Is it possible to ''re-flash'' the ST-Link ?

I have several discovery boards and last week I got a nucleo board. I made a mistake and connected another SWD debugger to STM32F103 SWD pins instead of on-board target microcontroller and erased ST-Link firmware.

Is there any possibility to ''re-flash'' the ST-Link firmware back into the STM32F103?

That probably took a lot of work.

You should perhaps look over the web for people doing home-brew or boot-leg ST-LINK devices, there are definitely binaries out there.

Several possibilities:

1. Flash another debugger on the board:

2. Look for the firmware image of the stlink. At some point it was found on some russian site as written on the page above. The image if for some old version of the STlink-V2, but can be updated.

3. Ask your FAE or some ST-insider for the image.

Thank you both. Instead of programming stlink on the discovery board I made one myself:
