stlink v3 mini cannot program c031g4u6, Target no device found

[oyalç.1]

i am sorry for creating a lot of post recently but i just can not program my microcontrollers. 

when ever i try to program it i get this:

STMicroelectronics ST-LINK GDB server. Version 7.5.0

Copyright (c) 2023, STMicroelectronics. All rights reserved.

Starting server with the following options:

Persistent Mode : Disabled

Logging Level : 1

Listen Port Number : 61234

Status Refresh Delay : 15s

Verbose Mode : Disabled

SWD Debug : Enabled

InitWhile : Enabled

Target no device found

Error in initializing ST-LINK device.

Reason: No device found on target.

i have a stlink v3 mini and 3 stm32c031g4u6 microcontrollers soldered to proper breakout boards.

i have SWD interface soldered from the edge connector because i had no luck with cn4. 

SWDIO, SWCLK and RESET are connected. i also have an led soldered to power pins to be sure its powered.

i am sure of the soldering job.

on my first post someone recommeded i solder capasitors so i did that still no result.

i am using linux mint's latest and the code i am trying to upload is just empty machine generated code

here are the pics:

 

  

i made a breakout for cn4:

  sorry for the bad solder job 

thanks for help

The VDD from the AM1117 needs to go to the CN2.10 / T_VCC pin on the ST-LINK-V3MINIE

STM32 Cube Programmer should be able to report the board voltage

The T_VCC is there to power the buffers between the ST-LINK and the Target MCU, say for systems running at 1.8V, 2.7V or whatever

I just want to point out that the very first bullet in the very first reply to your previous thread was to check part orientation along with where pin 1 relative to the text, which you didn't check or at least didn't notice/fix until it was pointed out here.

Perhaps slow down. If you do things correctly, you only need to do them once.

Wiring still looks wrong if the IC is still rotated 90 degrees or 7 pins

Draw a chart, probe continuity and confirm where pin 1 exits

Newer thoughts..

it reads 3,25 Volts. fixed the wiring still nothing.

any ideas on what am i doing wrong?

[Tesla DeLorean]

No

The adapter is quite confusing in it's pin numbering. I've marked Pin 1 on the STM32 you've placed

i am thankful for all the help. i have checked it and you look correct.

i am sorry for creating a duplicate question. i tought pin1 started from the writings beginning not the dot.  i am new to stm32's and i have nobody i can ask except you guys

vdd is +3,3v and vss is gnd correct?

i have managed to narrow the issue to my stlink v3 minie. i went and bought a new stlink v2 mini and it works with cubeprogrammer with the current correct wiring. it appears that i have either fried the v3 mini or dont know how to use it. either way cubeprogrammer and V2 clone works for now
