STM32F3 fail to download to flash

Andres Rodriguez

Hi, I'm new with Keil software so in advance please be patient with me.

After all software installation I decided to test a demo code in my STM32f3discovery board, but... at the moment on clicking Flash-> Download, it appears a screen saying: "No target connected" followed by another screen displaying: "Error: Flash Download failed - Target DLL has been cancelled"

Any ideas on how to fix this issue?

Note: I already went into configuring flash tools and selecting ST-Link Debugger on Utilities and Debug tab, but no results still.

Thanks for your time
