Boot standalone STM32F469IIT6

[LucasStartTech]

Hi! I am new in electronics, but I am trying to design my PCB using STM32F469IIT6. I did a similar project before using a simple atmega168, but the STM32 seems way more complex. I wonder what the minimum of hardware connection is I need to be able to BOOT or even detect the target using my ST-LINK. Right now, I powered all VDD pins and VDDA pins, as well connected all the GND pins. I set up pins 137-SWCLK and 128-SWDIO in my IDE, connected the ST-LINK, but it does not find the target. I wish someone could give me a help.

 

Thank you!

Dear @LucasStartTech ,

 

Welcome in our Community , Herr is a link for the minimum hardware setup required for STM32F4 series : https://www.st.com/resource/en/application_note/an4488-getting-started-with-stm32f4xxxx-mcu-hardware-development-stmicroelectronics.pdf

 And below for F469 MCU :

To better help , if you can provide schematics around all power and dedicated pins in particular PDR_On, Bypass_Reg and VCAPxx pins .

let us know ,

Cheers,

Hi! I've been following the diagrams, they really help! I bought an adapter, where I then soldered the MCU to be able to kind of work in the breadboard. I wired the pins in the diagram, but the ST-link did not find the target. I also got another ST-LINK as Peter suggested, and I thinking in manufacture one version, for I am wondering if the distance of the capacitors from the VDD pins are one of the reasons for my constant failure. I will post the schematic I have so far. Thank you very much!

@LucasStartTech And please don't try any of these ST-Links in colourful tin cans, because they are all fakes and don’t get recognized by the STM32CubeIDE. Instead, use an original ST-Link from a trustworthy retailer (i.e. not Alibaba or similar) so that the connection can be established.

Good luck!

Thank you, Peter! I got both ST-LINKS, but I've only tried the cheap one. I will port the schematic and also, I will try the other ST-LINK.

 

Thank you!!

Check part orientation

Check voltage present on VCAP pin, and capacitors

Check voltage observed on NRST pin

Provide a schematic, constrained to the STM32 if that's simpler, so we can better understand what you've built.

A large, clear and in-focus picture of the board with the part in-situ will also be illustrative.

The ST-LINK expects to see a target voltage on pin 1 or 2 of the standard JTAG 20-pin connector.

Sounds like an orientation issue
