8.  Devices and drivers

8.1  Wifi (RTL8187B)

The RTL8187(B) is included in linux-libre 2.6.32.9 lemote kernel by default.

It is also included in the lemote git 2.6.27.1 version, but not compiled into this version of the kernel as released with the yeeloong. To enable it, see GnewSenseToMIPSLinux.

Alternatively, download the RTL8187B driver from http://dev.lemote.com/drupal/node/53

Execute:

tar xjpf rtl8187B_linux_26.1051.0116.2009_driver.tar.bz2 -C /lib/modules/2.6.27.1/kernel/drivers/net/wireless

• References: RTL8187B drivers and patches

9.6  Updating of the PMON configuration

On the Fuloong mini, the /usr/sbin/update-pmon script may be used to update the /boot/boot.cfg file.

To this end, execute /usr/sbin/update-pmon and adapt the modified /boot/boot.cfg if necessary, especially if you are using a multiboot configuration. Copy it eventually to the root boot.cfg file as set by the PMON boot firmware (see Boot parameter).

So, in this experiment, the active distribution is located on the /dev/hda2 partition. The update-pmon script updates the local /boot/boot.cfg file located on the /dev/hda2 partition. However, the PMON2000 boot firmware is set to use the /boot.cfg file on the /dev/hda1 partition. In order to make the modifications of the boot.cfg file effective, you should copy it to the /dev/hda1 partition, after updating it according to the other distributions eventually installed on the other partitions.

12.  Emulation

12.1  The gxemul emulator from Lemote

• http://www.lemote.com/upfiles/gxemul-0.4.3.godson.tar.gz

The release 0.4.3 has been improved by Lemote (Liangjin Peng, penglj at lemote.com) and reflects the state of the loongson2e CPU. The newer loongson2f CPU has introduced newer hardware and the gxemul code remains to be adapted according to this new hardware.

Changes in the release 0.4.3 (according to Liangjin Peng)

1. MIPS:loongson2e CPU support added, which is as same as mips10K or other 64bit MIPS CPU.
2. Bonito2E north bridge support added, which is optimized by ICT.
3. 16KB page size support added for MIPS platform, which only supports 4KB before, but still a little bugs in it due to the unflexible architecture of the gxemul.
4. This platform has been ported mainly according to the web page of the gxemul, few documents made for it.
5. Working on the rtl8139 network adapter. This is a work in progress,

and it is still not usable today.

Hardware changes introduced by the loongson2f CPU (according to Liangjin Peng)

1. With the loongson2f CPU, the north bridge has been integrated, causing a little software modification.
2. The south bridge is changing to AMD CS5536, which is more complex to configure, so it will cause a lot of work load to port to gxemul.
3. The video chipsets also differ to mini Fuloong2e, which are smi712 for yeeloong and sis315e for mini Fuloong2f.
4. Mini Fuloong2f has another network adapter rtl8180 inside which also will be a big problem to be resolved.

12.3  The original gxemul emulator

• http://en.wikipedia.org/wiki/GXemul

13.  Remote access to development hosts

Lemote has setup a compile farm of four Lemote mini-PC (fuloong mini).

Ask the login parameter in order to access to this hardware remotely (via ssh).

For the moment, send your ssh public key to sysadmin@gnu.org - preferably in a GnuPG signed email. If you are rearing to go or the request seems to be taking too long, feel free to ping djbclark in #gnewsense (freenode IRC).

To access the main machine, do: ssh -A <user>@dev.lemote.com -p 2200

After login, you can connect to build[2-4] to use other machines, if you have requested and been given access to them.

We should probably modify builder to use ccontrol / distcc to make easy use of the multiple machines.

There is a mailing list for everyone who has accounts: loongson-buildfarm@nongnu.org.

14.  Preliminary work

You may use 2 systems: the build system and the target system (either the Fuloong mini or the Yeeloong laptop)

14.1  Creation of a recovery system for the Fuloong mini

Reboot from a rescue kernel

Download http://dev.lemote.com/files/resource/download/rescue/rescue-fl

Load it via usb:

load /dev/fs/ext2@usb0/boot/rescue-fl

Reinstall the whole system

To reinstall the whole machine, just put the whole V1.1.x directory (http://www.lemote.com/upfiles/8089_OS_v1.1.1/ ) into a usb stick or disk (first ext2/3 partition, root directory), then use the 'recover' function of the pmon(press tab key during boot up).

1) I downloaded the new version of the os that samy talked about in the mailing list.

2) Formatted an usb key ext2 and put it all inside.

3) Inserted the usb key BEFORE switching on your Lemote Yeeloong.

4) At the pmon boot I pressed del.

At PMON> prompt I wrote:

boot /dev/fs/ext2@usb0/vmlinux

and again a second time:

boot /dev/fs/ext2@usb0/vmlinux

5) The lemote will display a chinese writing and below it, "System is recovering and Please wait for several minutes", then it will reboot.

