'Stress' tool on imx6quad always crashes

[shilpasb]

Hi ,

I am running 'Stree ' tool on a customised imx6q processor board.

My DDR3 configuration is 1Ghz, with freq set to 400 Mhz

I run the tool with the options given below

stress --cpu 8 --io 4 --vm 4 --vm-bytes 200M --timeout 1d &

Kernel always crashes after sometime(30 mins or less).

The log when the kernel crashes is given below

Unable to handle kernel NULL pointer dereference at virtual address 0000000b

Can anyone please help in solving this issue? It is quite urgent.

Hi shilpa

had you run ddr test and rebuilt uboot with new ddr calibraion coefficients

i.MX6/7 DDR Stress Test Tool V2.52 | NXP Community

Hi Igor,

Thanks for the input....

As you suggested, we have set the DDR frequency to 528 Mhz and we did the calibration .

With the calibrated values we are able to run the stress test for more than 24 hours .

We had set up 5 systems to run the same stress test, out of which 3 boards have continuously run for 5 days without any crash. 2 boards failed after a day . I have attached the logs for your reference.

my doubt is , 

1. Is there any constrains on running the below test.

stress --cpu 8 --io 4 --vm 4 --vm-bytes 200M --timeout 5d &

2. What is the maximum stress that can be loaded on IMX6Q processor with DDR3 clk frequency of 528 Mhz and density of 1GB?

3. What else to be taken care apart from DDR3 configuration for the below failures ? 

The log of the failed board is given below
