[beagleboard] Workaround to speed boot times for BBB debian image

[Gunjan Gupta]

Hi,

I noticed that BBB takes around 1 and half minute to finish the boot 
process because of /etc/init.d/networking service taking too much time to 
execute. I did some modifications into the networking script and the boot 
time reported by systemd got reduced to about 5 secs while the network 
becomes available in less than 15 seconds.

I have made the changes in the start procedure as follows

start)
if init_is_upstart; then
exit 1
fi
process_options
check_ifstate

if [ "$CONFIGURE_INTERFACES" = no ]
then
log_action_msg "Not configuring network interfaces, see 
/etc/default/networking"
exit 0
fi
set -f
exclusions=$(process_exclusions)
log_action_begin_msg "Configuring network interfaces"
if [ -x /sbin/udevadm ]; then
if [ -n "$(ifquery --list --exclude=lo)" ] || [ -n "$(ifquery 
--list --allow=hotplug)" ]; then
udevadm settle || true
fi
fi
# Lets run this if block in background to speed the boot process
( if ifup -a $exclusions $verbose && ifup_hotplug $exclusions 
$verbose
then
log_action_end_msg $?
else
log_action_end_msg $?
fi ) &
;;


I know its a ugly hack but speeds up the process. I know installing some 
other softwares like connman, etc also speeds up the process but I didn't 
wanted to install them. Any other suggestions are welcome.

[beagleboard] Re: debian testing: 2014-09-03 (goodbye vfat release)

[Gunjan Gupta]

I am sorry as what I am posting is not entirely related to this thread but 
is a feature request for debian.

I liked the console image as it saves a lot of disc image by removing all 
the GUI softwares. I am running my BBB headless mostly controlling it using 
ssh and by bone portal. For console image, I guess addition of the bone 101 
portal will be good as it is used over the network and is not related to 
lxde.

Could you please add the node.js, bone 101 and cloud9 back to the console 
image?

Hi Robert,

I have built a customized debian image based on your latest imagebuilder 
script, and I am also facing this issue. Is it still broken? If yes, could 
you please tell the steps to get it working?

[beagleboard] Question regarding squashfs

[Gunjan Gupta]

Hi Robert,

I am using a BBB Rev A5C which only has 2 GB of emmc storage. In order to 
conserve the storage, I am thinking to use squashfs for my root 
file-system. The layout I am planning will be some thing like a /boot 
partition, / partition, and then another partition that will act as an 
overlay over squashfs. Also I am planning to have a option available so 
that I can enable a separate overlay for the /home in case a SD card is 
present.

I don't exactly know the amount of changes required for this, but roughly I 
guess I have to customize the kernel and the initrd at the very least. 
Could you please comment on whether this kind of system is possible and if 
it will have any impact on performance of the system.

With Best Regards
viraniac

Re: [beagleboard] Question regarding squashfs

[Gunjan Gupta]

Hi William,

I am currently using a custom image built with Robert's Image Builder 
script. It's a console image with all the things install that I need and 
the image size is about 800MB. Based on my experience with squashfs on x86 
platform, I know if squashfs is used this can be brought down to 200 to 300 
MB. Thats why I am willing to use squashfs.

I have searched on the forum and have found some posts regarding squashfs, 
but it doesn't look like any one ever succeeded to built an image or 
atleast no one shared there success on the forum.

Could you comment about whether using squashfs willl be practical or not 
for BBB

Thanks & Regards

[beagleboard] Re: where can i buy beagle board black in india?

[Gunjan Gupta]

Hi Santosh,

If you are not belonging to a company and ordering it for your personal 
use, you can also order it from crazypi.com. I ordered mine from there as I 
was not seeing any progress when ordering from element14. Crazypi delivered 
it for me in 2 days.

Hi,

You have used both the 5V power source and the mini usb cable. I guess 
thats why your board got fried up. Use only one of them for the next time.

Hi Robert,

Thanks for reminding me of systemd-analyze. Completely forgot about that.

Here is the output of the command

=

  2402ms ssh.service

  1181ms wpa_supplicant.service
  1120ms systemd-logind.service
  1086ms connman-vpn.service
  1027ms boot_scripts.service

66ms remount-rootfs.service
48ms console-setup.service
38ms sys-fs-fuse-connections.mount

==

So it looks like networking.service is eating up all the time. Is it safe 
to disable this service with connman installed?

