Hello,
my goal is to load OP-TEE after BL31 and before u-boot, so I enabled CONFIG_SPL_OPTEE_IMAGE.
But it fails to build (tested current master):
$ make -j$(nproc) CROSS_COMPILE=aarch64-linux-gnu- rock-pi-4-rk3399_defconfig all
./arch/arm/include/asm/unified.h: Assembler messages: ./arch/arm/include/asm/unified.h:12: Error: unknown pseudo-op: `.syntax' common/spl/spl_optee.S:11: Error: operand 1 must be an integer register -- `mov pc,r3' make[3]: *** [scripts/Makefile.build:292: spl/common/spl/spl_optee.o] Error 1 make[2]: *** [scripts/Makefile.spl:533: spl/common/spl] Error 2 make[2]: *** Waiting for unfinished jobs....
Without CONFIG_SPL_OPTEE_IMAGE the board starts like this: TPL -> SPL -> BL31 -> u-boot
What's the correct way to start OP-TEE on rk3399?
Any ideas?
Thanks -- Christoph
