My test app is as follows, it works fine.
```c
rtems_task Init(
    rtems_task_argument ignored)
{
  puts("hello");

  const void *fdt;
  int node;
  int len;
  const uint32_t *val;

  fdt = bsp_fdt_get();
  node = fdt_node_offset_by_compatible(fdt, -1, "brcm,bcm2835-sdhci");

  printf("%d\n", node);

  val = fdt_getprop(fdt, node, "reg", &len);

  printf("%lX %lX\n", fdt32_to_cpu(val[0]), len);


  puts("end");

  rtems_shutdown_executive(0);
}
```

output:
```
hello
20748
7E300000 8
end
```
