Posted on January 09, 2015 at 16:39There's a bug in STM32CubeF3 Rev 1.1.0 ''STM32F3348-Discovery/Examples/HRTIM/HRTIM_BuckBoost'' example, causing the TIMA timer to generate PWM with the wrong frequency. This is due to the TIM1 Compare2 init structu...

Hi Jan,I've tested your sequence, and indeed 1 DMB instruction delay is needed to have the correct result. This is why I prefer to start the counter first to let some time for the update to happen.Anyway, we'll follow your recommendation and better d...

Hi Jan,Sorry... I've corrected the snippets (and indeed there's no need to RMW the EGR register).Thanks and best regards,Vincent@Community member

Hi @Community member,Sorry for this very late answer.... I agree with you, the statement in the user manual only applies if there is an update of the register. And it's for sure missing in the description, we'll have to change this, also adding some...

Hello,I confirm that the correct description in the L475 one:In Center aligned mode, for odd values of RCR, the update event occurs either on the overflow or on the underflow depending on when the RCR register was written and when the counter was lau...

Hello @scaprile ,Thanks for reporting this issue. It is indeed a print error and the Ethernet can work at 180MHz.The table in section 33.4.1 was correct (180MHz) but the register description is not.It'll be fixed for RM0090 next release.For the late...

Re: STM32F429ZI Ethernet @180MHz RM0090 33.8.1 page 1197, ETH_MACMIIAR CR: max value is 100 150-168MHz HCLK/102 Is this a print error (other micros in the family can only reach 168MHz) or the controller is not specified to work at 180MHz ? Thx
