Hi there,this is an general question.Every serious engineer walks thru errata document as it gets published.So do I now.Do I have to review every HAL / LL function which may coincide with erratic behaviour?Is proposed in errata workaround already imp...

Hallo,for security reason I have to stop HRTIM generating 3-phase signal for PMSM motor.It works as described in RM0433 (37.3.23) with DBG_HRTIM_STOP = 1: when debugger stops MCU predefined "FaultLevel" appears on outputs as expected. HRTIM goes into...

Hallo, I have to use shadow registers (PREEN=1) in HRTIM slave timers. I have decided to use following configuration: UPDGAT = 0110: the update occurs on the update event following a rising edge of HRTIM update enable input 1 (hrtim_upd_en1) to perfe...

Hallo,until now we have used STLINK-V3SET connected with MIPI10 to custom evaluation board based on STM32H743.For next custom board we need cost efficient debugger solution, just like STLINK-V3MODSBut it seems not to work together.MIPI10 connector us...

Hallo,I want to update MASTER CMP1 over DMA and the others TIM_x on MASTER-update.New values of CMPx registry are calculated in SysTick_Handler() and should be updated at once.The problem is: MASTER update on DMA does not work.Could anyone please loo...

Thank you, Pierre, yes, that is the easiest way using TxSWU.You have expresed here very clearly "update event" and "update request". This helps a lot to understand the logic behind. In RM it is not so obvious. Thanks a lot for this disambiguation.How...

My debuger is MB1467B and looks like V3MINI but it is detected as V3MODS:Log from CubeProgrammer: 10:52:22 : STM32CubeProgrammer API v2.14.0 | Windows-64Bits 10:53:18 : UR connection mode is defined with the HWrst reset mode 10:53:18 : ST-LINK ...

It seems, I have found solution.The line:pTimerCfg.UpdateGating = HRTIM_UPDATEGATING_DMABURST_UPDATE;cannot be set inside CubeMX, but it works as I expect. TIMER_A .. C are updated only when MASTER.CMP gets update over DMA. Kind Greetings

Hallo Pierre,mentioned function HAL_HRTIM_BurstDMAConfig() is already called inside CubeMX generated initialization code, i.e. inside "static void MX_HRTIM_Init(void)". And there is no issue. Yes, I use USE_FULL_ASSERT and I get no error. The functio...

Hello Pierre,it sounds good for me. I'm just trying to impement it with HAL library. Not an easy task. Is there maybe example code based on HAL functions? Best Regards

Can the rising signal 'hrtim_upd_en1' come directly from software?
