HI all,
long time no see
sorry to bother you again
I am using maaxboard yocto mickledore version https://github.com/Avnet/meta-maaxboard/tree/mickledore ,
and after enable optee, the kernel changes memory size from 2G to 3G wrongly , so if I run : du -sh, find .. such as recursive commands, it will be out of memory, the kernel will be crashed .
I enable optee in meta-maaxboard/conf/machine/maaxboard.conf
MACHINE_FEATURES += " optee wifi bluetooth bcm43455"
anybody know why make this issue. I did in sumo version, no this issuebefore
My Qz:
1.how to fix it in kernel for adding patches
2. if can not fix in kernel ;or how to forcefully set memory to 2G in /boot/uEnv.txt
I tried all versions from zeus to mickledore have the same issue, but I ported by myself a few years ago, sumo version NOT had this issue.
thank you so much.
I also posted my QZ here:
see my debug info:
