Just trying to upload blink and I’m getting the error below. The board was used before I purchased it, and seems to have blink already uploaded. I’m not sure what’s causing the error. I’ve got the manufacturer’s cable, so I know it’s not that.
ERROR: Could not determine the JLink serial number of the device corresponding to serial port ‘COM3’, which reports serial number ‘DN028LW5A’.
