TM_RTC_Config #5

Closed qermit closed 8 years ago

qermit commented 8 years ago

TM_RTC_Config does not set all RCC_PeriphCLKInitTypeDef struct entries. PeriphClockSelection may have random value and HAL_RCCEx_PeriphCLKConfig will hang.

Let me know about yourfix. According to the clock you wanna init, these options are used and other ignored.

Waiting your fix. Have a nice day.

Edit: I have check your "bug" post. As you can see from HAL_RCCEx_PeriphCLKConfig function, it first check for which clock TYPE it goes. If RTCCLK is selected, then it does not use any other types of structure, only these.

I've created pull request #6 I'm not sure if this is correct (works with stm32f429l-discovery).

HAL_RCCEx_PeriphCLKConfig is correct, however nothing is selected in TM_RTC_Config and RCC_PeriphCLKInitTypeDef.PeriphClockSelection has some garbage that was previously in this memory area. So in my case (24-STM32Fxxx_RTC_LCD) RCC_PeriphCLKInitTypeDef.PeriphClockSelection was equal to 1

Yes, true that. I've fixed it, just must upload code.

Thanks for that.
