OLPC Firmware Release q2e43 - 2010-05-13

Download: q2e43.rom

This release fixes bugs that were found during testing of q2e42. It is a candidate for widespread release, pending another round of testing.

Changes since OLPC Firmware q2e42

• svn 1792 - Add word ops to ec-cmd - Allows testing of new 16-bit SCI operations.
• svn 1790 - Force serial numbers to upper case in the security code.
• svn 1789 - OLPC trac 10123 - delay before starting touchpad test so users can see previous messages.
• svn 1788 - FAT filesystem driver - fixed a problem with free cluster tracking in the case where the number of free clusters is set to "don't know".
• svn 1786 - Libertas WLAN driver - stop adhoc when closing the driver.
• svn 1784 - OLPC trac 10118 - Increased the size of the security line buffer for delegated leases.
• svn 1782 - OLPC trac 10056 - OFW test-all and laptop self test no longer tests WLAN or internal SD. test-all wasn't testing *anything* after doing the suspend/resume test, due to a reentrancy problem in scan-subtree. The resume code was using scan-subtree to fixup some USB state, and that was clobbering a variable used by the higher-level call to scan-subtree in test-all. (This problem only showed up on XO-1.5, but the fix is in core code that is also used by XO-1.0)
• svn 1781 - Add DS2756 EEPROM recall all banks command to batman
• svn 1779 - Sync OFW batttery error info with EC
• svn 1776 - Improvements in battery status display words.
• svn 1775 - Use -O3 for compiling the inflater, thus making it run 2.5x faster.
• svn 1771 - Libertas WLAN driver improvements for adhoc multicasting.
• svn 1766 - Fast code implementations of interrupt controller handling words.
• svn 1764 - SDHCI driver - fixed problem introduced by r1740 - incorrect wait for completion after erase-blocks.
• svn 1759 - OLPC trac 10022 - Power wait must happen before turning off the EC, otherwise you can't read the AC and battery state.
• svn 1758 - OLPC trac 10043 - Fix USB keyboard operation for XO-1.
• svn 1757 - OLPC trac 10022 - XO 1.0 Keyjector - power state check before bootfw2.zip
• svn 1756 - OLPC trac 10029 - build XO-1 firmware with real keys, not test keys.
• svn 1754 - OLPC trac 10025 - sound-recording plays back in doubletime.
• svn 1753 - OLPC trac 10028 - OFW reprompts on glob copy to ext2 file system
• svn 1747 - OLPC trac 10024 - restored progress icons for internal NAND/SD and external SD storage.
• svn 1744 - OLPC trac 10024 - Improved SD card detection procedure so it works well for both the CaFe SDHCI controller and the Via SDHCI controller.

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 C2, 256 MiB memory installed, S/N SHF7250024D
 OpenFirmware  CL1   Q2E18 Q2D
                     ^^^^^

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.

Beginning with firmware Q2D08, you can see the firmware version in secure mode by powering up with the "check" game button held down.

Beginning with OS Build 690 (or less?) you can also go to the main 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

• download the firmware from http://dev.laptop.org/pub/firmware/q2e43/q2e43.rom and save it to a USB drive or SD card,

• shutdown the laptop,

• 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:\q2e43.rom

• if the downloaded file is on an external SD card:

 flash sd:\boot\q2e43.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,

• start the Terminal Activity and type:

su
cd /versions/boot/current/boot/
wget http://dev.laptop.org/pub/firmware/q2e43/q2e43.rom

• shutdown the laptop,

• 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\q2e43.rom

• if the file is on the internal SD card of an XO-1.5 or XO-1.75:

flash int:\boot\q2e43.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.

• shutdown the laptop,

• 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\q2e43\q2e43.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.
