Compatibility with STLINKV3-MINIE

Hi !

And thanks for the great work, i have managed to use the YAB on a STM32H735G-DK successfully, but when trying to use the STLinkUpgrade.jar exec, I got an error code:

Unexpected device ID for ST-Link micro. Don't know how to upgrade.

Would you consider updating the .jar or giving some information on how to do it ?

Hi, sorry, I did not touch the App STLinkUpgrade.jar, it comes from ST software tools. I do not know how to......

Ok understood, I think maybe they changed the encryption of the f3 files ?

Could you tell me about that part ?

I'm not sure what happened on your case. I remember, ST-Link programmer/updater/upgrader, already check the device serial no (ID ?) before flashing the IC. If your st-link not from ST orignal, you have to flash a hacked version bin code first, then the upgrade App will work.

I am currently upgrading my MINIE from its DFU itself so nothing is hacked there.

Apparently they bumped up security, I managed to get more information:

java -jar STLinkUpgrade.jar -force_prog

It seems it is the f3 files authentication, but I don't know what we can do there...

I don't think there will be a fix anytime soon, I am fine to close this issue
