If you want to test with QEMU v8, just simply: $ repo init -u https://github.com/OP-TEE/manifest.git -m qemu_v8.xml $ repo sync $ cd build Apply my patch https://github.com/OP-TEE/build/pull/821 In kconfigs/u-boot_tl.conf, remove 'CONFIG_BLOBLIST_SIZE=0' and add 'OF_BLOBLIST=y' $ make toolchains $ make run Regards, Raymond > Regards, > Simon
