Joyce, The ARM Cortex-A7 is feature-compatible with the Cortex-A15. We ran seL4 on the Cubietruck which is a dual-core Cortex-A7. Just enable CONFIG_ARM_CORTEX_A15 in your configuration.

I found seL4 official projects in below link. https://github.com/seL4 https://github.com/SEL4PROJ I use sel4test project that repo from https://github.com/seL4/sel4test-manifest.git And I found Xilinx zynq7000 support ARM Cortex-A9 in sel4test like below. File: sel4test/projects/sel4test/master-configs/zynq7000_release_xml_defconfig # # seL4 System # # CONFIG_ARCH_X86 is not set CONFIG_ARCH_ARM=y CONFIG_ARCH_AARCH32=y # CONFIG_ARM1136JF_S is not set # CONFIG_ARM_CORTEX_A8 is not set CONFIG_ARM_CORTEX_A9=y # CONFIG_ARM_CORTEX_A15 is not set # CONFIG_PLAT_EXYNOS54XX is not set I can’t find seL4 project support ARM cortex-A7. Does anyone find it? Thanks, Joyce Peng
