Hello,This question has been asked several times but I have to raise it again since no solid answer so far and I am stuck!My configurations:stm32h745ZI-Q Nucleo-144 board. CubeMx ver5.6.1CubeIDE ver1.4.1lwip 2.1.2 with mqtt clientfreeRTOS 10.2.1Why i...

Sorry this is a very simple question but somehow LED LD2 just won't work on STM32h745ZI-Q nucleo 144 boards. As per the manual "UM2408 STM32H7 Nucleo-144 boards", the LD2 is connected to PE1 (by the way, I tried PB7 as well as the older one may on th...

I have finally figure out the quirks why cubeMX not allows to change the NO_SYS option for STM32H745 (maybe others as well). It may have a reason but hope STM can improve or at least explain clearly.If System Core -> CORTEX_M7 -> CPU DCache is disabl...

OK, on the Nucleo-144 board, the Vref is hardwired via the R39 resister to the VDD_MCU. With this, the Vref for both ADC/DAC is fixed. Removing (un-soldering) the R39 from the board got it working as expected.It would be nice if the cubeMX can provi...

Hi @Khouloud ZEMMELI ,I am using stm32h745zi-q Nucleo-144 board and facing similar problem. When selecting internal voltage reference scale as SCALE 1: around 2.048V in cube mx (6.0.1), it does set the clock but still seem to generate the wrong code...

Thanks Piranha. I don't know what went wrong with my CubeMX. It is version 5.6.1 whilst the embedded in CubeIDE is 6.0.0. Both the same. Even when I build a project from scratch, those options are still greyed out. No idea!Anyway, since I am using mq...

OK, after some diggings, link https://community.st.com/s/question/0D50X0000BOtfhnSQB/how-to-make-ethernet-and-lwip-working-on-stm32 and its links to other articles explain some hints thanks to @Piranha 's post.So to date, stm32cubeMX cannot use NO_S...
