关于OMAPL138加载Device Tree失败的问题

补充一下：

int size;
void *mem;

pr_debug(" -> unflatten_device_tree()\n");

early_print("%s:Start to unflatten_device_tree ... ...\n",__func__);

if (!blob) {
pr_debug("No device tree pointer\n");
return NULL;
}
early_print("%s:in here 1 ... ...\n",__func__);
pr_debug("Unflattening device tree:\n");
pr_debug("magic: %08x\n", fdt_magic(blob));
pr_debug("size: %08x\n", fdt_totalsize(blob));
pr_debug("version: %08x\n", fdt_version(blob));

early_print("%s:in here 2 ... ...\n",__func__);

if (fdt_check_header(blob)) { /*执行到这里就不返回了，即不报出错，也没有返回*/
pr_err("Invalid device tree blob header\n");
return NULL;
}
early_print("%s:in here 3 ... ...\n",__func__);

执行信息如下：
