Hi dear support people,floating CMOS inputs in general pose both serious hardware and software problems, as we all are quite aware of.Regardless, the D- line of the STM32H7 USB FS PHY (used as a USB device role) is floating, when the host USB cable i...

Hello dear people,Of course, the reason is that Get_SerialNum () tries to read the device ID (UID_BASE), which unfortunately is not supported in CM4 core. So i get a Hard Fault.I do have a solution getting the UID from the CM7 core, but alas, it's qu...

According to the STM32H747xI/G datasheet, the STM32H747IG has a VCAPDSI pin, but no VDDDSI pin at all.I'm sure i get something wrong here, because without VDDDSI pin, the VCAPDSI pin would be a miraculous source of energy! But seriously: do i have t...

Hello,i'd like to add, that i get the same problem (lots of "pattern recipe did not update peer target" from the build output, CubeIDE 1.14.0, STM32G474), but for a different reason (not using "-flto).I use "-Wswitch-enum" for the whole project, but ...

Thanks for your answer.Unfortunately, none of it answeres my questions.These are my questions:Can anyone tell me how to change the Cube template in that way?Any better solutions to fix this?

How i'm happy. Thank you very much!BR, Albert

Hi Imen,thank you for you nice response. The DSI regulator makes more sense to me now.Just to clarify:I guess, it's not the VCAPDSI pin that is internally directly connected to some VDD pin,but to be precise, it's the non-external VDDDSI signal that ...

Internal USB FS PHY data lines sometimes are floating inputs. - Solution?

Get_SerialNum () crashes when USB middleware is used in STM32H7 CM4 core. - Workaround?

There seem to be a mismatch in the STM32H747 documentation: The 176 pin version should have an VDDDSI pin, but it's missing in the pin definition and in the pinout. Is it a typo?
