Can't load code on STEVAL-IDB011V2 with Keil. SWD/JTAG Communication Failure.

[AT4]

Hello,

 

I'm using STEVAL-IDB011V2. From the BlueNRG-LP Navigator, I can load the examples on the board. But when I'm using the Keil, it says "SWD/JTAG Communication Failure".

On the options for target in the tab "Device" the device is BlueNRG-355, and the Software Pack is "Keil.STBlueNRG-LP_DFP.2.0.0". In the tab "Debug" it uses "CMSIS-DAP Debugger".

Cannot erase the code either. Jumpers J3-J5 are all in place and not faulty.

SW device error. Not sure what else to try. Thanks heaps
