Hi, I am currently porting openil on the ls1020a board and failing to verify the optee function.
I build the openil project with
make nxp_ls1021atsn_optee-sb_defconfig&&make 2>&1 | tee build.log
and get sdcard.img, rootfs.ext2.gz.uboot, ls1021a-tsn.dtb, uImage, tee.bin and other files.
I burned rootfs.ext2.gz.uboot, ls1021a-tsn.dtb, uImage to the board on the uboot command line, and boot the system with
bootm 83000000 88000000 8f000000
However, after startup, the tee device node dev/teepriv0 is not generated,
Dmesg | grep tee
Optee: probing for conduit method from DT.
Optee: api uid mismatch
Why？Is it because I had not burned the optee firmware？
Because my board does not have an sdcard interface, I can not burn the sdcard.img. Is there any other way to burn the optee firmware? Is there any detailed guidance document in this regard?
