This page does not yet contain instructions leading to a successful installation of Release 10.1.2 onto an SD card

The gist of the write-up and why it's needed in the 1st place. Perhaps add in ref. to 802SD and why no verbose work.

Before you Begin

Warnings

  • will destroy data
  • ext3fs, not jffs
  • if sd card not partitioned, may require fdisk

Caveats

  • fstab mounts causes yum errors
  • 2nd install takes forever
  • may require OFW intervention for different FS label
  • XO-1.5

Workarounds

  • should be possible to edit …/etc/fstab and …/boot/olpc.fth before phase 3 (post-install)



Requirements

Optional

  • Dev Key
  • activities

Procedure

0: Pre-Installation

Back up your data

Obvious, but bears repeating

Create Install Key

  • format usb key (fat32/vfat)
  • download 852s (os & fs)
  • rename os852.img.fs.zip to fs.zip

Optional

  • copy dev key to / of USB
  • Copy activities to USB (for an unzip-n-go)

1: First Installation

  • shut down
  • eject SD card
  • hold down game keys, press power-on
  • wait; let XO restart to "Name: ___" screen

2: Second Installation

  • Once the "Name:___" screen appears, drop into console
  • /sbin/init 3
  • insert sd card
  • fdisk if you need to
  • format sd card (w/ note re: alt. dev. label)
  • mount sd
  • cd /versions/pristine/852
  • cp ; fir i in {1..##} ; do echo -en "\a" ; sleep ; done [ wait forever (w/ note as to why [gnome apps]) ]
  • mkdir …/home/olpc

3: Grafting optional stuff

USB never removed and autofs shouldn't be a prob. but add note re: unmounting automounts

  • mkdir /mnt/usb
  • mount usb

Dev key

  • cp /mnt/usb/develop.key /mnt/sd/security/develop.key

Activities

  • mkdir /mnt/sd/home/olpc/Activities
  • cd /mnt/sd/home/olpc/Activities
  • cp -rv /mnt/usb/*.xo . ;
  • cp -rv /mnt/usb/*.xol . ;
  • ls -1 | while read i ; do unzip $i ; rm $i ; done

Swapfile

/var/vm? /swap? omit the whole thing?

  • dd if=/dev/zero of=1m bs=1048576 count=1
  • for i in {1..512} ; do cat 1m >> swapfile ; done ; # (w/ note as to why repeat 1MB loops in lieu of `dd... bs=1048576 count=512)
  • mkswap swapfilename

Device Label

nano /sd/boot/olpc.fth

  • rename appropriate line

Overclocking

nano /sd/boot/olpc.fth

  • insert command where appropriate (if so desired)

4: Post-Installation

  • cd /mnt/sd/home
  • chown -r olpc:olpc olpc
  • shutdown -h now
  • remove all devices
  • reboot (w/ note: recommend verbose boot 1st time, normal boot 2nd time)

Troubleshooting

List of "oops"s I came across

What next?

This remainder of this page contains no actionable information.

First Attempt

Failure

  • Failure
    used cp -prv /versions/pristine/852/* /mnt/sd/. (it lit. takes HOURS to copy over); boot yields the following:
FATAL: Module scsi_wait_scan not found.
FATAL: Module scsi_wait_scan not found.
FATAL: Module scsi_wait_scan not found.
FATAL: Module scsi_wait_scan not found.
FATAL: Module scsi_wait_scan not found.


No root device found

Boot has failed, sleeping forever.

Observations

  • Noticed that OFW looks for root=LABEL=OLPCRoot or somesuch, and my SD was formatted mkfs.ext3 -v -L OLPC-SD (oops?).
    • Maybe editing /boot/olpc.fth with µemacs in OFW?
    • Manually specifying kernel arg/root dev. in OFW (until "in")?
  • Penguin, not OLPC logo, shows in corner of screen... oopsie or intentional? [ shrugs shoulders ]

Post-Mortem

  1. Boot into OFW (note: make sure to mention developer key required)
  2. emacs sd:\boot\olpc.fth
    • BTW, didn't it occur to anyone that there isn't an F5/F6/F7/F8 key on an OLPC keyb? ^X^S won't work, and I can't tell which button/key I'm pressing!
  3. Down near the end - look for the last screenful:
" nand"  dn-buf count  sindex 0>= if
   " root=/dev/mtdblock0 rootfstype=jffs2"
else
   " root=LABEL=OLPCRoot rootfstype=ext3"
then
  1. Switching root=LABEL=OLPCRoot to root=LABEL=OLPC-SD (note: maybe tell people to mkfs.ext3 -v -L OLPCRoot instead of editing a posteriori w/ dev key)

Second Attempt

Failure

Observations

Looks like a total hang, but no "I give up" message on screen, so sipping coffee and pondering next move... (SD card busted? 10.1.2 not expecting to boot off SD? Can I fsck from withing OFW?)

Post-mortem

OFW doesn't seem to have fsck, so...

  1. Restarted from 10.1.2 on NAND
  2. /sbin/init 3 in console.
  3. fsck.ext3 -v /dev/mmcblk0p1 returned OLPC-SD: clean, 43246/981120 files, 353740/3922425 blocks.
  4. fsck.ext3 -fv /dev/mmcblk0p1 found a problem with inode 13 - fixed (please let that be the reason)
  5. shtudown -r now

Third Attempt

Apparent Success

Greeted with "Name:_____" screen .o0( "I'd like to thank my momma and Elvis..." )

Observations

Boot was kinda sluggish (part key generation, part olpc-configure note: doing a mkdir -pv /mnt/sd/home/olpc after copying to /mnt/sd is imperative), and was done with √ held down - time to take off the training wheels

Post-Mortem

  1. shoutdown -h now, sip some more coffee, and boot without any "cheat codes".

Fourth Attempt

Observations

Something's wrong: Boot screen stuck at one dot for a long time, then blank console with blinking cursor; no command prompt, no response to keyb input.

Post-Mortem

Forcing a poweroff, waiting, and trying again w/o cheat codes.

Fifth Attempt

Apparent Success

Boot sequence looks normal (I'm gonna hafta get used to seeing "sugar labs" in the lower left). One more poweroff, another coffee, and I'll confirm success in a few minutes (I hope)!

Sixth Attempt

Successful

Boots on its own while on battery :-D

Observations

  • Boot animation seems to be much faster than before
  • Wireless network colors are different than in 802.
  • Still can't get used to having to scroll horizontally so see control panel options.
  • No activities (no surprise - see [[1]])
    • After DLing activities, all icons went blank and had to three-finger Sugar

Post-Mortem

¡GOL!, but where's "Restart"??

Seventh Attempt/Second Confirmation =

Sugar, GNOME, and console all work... High-fives all 'round, smoke 'em if you got 'em, and I'll start writing the how-to asap.

Next Steps

  • Fix YUM problems (Why on Earth are /var/cache/yum, /var/tmp, /var/log being mounted as devices?!? Because /etc/fstab said so - YUM won't work with the mount to /tmp - comment the lines out in fstab)
    • Install WINE, TeXLive, GCC, and a few non-free YUMmies
  • Swap space (512MB, probably)
  • /etc/motd
  • Setup SSH...
  • And why can't I shutdown or restart from GNOME? And why can't GNOME end a session cleanly (read: go back to sugar)? And where is the battery monitor for GNOME? And why the bleep can't I shutdown or restart from GNOME??