I guess that comes bundled with debian by default. I have build some custom

Re: [beagleboard] Re: Help Needed : Custom built debian image

[Gunjan Gupta]

I haven't changed the content of that, So that will be having some default 
values. I have deleted the old images and am building it again with the 
newly customized script with all locale support and with connman and having 
networking.service as disabled. Will there be any consequences for having 
networking service disabled?

Re: [beagleboard] Re: Help Needed : Custom built debian image

[Gunjan Gupta]

Hi Robert,

One thing that I forgot to mention was that I am interacting with BBB over 
ssh. I guess its taking LANG from my host machine. If I check LANG from 
lxterminal, it comes as en_US and everything works fine.

Can we force it to use en_US on ssh also?

[beagleboard] Custom built debian flasher Image not working

[Gunjan Gupta]

Hi

I have a custom built debian flasher image which is not flashing the emmc. 
The image has the lxde related and node packages removed. I have added 
halevt, xinit, chkconfig and oracle jre to the image. The non flasher 
version of the image is working fine but not the flasher version.

Please help,

Regards
viraniac

[beagleboard] Re: Help Needed : For setting up plymouth on Beaglebone Black

[Gunjan Gupta]

Hi,

No reply in days, but I found the solution. Posting it for any one needing 
this information in the future.

Here are the steps needed to be followed for setting up plymouth on 
beaglebone black running debian or ubuntu:

Step 1) Install Plymouth-DRM.

# apt-get install plymouth-drm

Step 2) Select a theme for boot splash.

# plymouth-set-default-theme --list   # this lists 
the available themes for plymouth

# plymouth-set-default-theme joy

Step 3) Update initramfs

# update-initramfs -u

Step 4) Copy the newly created initrd.img file to /boot/uboot folder

# cp /boot/initrd.img-$(uname -r) /boot/uboot/

Step 5) Update the initrd file name in the /boot/uboot/uEnv.txt

#initrd_file=initrd.img
initrd_file=initrd.img-3.8.13-bone47

Step 6) enable splash support by adding the following to 
/boot/uboot/uEnv.txt. 

# Place this at the bottom of the last line starting with optargs

optargs=splash plymouth.ignore-serial-consoles ${optargs}

just restart your beaglebone, and it will work.

Hope this will be helpful for someone.

Regards
viraniac

[beagleboard] Re: Custom built debian flasher Image not working

[Gunjan Gupta]

Hi,

I am really hoping Robert or someone else will be able to help me on this. 
My guess for this is that halevt is keeping the partitions of emmc mounted 
which might be causing the script to fail. Another reason can be that I 
have disabled the root account. But as my custom GUI is running as root, I 
don't think the flasher script should have a problem running as root.

If you guys need, I can upload the scripts that I modified for my own 
customizations.

Regards
viraniac

Hi,

Alright, got it was due to my keyboard being plugged in. Its strange though 
that this can be a issue while flashing.

Thanks for help.

Re: [beagleboard] Re: Help Needed : Custom built debian image

[Gunjan Gupta]

Hi Robert,

Though I am commenting the rfs locale strip=enable line. but its still 
generating only en_US.UTF8 locale. How to force it to generate all locales 
(other than executing dpkg-reconfigure)?

Re: [beagleboard] Re: Custom built debian flasher Image not working

[Gunjan Gupta]

Hi Robert,

Actually as it turned out, it was not a problem of power or keyboard. My 
initial analysis was wrong. It worked one time that got me thinking about 
this being keyboard fault, but it wasn't. I searched for the term emmc and 
flash in the filenames on my sd card and finally found the log file. The 
log file had a error rsync error 

chgrp failed: operation not permitted

I checked the /tmp/boot and found that the owner of the files was root and 
group owner was plugdev. So I modified the emmc flasher script to stop the 
halevt service, and now its working fine.

Thanks for replying. Please also reply to the locales issue in the other 
thread.

Regards
viraniac

Hi Robert,

Thanks for replying. I will add that package to my package list. 120 MB 
won't be a problem as my disk space being used is currently near to 800MB 
only.

Re: [beagleboard] Re: Help Needed : Custom built debian image

[Gunjan Gupta]

Robert,

My system while booting shows a debian boot splash. Then it shows a black 
screen for about 4 to 5 seconds before displaying the java program that I 
am running as my GUI. 

I am using startx command configured in /etc/rc.local to start the X 
environment and a /root/.xinitrc file to start my java program. Is there 
something I can do to reduce this 5 second of blank display time?

Regards
viraniac
