WIth the upgrade to the new SDK, registering the callback handlers has been made more difficult to figure out.
The .sdh_ble_observers, .sdh_soc_observersers sections are created after .text, etc.

Calling like this:
extern "C" {
#define CROWNSTONE_SOC_OBSERVER_PRIO 0
static void crownstone_soc_evt_handler(uint32_t evt_id, void * p_context)
{
// some logging
}
NRF_SDH_SOC_OBSERVER(m_crownstone_soc_observer, CROWNSTONE_SOC_OBSERVER_PRIO, crownstone_soc_evt_handler, NULL);
}
However, no events are generated.
Is there some way I can debug this? Even an example .elf file (using the SDK15) would be useful.
