I am currently working on a board designed around the STM32H725RGV6 and have encountered issues with it being recognised by STM32CubeProgrammer as I get the message "target not found" when connecting it to a STLINK-v3-minie. With my previous experien...

Thank you for spotting that. I initially discounted the LDO not being present because of this line in AN5419,"When LDO is available but VDDLDO pin is not present on the package, VDDLDO is internally connected to VDD," but I must've ignored "available...

I'm really leaning towards the fact that I caused some sort of heating damage while soldering the MCU.

@STOne-32 1)I disconnected R10 from ground and connected BOOT0 to 3.3V but there was no change in the voltage at VCAP2) I measured the current as 4.8mA for the entire PCB and the battery has a voltage of 3.83V.3) All VDDx pins are connected to the ou...

By partial PCB do you mean a PCB that doesn't have the STM32 IC soldered?

Thanks for the response. I unfortunately don't have access to an X-Ray inspection machine though the rest of the board has passed an X-Ray inspection. I have made another board in the meantime but it also doesn't work.Could you elaborate on what you ...
