I need optee_os support for Maaxboard in yocto project, any help?

gonewtinwind

I have successful built yocto project image with the maaxboard company's kernel and u-boot code at here: https://www.element14.com/community/message/288659/l/re-how-can-i-build-an-image-for-the-maaxboard-myself#288659

 

 

it seems imx original  imx8mqevk board yocto project support optee_os.

why my yocto image and maaxboard company's yocto image with shipment do NOT support optee_os?

do you know what different between original  imx8mqevk  u-boot code and maaxboard company's uboot code ? or something else differences?

I am trying to find the differences.

can you give me some ideas about it  I checked the linux kernel  optee config, it's chosen by kernel config. the issue is not in kernel.

 

ps.

I posted my yocto project tar file  at here for your reference:
