ST-link utility v. 4.0 and STM32CubeMX v.4.20 Bug

[antonioB]

Posted on April 04, 2017 at 09:54

hi to all, i update the firmware of my  the my stm nucleo L152RE with st-link to the version

'ST-link firmware update V2.J27.M15 STM32 Debug+Mass storage'  and

later i update STM32CubeMX to 4.20 version

i use the cube mx to configure the gpio, when i configure RCC and RTC i see that the system crashes

i see the compiler crashes when arrived in this point

 if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)

  {    Error_Handler();  }

the system go in Error_Handler();

I use old example, i created it one month ago, i don't open CubeMX i use only IAR for open the project but

now this example don't work and i see the compiler crashes when arrived in this point:

 if (HAL_RTC_Init(&hrtc) != HAL_OK)

  {    Error_Handler();  }

the system go in Error_Handler();

if i use old firmware, ST-link firmware update V2.J20.M4 STM32 Debug+Mass storage my old example work well.

excuse me for my bad english

best regards

Antonio

Hi

Buonanno.Antonio

,

This is confirmed bug in RCC clock configuration with

CubeMx 4.20 and will be fixed soon

in the new patch release.

The issue occurred due to this error line:

RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_HSE;

and y

ou should replace it

with the following line that will resolve your problem:

RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE;

Please try this update then let me if this resolve your problem.

We apologize for any inconvenience this may cause.

Hi Imen thanks for your answer but i have this configuretion code from CubeMX:

RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_LSE;

when i use the  code that you posted it , i see the equal problem

Hi

Buonanno.Antonio

,

In your case, you should removethe oscillator that you don't need

RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_***;

thanks, now work only if you select, in  cubemx, the CSS ENABLED in RTC/LCD Source Mux  and  in SYSTEM clock Mux

Hello Antonio,

Great thanks for your inputs.

CubeMX4.20 has a regression in the clock generation code, that pass through all validation tests.

The behave is exactly what you have reported.

This has been corrected in CubeMXv4.20.1.

I advise you to upgrade to that version, and create a new project.

Kind regards
