3. 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 tinkeringIt has worked fine 2-3 times after donation and after that it is using error.

4. Should limit to erasing only the pages requiredI am learning to love products like this one, it My projects alot better,when I have the right toolsUse "stlinkp app" that works well ..this zflasher has problem in connecting and detecting devicePerfect function and great user Interfacedonated for stm32l083rz.

5. Corrupted the flash, managed to recover with a laptop.

6. The app detected mcu but unable to flash.

7. It erases all the sectors of flash.

8. I am using st link v2I donated, it then allowed me to connect but "programmed with some errors".

9. 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!!!Does what I needed surprisingly simply.

10. error Log "failed to find st link v1 by VID:PID Could not link st link device".

11. On home/main page st link is showing connected.
