Hello, I am trying to flash a simple code of led blinking on stm32vl discovery. The code is compiling but there is a problem in flashing the code on board. It is giving the error flash timeout:reset the target and try again,error:flash download failed-"cortex M3". Please help me with this.
Make sure to select the suitable ST-LINK options, including using SWD mode, and not JTAG
Other options would be "Connect under Reset". If you continue to have problems try using the ST-LINK Utilities, and make sure the firmware and drivers are current.
If you break the GPIO pins, or put the device into a low power mode, you can pull the BOOT pin high so it doesn't run flash based code.
