I hope to have some way to decide whether to boot the system from the emmc or from the USB drive when the Jetson TX2 NX starts up. Is this achievable? I switched the boot device now by modifying/boot/extLinux/extlinux.cn, but this requires modifying the file and restarting after booting. Is there any other way?
你所謂的"boot the system"並不完整正確…
extlinux.conf只能改rootfs mount的位置 真的開機用的boot device要從uboot看.
比方說好了, 你現在的kernel跟extlinux.conf檔案都還是從emmc讀的. 跟你的usb drive沒有關聯. 這並不是完整的boot the system from usb drive
请问如何进入到uboot看我的boot device设置？
我在U-Boot中修改启动顺序，将uboot中的启动顺序修改为usb0为第一启动项后usb0的系统启动失败了，Jetson启动了emmc中的系统。我的usb设备中的系统是直接使用dd命令直接复制emmc中的系统得到的。是否因为是这个原因？如果是，能否给我具体的usb设备系统烧录方法。
Hi,
抱歉 忘了說明 其實TX2系列沒有辦法從USB開機 這是一個known issue.
請改用nvme之類的進行開機.
好的。我注意到你发送的链接中 Flashing to a USB Drive 这部分下文提到了 Flashing to an SD Card ，请问烧写系统至SD卡中现在是否支持TX2 NX？
如果你要的是燒錄到sdcard, 那你得用的是initrdflash, 不能用flash.sh.
同一份document → Flashing with initrd
我在烧录中遇到了问题。我执行过的命令：
sudo apt install libxml2-utils simg2img network-manager abootimg sshpass device-tree-compiler
#cd Linux_for_Tegra
tar xvjf secureboot R32.7.2 aarch64.tbz2
systemctl stop udisks2.service
接下来我将TX2 NX进入恢复模式，保持SD卡安装在设备上，将TX2 NX与Host PC连接，开始烧写。
sudo ./tools/kernel_flash/l4t_initrd_flash.sh jetson-xavier-nx-devkit-tx2-nx mmcblk1p1
终端输出停止在：

這partition錯了吧
抱歉这里拼写错误，将其替换为mmcblk1p1似乎得到了同样的错误：
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-only jetson-xavier-nx-devkit-tx2-nx mmcblk1p1
#输出

Please use such command. Replace the “your_board_config” in above to match the one you are using for flash.
