debian - 如何使用 Debian 8.2 镜像刷新 BeagleBone Black eMMC？

Question

This site , 说...

To turn these images into eMMC flasher images, edit the /boot/uEnv.txt file on the Linux partition on the microSD card and remove the '#' on the line with 'cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh'. Enabling this will cause booting the microSD card to flash the eMMC.

uEnv.txt 文件中不存在这样的行。 我也没有看到 init-eMMC-flasher-v3.sh文件在启动分区上的任何位置，尽管它可能在隐藏分区上(至少对 Windows 是隐藏的)。

我试过保持 S2(这似乎是一种较旧的(也许？)闪烁方法)但没有成功。

说明中提到的那一行是uEnv.txt的最后一行.我刚刚下载了 bone-debian-8.2-tester-2gb-armhf-2015-11-12-2gb.img.xz 的新副本和 /boot/uEnv.txt在我取消注释 eMMC flasher 命令后看起来像这样:

##enable Generic eMMC Flasher:

最后一行是您要查找的行。如果由于某种原因它不存在，只需添加它并保存文件。然后当从 SD 启动时，LED 将显示“来回”模式，表明 eMMC 正在闪烁。
