Hi Yanyan, Thanks for your reply. I've already used only 1 core and a minimal device tree. Here's my apps/Arm/vm_minimal/rockpro64/devices.camkes:

GIC_REDIST_SGI_PADDR is introduced in a GICv3 virtualization support code change at https://github.com/seL4/seL4_projects_libs/commit/143d48c0f99d3e35a9fd27deb7.... Do you know what does the error "sel4utils_reserve_range_at_no_alloc@vspace.c:595 Range not available at 0xfef10000, size 0x10000" mean? Thanks.