6) When it rebooted, the kernel didn't load (maybe this was a particular issue related to my situation) so I set again the pmon variable called "al" (autoload):

set al /dev/fs/ext2@wd0/boot/vmlinux

7) The Lemote Yeeloong will then boot automatically into the new updated os.

gNewSense mips-l from an usb key

• Reference

http://lists.gnu.org/archive/html/gnewsense-dev/2009-02/msg00026.html

http://lists.gnu.org/archive/html/gnewsense-dev/2009-03/msg00024.html

• Netboot image

A netboot image can be obtained from:

http://archive.gnewsense.org/gnewsense-mipsel-l/netboot/

• Procedure
  - Put vmlinux and initrd.gz in a USB disk (in the example I used ext2)
  - Get to pmon2000 prompt and type:

     load /dev/fs/ext2@usb0/vmlinux
      initrd /dev/fs/ext2@usb0/initrd.gz
      g console=tty no_auto_cmd

  - Follow installation process in D-I.

- Once finished, your system can be boot with:

      load /dev/fs/ext2@wd0c/boot/vmlinux-2.6.27.1-libre-medan
      g console=tty no_auto_cmd root=/dev/hda3

    (assuming you installed to third partition of the internal
    disk, otherwise you'll have to change wd0c and hda3)

    And you can make this the default by setting "al" and "karg"
    variables.

Post-installation step:

apt-get install gnewsense-pkgsel-desktop

If you got an Xserver error, then modify the /etc/X11/xorg.conf configuration adding:

 Section "Device"
        Identifier      "Configured Video Device"
        Driver          "fbdev"
        Option          "UseFBDev"              "true"
 EndSection

Alternatively, install the xserver-xorg-video-siliconmotion_2.2.8-lemote.r03_mipsel.deb (see http://dev.lemote.com/drupal/node/49) and copy a xorg.conf from another working yeeloong installation.

gNewSense mips-l from a tftp server

• On the server :

- install and setup a tftp server (for example atftpd)

- copy the files initrd.gz and vmlinux from http://archive.gnewsense.org/gnewsense-mipsel-l/netboot/ onto /var/lib/tftpboot

• On the installation target (Yeeloong)

- boot the Yeeloong

- press DEL

- At the PMON> prompt type

ifaddr rtl0 <addr.of.your.laptop>
   # to set the ip address of your Yeeloong, e.g. 192.168.1.31
load tftp://<addr.of.your.tftp-server>/vmlinux 
   # to load the kernel image on your tftp server, e.g. 192.168.1.30
initrd tftp://<addr.of.your.tftp-server>/initrd.gz 
   # to load the initial ram disk image
g console=tty no_auto_cmd
   # to set the console

Follow the installation procedure in D-I

14.7  Upgrade of the PMON boot firmware

work in progress

CAUTION: if carried out incorrectly, the upgrade of the PMON2000 firmware can brick your unit and require a reprogramming of the memory! Be careful!

The upgrade procedure of the PMON2000 boot firmware through software control path:

1. When the yeeloong or fuloong machine power on, press DEL to enter the PMON console.

2. Type the following command to upgrade the firmware

load -r -f bfc00000 method_to_load_pmon_binary_image

When this command is completed, a successful message will output to the display.

CAUTION: This command will damage all the data in the firmware, if wrong data has been writen into it, the machine will do never run up unless taking the firmware off the motherboard and writing correct data into it through the programmer.

Choose a method to load pmon binary image: either using the ftp network protocol or using a local or removable storage unit:

a. Using the tftp network propocol.

Example:

load -r -f bfc00000 tftp://host_ip/pmon-new-image.bin

Prerequisite: the machine must be assigned a static IP

To this end, enter the pmon console, and type the command:

ifaddr rtl0 ip_address

b. Using a local or removable storage.

Example: if the pmon image is located on the first partition of the local hard disk (wd0):

load -r -f bfc00000 /dev/fs/ext2@wd0/pmon-new-image.bin

or, if the pmon image is located on an usb stick (usb0):

load -r -f bfc00000 /dev/fs/ext2@usb0/pmon-new-image.bin

3. Reboot your machine. Your machine will boot from the new firmware.

Note that if you have problems booting from wd0 after you do the upgrade, you should try booting from usb using a rescue linux, and do from it:

fsck.ext3 -fy /dev/hda1

Where /dev/hda1 is the ext3 partition that your vmlinux is on (alhough you might as well just do this for each of your ext3 filesystem partitions). Either many people interrupt the boot process in the wrong place, thus causing some filesystem corruption, around the time they do PMON upgrades, or newer PMON versions are more sensitive to filesystem corruption than older versions.

Images

• Version 1.3.7 (build date = 2009-02-06) (WARNING: This version makes booting from wd0, the internal hard drive, not work on some systems. Booting from usb0 still works, and upgrading to 1.4.3 fixes the problem.)
• Version 1.4.3 (sha1sum dfe3302b202a538b3b7c6ade804ef7ccc3903f1a - translated announcement)
