addtask install after do_build

I am using SWUpdate. I can build their kernel and run it on my device. However I cannot login as root or any user I have created. It seems this could be related to user permissions in the getty serial terminal ttymxc0. So I am attempting to add a script to init.d. The script contains

#!/bin/sh

# Set permissions on ttymxc0
chmod 660 /dev/ttymxc0
chown root:tty /dev/ttymxc0

The bitbake file I am appending to is swupdate-image.bb. This file does not do much. It does not have a do_install section. So I am attempting to add one. However it is never run. Can anyone speculate as to why?

Answer 1

You actually noticed that the file swupdate-image.bb require an other file swupdate-image.inc.

You should pay attention to this line:

${@bb.utils.contains('SWUPDATE_INIT', 'tiny', 'virtual/initscripts-swupdate', 'initscripts systemd', d)} \

${@bb.utils.contains() is a (Python) function. Basically it will check the SWUPDATE_INIT variable, if there is a match with tiny then it will return virtual/initscripts-swupdate to IMAGE_INSTALL. Else, it will return initscripts systemd to IMAGE_INSTALL.

So you should only set your variable SWUPDATE_INIT= "tiny" in a .bbappend file.

Adding this should install rcS.swupdate in your final image according to initscripts-swupdate recipe:

https://github.com/sbabic/meta-swupdate/blob/master/recipes-core/initscripts-swupdate/initscripts-swupdate-usb.bb

N.B: I have noticed that you added resize2fs. If you want to add this binary make sure that the right kernel flag is set ! You will more likely need to create a .bbappend file and add the following :

EXTRA_OECONF_append_class-target = " --enable-resizer"
