NRF_ERROR_INTERNAL in pm_peer_new() with GCC 9.2.0

[Torsten Robitzki]

Hello,

I'm experiencing NRF_ERROR_INTERNAL from a call to pm_peer_new(). While further investigating into this, it turned out, that the p_bonding_data parameter was checkt to be 4 bytes aligned deeper in fds.c / write_enqueue(). According to GCC, the alignment of pm_peer_data_const_t is 2 (this compiles fine):

#include <peer_manager_types.h>

static_assert(alignof(pm_peer_data_bonding_t) == 2);

Is this a problem that only occurs with GCC?

best regards,

Torsten

SDK Version is 16.0.0

Hi,

Since FDS data must be word-aligned. API documentation for pm_peer_new() should state that the input bonding data must be word (4 byte) aligned.
