Question
STM32WB5MMG and USB
Hi,
I'm working with an STM32WB5MMG. I need to use both USB and BLE. I see that there are some threads opened about problems regarding the use of both USB and BLE in the same project due to the HSI48. However, I added LL_HSEM_1StepLock(HSEM, 5) to prevent the CPU2 to disable the HSI48 oscillator when it does not use anymore the RNG IP. It was working until I add all the peripheral. I report my main code.
Someone has suggestion?
Thanks.
int main(void)
{
/* USER CODE BEGIN 1 */
/* USER CODE END 1 */

/* Configure the system clock */
SystemClock_Config();
/* Configure the peripherals common clocks */
PeriphCommonClock_Config();

MX_IPCC_Init();
/* USER CODE BEGIN SysInit */
//NB: to use USB and BLE you must add this line
