BLUENRG-LPS flashing problem
Hi,
I am starting to work with STEVAL-IDB012V1A. I use Wise-studio version: 1.3.1_R on Linux. I can compile successfully the example "Profiles_Peripheral_with_Library". In the launch configuration I selected CMSIS-DAP. I do hold PUSH1 button while pressing reset before launching the programming. When I click the green arrow to program I get this in the console:

The addresses where the memory write failed are not the same every time. I got it programmed successfully a few times before but now it always fail. Any clue to get out of this?
Thanks,
