    S6E1C3 SWD/JTAG Communication Failure

    y.sato_1575591

      My FM0-64L-S6E1C3 board is not able to be controlled by Keil uVision 5.17. Keil shows "SWD/JTAG Communication Failure" in the Debug/Setting/SW Device window. What should I do to solve the problem?

         

      What is strange is that once I could connect and debug the board under the same configuration of Keil. When it was connected successfully, Keil showed "0x0BC11477 ARM CoreSight SW-DP", as shown in the attached image.

         

      Moreover, under the same configuration one board could be connected while another couldn't. Maybe it means something is changed in the board, but what I did is just programming my code into it...
