compiler: keil

To solve the hardfault issue (SOFTDEVICE: INVALID MEMORY ACCESS, INFO : 0x2) , I start with changing compiler optimization level to 0.

optimization level 3 is compiled well, but level 0 doesn't.

Error: undefined symbol __aeabi_assert (referred from nrf_802154.o)

To solve my original issue (SOFTDEVICE: INVALID MEMORY ACCESS, INFO : 0x2) , I would wait your advice.

======================== ADD =========================

I found __aeabi_assert function in nrf_802154_debug.c #if ENABLE_DEBUG_ASSERT condition. So I set ENABLE_DEBUG_ASSERT=1 and optimization level 0, and Successfully compiled.

But, My code is always stuck somewhere.

I don't understand this pictures. What this means about?

It is hard to tell what is wrong with the information you provided. 

__aeabi_assert is defined in SDK\components\libraries\assert\assert.cassert.c. I am not sure why changing optimization level affects its inclusion.

My SDK version 15.2.0 doesn't have SDK\components\libraries\assert\assert.cassert.c.

I update my question. please check it.

you are using 802.15.4 modules here, so i thought you should be using \nRF5_SDK_for_Thread_and_Zigbee_2.0.0_29775ac. You find the definition here.

nRF5_SDK_for_Thread_and_Zigbee_2.0.0_29775ac\components\libraries\assert\assert.c

If you are for some reason using this with SDK15.2, then i suggest you copy this into SDK15.2 folder and add this into your project to be compiled.
