Crash issue on sdk v2.9.0

[Leo Mo]

SOC: nrf52840

SDK: v2.9.0

Device is a central, it connected to 16 peripherals, these peripherals will power on 90 seconds and then power off 10 seconds(one cycle).

After ten days of operation, there will be a crash.

Has anyone run into this problem? How do you solve it? Thank you!

Crash 1, reason is K_ERR_KERNEL_OOPS=3.

Crash 2, reason is K_ERR_ARM_BUS_IMPRECISE_DATA_BUS=26.

CONFIG_LOG_PROCESS_THREAD_STACK_SIZE=768

Hi Leo,

Unfortunately, I haven't encountered them before, but I have started an internal inquiry about them.

ASSERT: 33,748 is still under investigation. We are not certain about this yet.

As for ASSERT: 53, 295, could you please let me know if you are using LFRC or LFXO? Do you encounter this on one particular unit, or multiple units?

[Leo Mo]

Hi Hieu,

I use the LFRC(CLOCK_CONTROL_NRF_K32SRC_RC=y).

Only two units encounter this issue(ASSERT: 53, 295) so far.

[Hieu]

Hi Leo,

Sorry I should have asked earlier, but how many units total are you testing? 

Of the two units that have that problem, does it consistently occur again?

[Leo Mo]

Hi Hieu,

There are 4 units under testing, two of which are connected to J-Link in debug mode.

Only the devices connected to J-Link have encountered this issue (ASSERT: 53, 295).

I want to know what these error codes mean. If they are caused by the application, I can make changes on my side.

 Hi, Hieu

 Hieu 

I would like to know the meaning of these error codes(ASSERT: 53, 295, ASSERT: 33,748) ; can you ask the software engineer directly?
