@haaland 指令是没错的，使用exit退出adb shell，后在执行adb push xxx xxx

可以试一下把你的Makefile文件和Kconfig文件一起上传上来，官方的例程没有问题的，很大概率是你tab和空格的问题

@whycan 了解了，感谢晕哥

@whycan 所以可以理解成是为了一个限制或者说是明确目前所使用的是内核版本是多少？

@yuzukitsuru 其实我想知道为什么需要这个超链接呢？而且linux文件夹也链接了linux5.4

@bjxx159 感觉得重新指定hello world的交叉编译工具链试试，前面没有看到编译的实际过程，不好下判断

@xiaowenge 了解了，所以其BROM默认启动地址应该没有没有变化吧？

新版的D1 User Manual似乎没有对BROM初始启动地址的描述了，还是说我漏看了呢？

在SDK中修改了对应的内容后，也还是会报该错误，
错误log如下：

修改之后的SDK文件如下：

void sunxi_set_cur_vol_work(struct work_struct *work)
{
#if !defined(SUNXI_USB_FPGA) && defined(CONFIG_POWER_SUPPLY)
	struct power_supply *psy = NULL;
	union power_supply_propval temp;

	if (of_find_property(g_udc_pdev->dev.of_node, "det_vbus_supply", NULL))
		psy = devm_power_supply_get_by_phandle(&g_udc_pdev->dev,
											   "det_vbus_supply");
	if (!psy || IS_ERR(psy)) {
		DMSG_PANIC("%s()%d WARN: get power supply failed\n",
				   __func__, __LINE__);
	} else {
		temp.intval = 2500;

		power_supply_set_property(psy,
								  POWER_SUPPLY_PROP_INPUT_CURRENT_LIMIT, &temp);
	}
#endif
}

@whycan 好像取消了编译也还是不行，请问还有别的可能吗
