Hello NXPs,
Release: Yocto-Sumo (4.14.98_2.0.0_GA)
Board: i.MX8MQ EVK based custom board
We're working on iMX8MQ based custom-designed board with 2GB DDR4 RAM (MCIMX8M-EVK 3GB LPDDR4 RAM) now we're having an issue when doing stress test RAM in linux.
The system always hang when doing RAM stress test with more than 760MB RAM.

I've already done RAM testing with DDR Tool and mtest in Uboot and all PASSED, then configured the linux system recognized with 2GB RAM.
Does anyone provide the solution for this issue? Any guidance or suggestions will be really helpful.
Best regards,
