A question about Beaglebone black boot image

Embedded Linux Discussions
1

Hi
I installed debian on sd card by referring to the following site.
[https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone+Black]

When I insert the sd card into the BBB and power it on, linux runs fine.

But when I install debian on emmc using a shell script,
the message ‘file has vanished’ keeps appearing and execution ends.
then when I boot from emmc, linux stops booting with error message and doesnot work any more.
I don’t know why.
could you let me know how to do fix it?

Error message - ‘file has vanished’

@taek8461, You broke “bbb-eMMC-flasher-eewiki-ext4.sh” by calling it with /bin/sh…

sudo /bin/sh /opt/scripts/tools/eMMC/bbb-eMMC-flasher-eewiki-ext4.sh

bbb-eMMC-flasher-eewiki-ext4.sh contains a bash-ism in all the rsync calls…

rsync -aAx /* /tmp/rootfs/ --exclude={/dev/*,/proc/*....}

So by running it with /bin/sh, the --exclude parameter breaks and rsync tries to copy things it can’t… /proc/* etc…

So change your script to call it with /bin/bash

sudo /bin/bash /opt/scripts/tools/eMMC/bbb-eMMC-flasher-eewiki-ext4.sh

and it’ll work.

Regards,
