Pinout to read stm32F103zet6 using ST-LINK

[tomero]

Hi,

I want to know pinout to read flash from CHIP stm32F103zet6 using ST-LINK.

Can someone provide it, im new on STM32 chip.

Thanks.

The pinout of the chip will be in its datasheet.

The pinout of the ST-Link will be in its User Manual.

If the STM32 is already programmed by someone else, it might be read-protected...

Are you familiar with any other microcontroller(s) ?

Here are some getting started tips:

Im very stuck to reading pinout from datasheet, but I try configuration like this:

But still not connected. Btw, I just want to connect it for read flash test.

Is your STM32 on a development board? or a bare chip? If its on a board then tell us about the board like its name and make. Other wise if you are using bare chips, it still need few more connection in order to work. Like there are so many VCC pins but you have connected only one of them. Proper level on RESET and boot pins also required and decoupling capacitors also.

It's all in Table 5:

Note that this is not a genuine ST-Link - it's a clone:

See How to recognize a genuine ST-LINK/V2 versus a cloned one; in particular, this comment.

Double-check that you have the pinout correct for the actual clone you have - as noted in the above comment.

You need to connect:

• SWDIO pin from the ST-Link to the SWDIO pin on the STM32;
• SWCLK pin from the ST-Link to the SWCLK pin on the STM32;
• RST pin from the ST-Link to the NRST pin on the STM32.

Plus 3.3V and GND

As @avinash_elec said, the STM32 needs to be in a functional circuit.

Why do you need to do that?

I hope you're not trying to steal someone's code ... ?
