I've been trying to flash a sample project (GPIOToggle) with Keil uVision 5 using ST-Link Debugger. However, I am getting an error message that reads - No Algorithm found for 08000000H-08000493H.Erase Skipped.Error:Flash Download Failed- "Cortex M3". I've checked and rechecked target options but it just won't work. Using Windows 8. Any help is greatly appreciated.
