Hello experts ,
I found my I.MX8M board would automatically crashes under do not do anything,
( can't output log or key any command )
it might happen between 1~2 hour,
but after i keyin suspend order , the I.MX8M would not crash ,
this scenario can't happen in heavy loading and any also can't happen in any thread was running.
Device information as below:
CPU : MIMX8MQ6CVAHZAB
LPDDR4 : MT53B768M32D4NQ-062 WT:B
PMIC : PF4210
Hi Igor,

Dear Igor
It is not I.MX8M evk , but i used LPDDR4 512MB and 4GB to design in this case,
as so far , we tried to build 512MB and 4GB two versions base on the Linux 4.14.98.2.20,
the 4GB and 512MB both of two version crashed under do nothing , but 512MB version always crashed
between 1~2 hours , the 4GB version can stay idle 2~3 days.
this issue was so hardly to find out the root cause , because it was not to log out , and cant key in
any commands .
Do you have any thoughts and directions on this issue?
Hi Dylan
could you try to reproduce issue on i.MX8M EVK with latest
Demo Image Linux Binary Demo Files - i.MX 8MQuad EVK
If issue can not be reproduced, suggest to rerun ddr test and update image
with new lpddr4 calibration settings.
