I've made the necessary changes to UART variables, and lowered the amount of RAM by making RAM0_SIZE = 0x20000000. After executing the image.elf on Sabre Lite, I got the following output: ## Starting application at 0x10001000 ... :virt_alloc: Allocator 0x200f40b4 dump: Block: [0x1000,0x10001000] size=0x10000000 avail=0x10000000 max_avail=0x10000000 Block: [0x105ad000,0x20001000] size=0xfa54000 avail=0xfa54000 max_avail=0xbfe5b000 Block: [0x201a4000,0x201a5000] size=0x1000 avail=0x0 max_avail=0x0 Block: [0x201a5000,0xe0000000] size=0xbfe5b000 avail=0xbfe5b000 max_avail=0xbfe5b000 Block: [0xf0004000,0xf0005000] size=0x1000 avail=0x0 max_avail=0xbfe5b000 Block: [0xf0007000,0xf0008000] size=0x1000 avail=0x0 max_avail=0x0 Block: [0xf0009000,0xf000a000] size=0x1000 avail=0x0 max_avail=0xffe5000 Block: [0xf000a000,0xfffef000] size=0xffe5000 avail=0xffe5000 max_avail=0xffe5000 => mem_size=4018765824 (3832 MB) / mem_avail=4018749440 (3832 MB) :phys_alloc: Allocator 0x200f3048 dump: Block: [0x1061f000,0x10620000] size=0x1000 avail=0x0 max_avail=0x0 Block: [0x10620000,0x10621000] size=0x1000 avail=0x0 max_avail=0x1f9dd000 Block: [0x10621000,0x10622000] size=0x1000 avail=0x0 max_avail=0x0 Block: [0x10622000,0x10623000] size=0x1000 avail=0x0 max_avail=0x1f9dd000 Block: [0x10623000,0x30000000] size=0x1f9dd000 avail=0x1f9dd000 max_avail=0x1f9dd000 => mem_size=530452480 (505 MB) / mem_avail=530436096 (505 MB) :io_mem_alloc: Allocator 0x200f512c dump: Block: [0x0,0x1061f000] size=0x1061f000 avail=0x1061f000 max_avail=0xcfffffff Block: [0x30000000,0xffffffff] size=0xcfffffff avail=0xcfffffff max_avail=0xcfffffff => mem_size=3764514815 (3590 MB) / mem_avail=3764514815 (3590 MB) :io_port_alloc: Allocator 0x200f6198 dump: => mem_size=0 (0 MB) / mem_avail=0 (0 MB) :irq_alloc: Allocator 0x200f7204 dump: Block: [0x0,0x1] size=0x1 avail=0x1 max_avail=0x1 Block: [0x2,0x1d] size=0x1b avail=0x1b max_avail=0x3e2 Block: [0x1e,0x400] size=0x3e2 avail=0x3e2 max_avail=0x3e2 => mem_size=1022 (0 MB) / mem_avail=1022 (0 MB) :rom_fs: ROM modules: ROM: [101a6000,101a6158) config ROM: [10182000,101a2178) init ROM: [10105000,101819a4) ld.lib.so ROM: [101a3000,101a5598) test-log kernel initialized Genode 17.02 504 MiB RAM assigned to init [init -> test-log] hex range: [0e00,1680) [init -> test-log] empty hex range: [0abc0000,0abc0000) (empty!)

Is this the desired output from "log"?
