Dear all,I am using a NUCLEO-L4R5ZI board and am trying to get the octospi interface running in quad mode.After generating the code I tried to run the generated code in the STM32CubeIDE but failed to debug it. Since it seems that the system memory ge...

I am planing to design a USB interface for programming purposes on STM32H743VIT6 as the bootloader is already integrated on the µC.

I wondering on which hardware configuration, I have to implement for this purpose.Could I just use the differential pair as in joined picture without VBUS (as the µC is supplier on Board)?I would like to get more details on how to design this interfa...

Hello, I am designing my Hadrware base on STM32H743VI. Was looking for Power supply application note I could not find any. I would like to know how I would have to connect my VCAP as the LDO is not used or provided. Shall I put it on 100n??

What about Vref+??As I am not using any Battery, I have decided to connect Vbat directly to VDD, is that correct?OSC32 will not be used in my app, will it be possible for to leave it open?

Resolved! STM32L4A6VGT6P - is the SMPS optional?

I am in the process of designing a new controller for a product and the only processors that seem available in any quantity are the -P versions. The datasheet isn't clear for these if the SMPS is optional and you can just use the internal LDO, or if ...
