Can any one say clearly about this problem, i was trying to load the code but i am getting "no cortex m sw device found". Iam using Jtag to load the code
Not sure there is a clear answer, there are a multitude of reasons why things fail.
Device not connected properly Device not powered proplery Device enters low power state Device held in reset by other components on the board User code reconfigures GPIO pins used by debugger Pod expects VTarget voltage to drive buffers Pod needs newer firmware/drivers
