OLPC Firmware Release q3a25

q3a25 fixes secure filesystem update and tweaks a lot of things related to manufacturing tests.

It works on XO-1.5 A1, A2, B1, B2, B3, and C1 systems, but does not work on any XO-1 machines.

Download: q3a25.rom

Open Firmware is svn 1624

Changes since q3a24

  • svn 1626 OLPC trac 9887 - added suspend/resume test to memory selftest.
  • svn 1625 Via manufacturing scripts - extra messages after restarting a failed runin.
  • svn 1624 Via manufacturing scripts - added option to restart a failed runin.
  • svn 1623 Via manufacturing scripts - Added auto-firmware-update to the assy script.
  • svn 1622 Via diagnostics - don't fail the camera test if serial is preventing it from running.
  • svn 1621 more changes for initial production
  • svn 1620 SD driver - write-blocks-end was leaving an extra 0 on the stack, causing fs-update to mess up Command: in assy.fth
  • svn 1619 factory.fth - check for preexisting request file and report the problem.
  • svn 1618 Fsupdate - check for output device too small for image and for zblocks line mismatch.
  • svn 1617 Via manufacturing tests - further eliminated the second call to NTP during .clocks.
  • svn 1616 SNTP - added data format commentary to the source code.
  • svn 1615 TCP - changed local port number assignment to use the IANA recommended range. Also added a local port number assignment method for UDP.
  • svn 1614 Via manufacturing tests - Set MD tag from RTC not NTP, thus avoiding multiple NTP queries.
  • svn 1613 Via manufacturing tests - fixed stack cleanup error in runin.fth:handle-tag
  • svn 1612 Via manufacturing tests - corrected error in clock display, commented out call to "verify-rtc-date" until factory NTP servers get synced, reordered "warning !" vs "device-end" for proper nesting.
  • svn 1611 OLPC trac 9882 - updated help command for XO-1.5
  • svn 1610 OLPC trac 9873 - fixed secure reflash.
  • svn 1609 TCP - randomize local port numbers to prevent reuse.
  • svn 1608 HDaudio selftest - fixed channel format problem that was causing low volume for speaker playback test.
  • svn 1607 remove reference to DL tag, clarify Command: description
  • svn 1606 OLPC 1.5: Override the final LCD tests with this until we change it in the firmware
  • svn 1605 USB keyboard - clarified error messages and suppressed the "Failed to set idle" message since it is not critical.
  • svn 1604 Via manufacturing tests - if scanner needs to be plugged in after booting, call ?usb-keyboard to hook it into the console mux.
  • svn 1603 x86 kernel - increased return stack and data stack sizes from 256 to 512 cells, thus preventing return stack overflow into the data stack on deeply nested fcode interpretation scenarios.
  • svn 1602 fixed final tempfile generation. also added ?usb-keyboard call to try to pick up freshly plugged scanner.
  • svn 1601 Changed the IP address in the ka-dir$ value.
  • svn 1600 Via manufacturing tests - the NTP/RTC comparison code was horribly broken. Also changed the IP address in the ka-dir$ value.


EC code is version 1.9.18

<Same as q3a24>

WLAN firmware is 9.70.7.p0

<same as in q3a14>

Which Firmware Do You Have?

If your machine is not in secure mode, the firmware version is displayed in the startup banner, as in:

 OLPC XO 1.5, 1 GiB memory installed, S/N SHF7250024D
 OpenFirmware  CL1   Q3A04 Q3A
                     ^^^^^

If your machine is in secure mode, you can go to the Terminal activity and type

 cat /ofw/openprom/model

If your machine is in secure mode but the OS will not start, just go ahead and try to upgrade the firmware anyway. The procedure is safe and will not do anything if you already have up-to-date firmware.

You can see the firmware version in secure mode by powering up with the "check" game button held down.

You can also go to the main Sugar screen, click on the little man and select "about this XO"


Installation

When installing new firmware, you must have a well-charged battery and the AC adapter plugged in. The firmware update code will not proceed otherwise. Possible error messages are:

error message how to fix
AC not present plug in the power cord, check the battery LED is on, then try again.
No external power plug in the power cord, check the battery LED is on, then try again,
No battery plug in the battery, check the latches, then try again, or try another battery,
Battery low allow more time for the battery to charge, then try again, or try another battery.

Unsecured Laptop

This section is for unsecured laptops. Most XO-1.5 and XO-1.75 laptops are unsecured. Most developer XO laptops are unsecured. To unsecure your laptop, follow the instructions at Activation and Developer Keys.

You may install using either:

  • a USB drive or SD card,
  • the laptop's internal drive,
  • a network.

Choose one.

Using a USB drive or SD card

  • check the battery is inserted and locked,
  • check that the power cord is in place and the battery indicator is green,
  • insert the USB drive or SD card,
  • turn on the laptop, and get to the 'ok' prompt. See Ok for more detail. You should see:
ok
  • if the downloaded file is on a USB drive, type:
 flash u:\q3a25.rom
  • if the downloaded file is on an external SD card:
 flash sd:\boot\q3a25.rom
  • wait for the laptop to reboot itself,
  • remove the USB drive or SD card.

(Expert users may remove the USB drive after the message "Got firmware" ... at this stage the file has been read and closed.)

Using the laptop internal drive

An alternate method is to download the firmware file to the laptop internal drive and then install from the internal drive.

  • start the laptop,
  • connect to a wireless or wired network,
su
cd /versions/boot/current/boot/
wget http://dev.laptop.org/pub/firmware/q3a25/q3a25.rom
  • check the battery is inserted and locked,
  • check that the power cord is in place and the battery indicator is green,
  • turn on the laptop, and get to the 'ok' prompt. See Ok for more detail. You should see:
ok
  • if the downloaded file is on an XO-1, type:
flash n:\boot\q3a25.rom
  • if the file is on the internal SD card of an XO-1.5 or XO-1.75:
flash int:\boot\q3a25.rom

Using a network

You will need a compatible USB to ethernet adapter, or an open or WEP wireless access point, connected to the internet.

  • check the battery is inserted and locked,
  • check that the power cord is in place and the battery indicator is green,
  • turn on the laptop, and get to the 'ok' prompt. See Ok for more detail. You should see:
ok
  • if using wireless, type the essid of the wireless network:
essid mynetwork
  • if using a WPA wireless access point, type the WPA key for the network:
wpa passphrase
  • type the flash command using the download link above, but change all slash characters so they are backwards, for example:
flash http:\\dev.laptop.org\pub\firmware\q3a25\q3a25.rom

Secured Laptop

Secured laptops can only use flash firmware that has been signed. All mass-production machines had the latest firmware at the time of manufacture.

Upgrading firmware describes how to upgrade to a newer signed firmware release.
