To be more precise, .text begins itself from 'reset_vector' address (it
is public label). See arch's target.ld and vectors.S sources.

It is strange value as 0x64008111 is odd address, but 'reset_vector'
address for your arch should be aligned on 2-bytes boundary. I believe
that entry address is 0x64008110 or some even address. Try in GDB
(gdb) print $pc
(gdb) print reset_vector
% arm-eabi-objdump -d app.elf | more
I think you see 0x64008110.

Just wondering, 'go 0x640008110' does not work?
