Ls1020a porting openil, optee function verification failed

1784857911 — Thu, 04 Apr 2019 01:27:03 GMT

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?

See the Section 5.2.4.3 of LSDK 19.03 documentation about compile OP-TEE binary:

Have a great day,
