So, we actually are putting the probe at address 0x10000530, and uaddr()
does return that address from within the probe context. Good. But our
translation table doesn't contain "print_hw" at that address.
Could you check some things?
- Can you run it under gdb and put a breakpoint at print_hw,
which address does that give?
- What is the output of eu-readelf -s helloworld?
Thanks,
Mark
