Does what I needed surprisingly simply. I was amazed could use my otg adapter and a st-link tool to erase and flash a new hex file to a chip that now flies a toy drone like it's a professional racing quadcopter! My pc died and this free app helps me to continue my love of tinkering

Works perfectly. Recognised and flashed my STM32F7 discovery board without any hiccups. If you donate remember to restart the app so it unlocks the rest of the MCU :) will spare you frustration of the "premium" MCUs not working! Thanks for an awesome app!!!

It has worked fine 2-3 times after donation and after that it is using error. error Log "failed to find st link v1 by VID:PID Could not link st link device". On home/main page st link is showing connected. Please help me out. I am using st link v2
