BOOTING STM32F469

[LucasStartTech]

@STOne-32 , @Peter BENSCH, @Tesla DeLorean 

HI! I have my wiring below and I wonder what is wrong with it. Hope someone can give me some help!! my BOOT0 -> LOW, PDR_ON -> HIGH, BYPASS_REG -> LOW. And I have the following connections to the ST LINK:

NRST - SWDIO - SWCLK - TRACESWO.

Please see my question/response at the end

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.

 

If you're getting connectivity issues in STM32 Cube Programmer, please show that whole screen, along with error message.

I Got this:

(I Have the same values at the pin and at the capacitor)

VCAP2 -> 360mV when I insert the probe, then it drops to 312mV.

VCAP1 -> 480mV.

NRST -> 396mV.

The total drawn read in the power supply is 0.07A.

I took closer pictures, and FYI, NRST goes from the switch (I was unsure what to do with it, so I put a switch to manipulate it.) to the ST-LINK. If any question seems odd, I apologize, this is my first time trying to design a PCB. I am a CS student and therefore I have never worked so close to the hardware before. Thank you!

Sounds like it's not powered up

VCAP should be 1.25V at viability

NRST should be pulled high internally to 3.3V or VDD

Make sure the PIN 1 is correctly orientated, bottom left corner with readable text on the IC, don't confuse with injection relief ports. Picture of the part on the board would be instructive.

BYPASS_REG : LOW

PDR_ON : HIGH

Also... this is my debugger configuration and the error I get:

@Tesla DeLorean I have a little concern about the pin orientation. I know the dot marks the pin1, but I have 3 dots on the MCU, and therefore I assumed the pin 1 would be on the top left, as the top being oriented in a way that I can read the name of the chip. Did I do it upside down?

[Tesla DeLorean]

See image I posted above at same time you posted this.

Picture of yours would also be instructive as to what you've built..

[LucasStartTech]

Oh OMG, mine is upside down then! :face_with_tears_of_joy::face_with_tears_of_joy:

I will, solder it in the right place now. I will let you know how it goes, appreciate it!!!!

@Tesla DeLorean Hey dude! It worked! I got some issues later with the debugger configuration, but I was able to make some lights blink :D. Thank you!
