nrf52 flash timeout every second attempt

[goldwake]

Hi all,

I am using a J link to program a NRF52 via keil. It is successful but, every second program it fails with a Flash timeout error.

I am programming the application with S132 already programmed.

Any ideas on why this is and how to solve it?

Under Project Options->Debug-> Settings->Flash Download I have the options Program, verify and, Reset and Run ticked
