks);
/* Pass application callback functions stored in app_callbacks to the MY LBS service */
err = my_custom_characteristics_init(&app_callbacks);
if(err){
LOG_ERR("failed to init Gatt server (err: %d)", err);
return;
}
LOG_INF("Bluetooth initialized\n");
err = bt_le_adv_start(adv_param, ad, ARRAY_SIZE(ad), sd, ARRAY_SIZE(sd));
if (err) {
LOG_ERR("Advertising failed to start (err %d)\n", err);
return;
}
LOG_INF("Advertising successfully started\n");
}
The problem lies in the bluetooth initialization step with bt_enable. When I step through the debugger it fails at:
k_thread_create(&tx_thread_data, tx_thread_stack,
K_KERNEL_STACK_SIZEOF(tx_thread_stack),
hci_tx_thread, NULL, NULL, NULL,
K_PRIO_COOP(CONFIG_BT_HCI_TX_PRIO),
0, K_NO_WAIT);
in the bt_enable routine in hci_core.c. No error happens when I check the RTT and the whole debugger just freezes indefinitely.
/* Give cmd_sem allowing to send first HCI_Reset cmd, the only
* exception is if the controller requests to wait for an
* initial Command Complete for NOP.
*/
if (!IS_ENABLED(CONFIG_BT_WAIT_NOP)) {
k_sem_init(&bt_dev.ncmd_sem, 1, 1);
} else {
k_sem_init(&bt_dev.ncmd_sem, 0, 1);
}
k_fifo_init(&bt_dev.cmd_tx_queue);
/* TX thread */
k_thread_create(&tx_thread_data, tx_thread_stack,
K_KERNEL_STACK_SIZEOF(tx_thread_stack),
hci_tx_thread, NULL, NULL, NULL,
K_PRIO_COOP(CONFIG_BT_HCI_TX_PRIO),
0, K_NO_WAIT);
k_thread_name_set(&tx_thread_data, "BT TX");
What could be the issue?
I am including relevant info from my config and dts files:

I also followed other recommendations from other questions to configure the internal oscillator on the network core by creating a conf file in a child_image folder in my source directory.I had no luck with this as well.
