Hello.
I'm using STEVAL-IDB011V1. 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".
My friend has no problems with that, and we didn't find any differences between our settings.
I also updated the Keil version, and it didn't help.
Thanks.

Could you please try to erase the BlueNRG-355's flash before to load code in Keil?

No. Even when I try to erase it, it writes the same error message.

Solved!
I checked the board very carefully and saw that jumper JP5 was broken, so I replaced it with another that I had spare, and now I can burn through the Keil.
Thanks.
