kernel panic when booting

[asmaa]

Hi all,

I am getting this error when booting from my custom board based on imx6q. I have ported android image on my board. what could possibly be wrong. can someone please point me?

Hi Asma

usually kernel panic happens due to memory errors so one can run

ddr test https://community.nxp.com/docs/DOC-105652 

and update uboot with new ddr calibration seetings found from ddr test in

mx6q_4x_mt41j128.cfg\mx6sabresd\freescale\board - uboot-imx - i.MX U-Boot 

Best regards
igor

Hi igorpadykov‌,

it is not the memory because I have ran non android kernel on it. After digging  a bit more, I got to know memory is getting exhausted/overcommitting the memory and it is giving uuc is invoking killer.

uuc invoked oom-killer: gfp_mask=0x24200ca(GFP_HIGHUSER_MOVABLE), nodemask=0, order=0, oom_score_adj=0
CPU: 0 PID: 102 Comm: uuc Not tainted 4.9.11+ #1
Hardware name: Freescale i.MX6Q(Device Tree) 

 what is uuc?

How can I allocate RAM memory to be optimzed, where do I can change this in source code?

[igorpadykov]

for uuc one can look on

GitHub - NXPmicro/imx-uuc: A Daemon wait for Freescale/NXP mfgtools host's command 

UUC source code and initramfs 

For allocation RAM memory recommended to look in software documentation which

is used for that case.

Best regards
igor

[asmaa]

Sorry I didnt get you. Which software documentation for iMX6Q (please specify name) and where can we change this in kernel source code?

[igorpadykov]

one can try to debug it using mfg tool sources, one can look on

GitHub - NXPmicro/mfgtools: Freescale/NXP I.MX Chip image deploy tools. 

[asmaa]

igorpadykov‌ I am asking about the document which tells about memory allocation for iMX6Q.

[igorpadykov]

sorry I am not aware of such document. May be helpful

https://www.element14.com/community/community/designcenter/single-board-computers/riotboard/blog/201... 

[asmaa]

I am not asking anything about mfgtool. I am asking about memory allocation of RAM and different memories like L1/L2 instruction and data cache. where are they set in source code. Either uboot or kernel source code?

If you dont know, its ok. I will create another thread someone else might be able to help me.

Hi asmaa,

I think so you have solved the issue , now myself met with the same issue can you please let me know why it is giving kernel panic and where to do changes.

Regards.
