ReImaging an n810 - A Two Step Process

If you would like to know more about how the process was developed you can read more here

Step 1: Prepare device

• Remove all batteries and leave them out
• Remove all SD cards, separate cards+adapters into two bowls
• Log in as maemo/maemo
• Start a terminal window
• run:

su - #password will be on front of machine
cd /flashing-hg/production-sd/

for n810 in dead_pile:

./moz-prep.sh
...
Suitable USB device not found, waiting

• plug in USB in n810 (USB logo is facing up)
• replace battery and casing
• plug in Charger
• verify that small USB logo is displayed in top right corner of n810
• on terminal display, wait for "The device root device is now 'mmc'"
• unplug USB and power
• watch device display debug info and then power itself off

Step 2: Clone SD card

• verify no MicroSD cards are in USB hub's card readers
• plug USB cable and power cable into USB hub
• insert MicroSD Cards into card readers
• Verify that you are in '/flashing-hg/production-sd/' as root
  • if not run:

$ su - #password will be on front of machine
# cd /flashing-hg/production-sd/
# ./bulk-image.sh 
Please specify devices from this list
/dev/sde1
/dev/sdh1
/dev/sdd1
/dev/sdf1
/dev/sdg1
/dev/sdc1
BULK IMAGING COMPLETED
# ./bulk-image.sh e h d f g c 
NEVER CHOOSE a or /dev/sda
wait approx 6-14minutes
...
All done on /dev/sde
All done on /dev/sdh
All done on /dev/sdd
All done on /dev/sdg
All done on /dev/sdc
All done on /dev/sdf
BULK IMAGING COMPLETED

• remove sd cards
• unplug usb hub power and usb cable (they get hot)
• put card into holder, and holder into n810
• switch on n810, wait for it to obtain wireless IP address
• on imaging machine terminal, do

[root@maemo-flashing production-sd]# ssh root@maemo-n810-15

maemo-n810-ref:~# cat /etc/hostname
maemo-n810-15
# verify there is no file called /builds/standalone.txt
maemo-n810-ref:~# rm /builds/standalone.txt
rm: cannot remove '/builds/standalone.txt': No such file or directory
reboot, and important to use "exit" to avoid hanging terminal on imaging machine
maemo-n810-ref:~# reboot; exit

If something goes wrong

• unplug usb hub from usb cable and power
• reboot computer
• start from scratch

Changing buildbot masters

It's a good idea to let the device run for a while on staging to make sure it is green a majority of the time (compare with production runs).

If you want to move it from staging-mobile-master:9010 to production-mobile-master:9010, do the following:

[root@maemo-flashing production-sd]# ssh root@maemo-n810-XX
maemo-n810-ref:~# cd /builds/buildbot
# change the buildmaster_host and port to production-mobile-master:9010
maemo-n810-ref:~# vi host.py
maemo-n810-ref:~# cat host.py

buildmaster_host = 'production-mobile-master.mv.mozilla.com'
port=9010
