Hi there,
I am frustrated while searching the web for an normally easy task - 😒
I am not able to detect, where Boot0 pin is on STLink-v3MODS module Rev.B.
Does anyone know?
I also asked ChatGPT and Google, but this only results in false answers - bricking the device.
Please hlep - Thanks a lot.

Hi,

What you want to do with boot 0 ?

It's for bootloader start, but as the firmware on st-link is not public, you can't do anything useful with boot 0 pin.

That's why you can't find it - it's not there, because useless for this product.

Hi,
I would like to build up a custom ST-Link probe for programming devices via CAN Bus.
Therefore I am looking for a solution to be able to upload custom firmware to the STLink-v3MODS Rev.B.
Help is higly appreciated.
PS: I have seen such a solution - it must be possible in some way.
Here is a similar solution I found in the www.
 

custom STLink-v3MODS Rev.B
USB name “STLINK USB2CAN”

Hi,

I think you are on the wrong way.

Using Boot 0 would allow to flash the st-link with any other stuff, but destroys the st-link functionality.

So what you want - destroy it and use as CAN interface?

Btw a CAN interface is already on the V3 mods, so why you don't just use this and keep the st-link functionality working?

Hi,
yes, thanks, you might be right.
I am trying this already.

Right, use the CAN interface on the v3mods, just add a CAN driver chip as seen on the pic you posted.

And you still have the st-link functionality, for debugging and programming.

That's the way it is intended to be used.
