Hello. I always dreamed to have a st-link debugger, because using
stm32discovery for programing other STM32 is not very comfortable (it is
taking too many space on desk and too many ugly wires ). I want to show such
you a useful and cheap thing for stm32 as DIY ST-link V2 if you will make it as
bonus you also will be able to program STM8 microcontrollers. Thanks to
russian resourse http://we.easyelectronics.ru/STM32/sozdaem-st-link-
v2.html now we have a nice detailed guide how to make your own DIY ST-link
V2.
First of all schematic of device.

Now it is time to upload rmware into our device. We will need a usb-uart
adapter, jumper, rmware and “Flash Loader Demonstrator” that you can
download from st.com site.
Connecting adapter’s and board pins “TX” “RX” “GND” as in schematics and
“Boot 0” jumper according image from original article.
Then you need to upload rware with “Flash Loader Demonstrator” .
After what we need to install drivers for st-link .
And in te end of procedure you must run ST-Link upgrate and upgrate the
rware of debugger.
Thats it now you’ve got an DIY ST-link debugger.
And we can program and debug other ST chips.
Then i made a case for it. And glued paper labels.

Hi
First of all thank you very much for that DIY.
I’ve used a breakout board with a STM32F103, ashed the rmware from your
blog (the bin- le) with an existing ST-Link and after reboot the Stm32-Utility
detects the STM as a st-link. ok!
BUT when trying to update to the newest rmware V2.J19.S4 I get an error:
“update error, please ty again”
Any idea ?
Thanx
Thomas

Well did you check schematics is it the same as in your board?
Especially USB part. Quartz frequency is the same? What is the
full name of your MCU.
