after enabling optee in maaxboard, memory size change from 2G to 3G wrongly,from yocto zeus to mickledore

[gitgonewithwind]

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:

any help?
I changed and checked dtb , ,imx-boot, optee, u-boot , almost I changed every thing that suggestions from the internet and chatgpt. but I can not make the memory size correct 2G. It always set to 3G.
where is the issue?

[gitgonewithwind]

I posted the issue in optee too:
OP-TEE/optee_os#7388

[gitgonewithwind]

here is my porting tips  5 years ago in sumo yocto, at that time, the maaxboard was embedded test company in SHENGZHEN,China not in avnet and no yocto source code.

I ported, and added  kernel , uboot, mkimage  from embeddedtest and imx8mq_evk to yocto sumo. it worked well. but now all version in avnet yocto never work well. it is funny the maaxboard-mini works well

after avnet taking it, the  maaxboard optee never worked well for maaxboard!

https://github.com/gitgonewithwind/imx-yocto-bsp-maaxboard?tab=readme-ov-file

[gitgonewithwind]

any help, why maaxboard-mini works well? I changed imx-atf, imx-boot,optee-os and u-boot to almost same as maaxboard-mini, but maaxboard can not boot up. it seems imx-atf source code NOT ported before. can not only changing size defines to fix it

[gitgonewithwind]

I fixed the issue, later I will post the patches.

[gitgonewithwind]

see patches: please add it in avnet source code from sumo to update version
