Hi, I am attempting to run the `loopback.exe` sample application provided with RTEMS on the PowerPC qoriq_e6500_64 BSP, but unfortunately it is crashing.
The crash seems to be coming from here: `cpukit/libnetworking/rtems/rtems_glue.c` line 230. It appears to be due to the fact that the `routedomain` object is being placed in the `.data.rel.ro` section which is read-only, so writing to it causes the crash. ``` $ powerpc-rtems5-objdump -x loopback.exe | grep routedomain 000000000404dd70 g O .data.rel.ro 0000000000000050 routedomain ``` Has anyone seen this issue before, or know how to fix it? Maybe I'm missing a compiler argument or something? I've included the console output below. Thanks!
