The compiler will zero initialize alle vaiables/RAM after power on but if the variables is in the protected softdevice memory then it might not work. Not sure if this is the reason but can you check your RAM start and see that it is correct?

Yes. Correct. Why?

So if memory protection is disabled then it works fine?

It seems that m_queue.count = 1 and this flash operation is never performed (m_queue is a module variable in fstorage.c SDK12.3).

My app is not an unmodified example from the SDK but resembles https://github.com/NordicPlayground/nrf51-ble-micro-esb-uart where BLE advertising runs concurrent to a protocol that uses the timeslot feature of the S130.

Hi,

Are you using an unmodified example from the SDK? Have you tried debugging to see where the busy function is coming from? Which fstorage module?
