Hi there,With STM32CubeIDE v. 1.18.0 there comes new GNU tool ver. 13.3My linker script defines between others: RAM_D3 (xrw) : ORIGIN = 0x38000000, LENGTH = 64K This area is used explicitely for BDMA /* RAM D3 f...

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...

Thank you for quick reaction.Below I enclosed minimalistic project causing linker issue.Results when changing GNU Tools are suspicious:GNU Tools 13.3.rel1.ramd2 0x2400057c 0x80 load address 0x0801a4f8.ramd2 0x2400057c 0x80 ./Core/Src/main.o0x2400057c...

Hi Pavel,thank you for advice.Yes, I have already installed old toolchain (12.3) and set it as DEFAULT but have no chance to choose newlib version.Newlib version seems to be hardwired with toolchain release.No option to change, GNU 12.3 corresponds t...

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

Linker issue with GNU Tools 13.3

MCU Errata vs HAL, LL

HRTIM restart after DEBUG

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

STLINK-V3MODS can't work with STM32H7
