BlueNRG: BLE Initialization Never Leaves hci_init()
Hello,
I am creating a Bluetooth app on a custom board. I used the same hardware design as the X-NULCEO-IDB05A2 expansion board, but with the sole difference being that the Bluetooth module I'm using is the BLUENRG-M0L instead of the BLUENRG-M0A (which, to my understanding, is just an internal power supply difference and that is it).
I used the SensorBLEDemo project as the base for my code, then brought it up on a separate project to ensure it worked as intended (and it does). However, when I ran the same code on my custom board, the BlueNRG initialization code acts strangely. When the function hci_init() is called, it never leaves the function and, seemingly, gets stuck there.
I call for the BlueNRG initialization in my main.c. I've attached my initialization code below. I get stuck on Line 29. I'm unsure where to look to diagnose this, since this is a HCI premade code. Can anyone help me diagnose this?

}EDIT:
I also did a side-by-side comparison via the debugger in the hci_tl.c file. The hci_init() function is below. In my custom board, my code never goes past line 25 (if (hciContext.io.Reset) hciContext.io.Reset();).
In the Nucleo board, it does go past that line without issue.
void hci_init(void(* UserEvtRx)(void* pData), void* pConf)
{
uint8_t index;
if(UserEvtRx != NULL)
{
hciContext.UserEvtRx = UserEvtRx;
}
/* Initialize list heads of ready and free hci data packet queues */
list_init_head(&hciReadPktPool);
list_init_head(&hciReadPktRxQueue);
/* Initialize TL BLE layer */
hci_tl_lowlevel_init();
/* Initialize the queue of free hci data packets */
for (index = 0; index < HCI_READ_PACKET_NUM_MAX; index++)
{
list_insert_tail(&hciReadPktPool, (tListNode *)&hciReadPacketBuffer[index]);
}
/* Initialize low level driver */
if (hciContext.io.Init) hciContext.io.Init(NULL);
if (hciContext.io.Reset) hciContext.io.Reset();
}
