RE: Running the SES v4.12 debugger on nRF5_SDK_15.3.0_69ac345 crashes

Hi Kishan,

Error 0x86 = NRF_ERROR_STORAGE_FULL. I don't think it's good idea to "force" it to 0x00 (and you can't).

When the storage is full you need to free it up by calling garbage collection (fds_gc), you may want to check what's the flash space you defined and how much you data you plan to store.

Some more details:

The error occurs when pds_init() is executed from peerManagerInit():

ret_code_t pm_init(void)
{
ret_code_t err_code;

err_code = pds_init();
if (err_code != NRF_SUCCESS)
{
NRF_LOG_ERROR("%s failed because pds_init() returned %s.", __func__, nrf_strerror_get(err_code));
return NRF_ERROR_INTERNAL;
}

err_code = pdb_init();
if (err_code != NRF_SUCCESS)
{
NRF_LOG_ERROR("%s failed because pdb_init() returned %s.", __func__, nrf_strerror_get(err_code));
return NRF_ERROR_INTERNAL;
}

err_code = sm_init();
if (err_code != NRF_SUCCESS)
{
NRF_LOG_ERROR("%s failed because sm_init() returned %s.", __func__, nrf_strerror_get(err_code));
return NRF_ERROR_INTERNAL;
}

err_code = smd_init();
if (err_code != NRF_SUCCESS)
{
NRF_LOG_ERROR("%s failed because smd_init() returned %s.", __func__, nrf_strerror_get(err_code));
return NRF_ERROR_INTERNAL;
}

err_code = gcm_init();
if (err_code != NRF_SUCCESS)
{
NRF_LOG_ERROR("%s failed because gcm_init() returned %s.", __func__, nrf_strerror_get(err_code));
return NRF_ERROR_INTERNAL;
}

err_code = gscm_init();
if (err_code != NRF_SUCCESS)
{
NRF_LOG_ERROR("%s failed because gscm_init() returned %s.", __func__, nrf_strerror_get(err_code));
return NRF_ERROR_INTERNAL;
}

internal_state_reset();

m_peer_rank_initialized = false;
m_module_initialized = true;

// If PM_PEER_RANKS_ENABLED is 0, these variables are unused.
UNUSED_VARIABLE(m_peer_rank_initialized);
UNUSED_VARIABLE(m_peer_rank_token);
UNUSED_VARIABLE(m_current_highest_peer_rank);
UNUSED_VARIABLE(m_highest_ranked_peer);

return NRF_SUCCESS;
}

ret_code_t pds_init()
{
ret_code_t ret;

// Check for re-initialization if debugging.
NRF_PM_DEBUG_CHECK(!m_module_initialized);

ret = fds_register(fds_evt_handler);
if (ret != NRF_SUCCESS)
{
NRF_LOG_ERROR("Could not initialize flash storage. fds_register() returned 0x%x.", ret);
return NRF_ERROR_INTERNAL;
}

ret = fds_init();
if (ret != NRF_SUCCESS)
{
NRF_LOG_ERROR("Could not initialize flash storage. fds_init() returned 0x%x.", ret);
return NRF_ERROR_STORAGE_FULL;
}

peer_id_init();
peer_ids_load();

m_module_initialized = true;

return NRF_SUCCESS;
}

pds_init()returns error code 0x0x00000086. When I force it to 0x0x00000000, the ERROR 3 disappears. But the debugger ends up then generating a "SOFT DEVICE ASSERTION FAILED" error via app_error_fault_handler():

void app_error_fault_handler(uint32_t id, uint32_t pc, uint32_t info)
{
__disable_irq();

switch (id)

case NRF_FAULT_ID_SD_ASSERT:
SEGGER_RTT_printf(0, "SOFTDEVICE: ASSERTION FAILED");
break;
case NRF_FAULT_ID_APP_MEMACC:
SEGGER_RTT_printf(0, "SOFTDEVICE: INVALID MEMORY ACCESS");
break;
#endif
case NRF_FAULT_ID_SDK_ASSERT:

assert_info_t * p_info = (assert_info_t *)info;
SEGGER_RTT_printf(0, "ASSERTION FAILED at %s:%u",
p_info->p_file_name,
p_info->line_num);
break;
}
case NRF_FAULT_ID_SDK_ERROR:

p_info->p_file_name,
p_info->line_num,
pc);
SEGGER_RTT_printf(0, "End of error report");
break;
}
default:
SEGGER_RTT_printf(0, "UNKNOWN FAULT at 0x%08X", pc);
break;
}
