Hi,
We have been using the STM32WLE5CB for a while now, using the older die revision Z. Since we have a new batch with the new revision Y die of the STM32WLE5x we couldn't get our firmware working anymore.
To try make it work we have tried to use the example LoRaWAN endnode and couldn't get it working on this revision. It seems to get stuck in initializing the RTC Alarm in the MX_NVIC_Init()
HAL_NVIC_EnableIRQ(RTC_Alarm_IRQn);
Where it finally crashes in the core_cm4.h
/**
\brief Get Interrupt Enable status
\details Returns a device specific interrupt enable status from the NVIC interrupt controller.
\param [in] IRQn Device specific interrupt number.
\return 0 Interrupt is not enabled.
\return 1 Interrupt is enabled.
\note IRQn must not be negative.
*/
__STATIC_INLINE uint32_t __NVIC_GetEnableIRQ(IRQn_Type IRQn)
{
if ((int32_t)(IRQn) >= 0)
{
return((uint32_t)(((NVIC->ISER[(((uint32_t)IRQn) >> 5UL)] & (1UL << (((uint32_t)IRQn) & 0x1FUL))) != 0UL) ? 1UL : 0UL));
}
else
{
return(0U);
}
}
Does anyone know what difference there is between Revision Z and Y, and how I can resolve my problem? The 32kHz RTC clock is working on my board where I have looked at the LSCO Clock Output on a scope.
