Here is the build process I follow for above. export ARCH=arm64 export CROSS_COMPILE=aarch64-linux-gnu- make mrproper git pull origin cp -v ../arm-trusted-firmware/build/rk3399/release/bl31/bl31.elf ./bl31.elf make odroid-n1_defconfig all u-boot.itb tools/mkimage -n rk3399 -T rksd -d ../rkbin/bin/rk33/rk3399_ddr_800MHz_v1.23.bin idbloader.img cat spl/u-boot-spl-dtb.bin >> idbloader.img cd ../rkbin tools/trust_merger RKTRUST/RK3399TRUST.ini cd - cp -v ../rkbin/trust.img . Now it fails to boot the kernel. Earlier In my testing using memtester # memtester 512M 1 test case pass. # memtester 1024M 1 testcase failed with locked So I could only conclude that less than 1GB is available for the kernel and rest of the memory is not mapped. Please can you share some memory testcase that I could used on any board to verify that memory is allocated correctly by the boot loader to the kernel.
