I am trying to get a stm 32 with a ftdi programmer to work using the arduino IDE. It worked just fine yesterday, but today I get the error
"stm32flash 0.4
Failed to init device"
I then tried using the tutorial to update the drivers and that hasn’t helped either.
I followed the tutorial here https://learn.sparkfun.com/tutorials/ho … rivers/all
Any help would be appreciated
When you plug the FTDI into your computer, does your operating system detect a new COM port?
If it doesn’t try a different USB cable and double check device manager to see if it shows up as an unknown device.
If it DOES, open a terminal program, select the COM port assigned to the FTDI and place a jumper wire between RX and TX. You can verify the FTDI is working by sending text to the COM port and it should echo back on your screen.
