Creating a st-link programmer

Hi,

I would like to use a STM32F103 micro as a st-link programmer on my board to program or debug another micro using USB (like the one on STM32F4 Discovery board). Is it possible to download the st-link firmware to a micro like that? If possible, how should I do that?

Thanks in advance.

No. ST does not publish the bootloader which is in the STLink.

Not only that, it is secured inside chip, so you can't read it with another ST-link.

My solution, expensive, but de-solder chip and solder in your board, it works, sometimes even if you need MCU in LQFP package, it can be cheaper too

in theory you can get hex file than you are upgrading firmware in DFU mode in stlink utility, just need a lot of work in order to extract data, it i possible, but tricky.

Either ask your FAE about a solution or have a look at the the blackmagic debug probe
