100khz Oscillator for LSE input. The OSCillator works right bcz I test the waveform by scope.but stm32h7b0vb cannot get lserdy bit set.Seems I m the 1st Person meet the situation.plz help me. Thanks.

condition 1. Start the STM32CubeIDE directly by mouse.(in windows 10 os)condition 2. Open the CubeMX software. Choose one project & click Code Generation. And wait for it finished then Click "open project" button. then the Stm32CubeIDE A.K.A eclipse ...

STMCUBE IDE live expressions bug? or it is just cannot be that

kgai · 2022-08-15

no, the problem still exist.new info: I change the Oscillator to 32.768Khz and it works well.so conclusion is the STM32H7B0 LSE cannot use freq other than 32k768. the datasheet is wrong about it.

I fix the problem. THANKSthe Reason is I must call LL_RCC_SelectDigitalClock after EnableBypass.now work well.

who can help me? IS this the bug of stm32?

kgai · 2022-08-11

Thank u anyway!but things are not that simple. Look at the pic below. I will explain it.the "ready logic" module inside the red circle is very important, bcz follow it there is an "AND" gate, while the "ready logic" or "LSERDY Bit" output 0 then we w...

Thank u first!it is sure Oscillator , Not crystal. I set the bypassI guess it is bcz ST not test LSE by freq other than 32768hz. I also try call the function LL_RCC_LSE_SelectDigitalClock() but no effectI will check the link u mentioned from now....

I use 100Khz oscillator for LSE on STM32H7B0VBT6 but LSERDY cannot work

The font perfomance far more better when: I start the STM32CubeIDE in CubeMX software. whats the reason?

In fact there IS A BUG during stm32l496 + TouchGFX(4.15, Freertos & No dma mode)

stm32cube IDE live expressions can be displayed periodicity but cannot be written any time
