GNUtoo's blog

Lots of things happened, That made me forget to update The blog:

FSO/SHR:

• After porting GNU/Linux to the HTC Dream(with mickeyl,and leviathan) I’ve nearly abandoned that port(altough it remains supported by replicant),it has driven me crazy (think about debugging an alsa driver without prior knowledge of alsa, combined with the lack of serial cable(so no kgdb) ) : two blockers persist: wifi and bad quality alsa driver, tough wifi may be solved by Alex[sp3dev] for another device. I also made some GUI improvements.The keyboard is also now upstream in x-keyboard-config.
• Instead I concentrated my efforts on the nokia N900, Now thanks to mrmoku,mickeyl and me we have the modem that is now capable of registering to the network using the new implementation that has more parts in vala. It is also capable of modem forwarding thanks to PaulFertser  and me, I also did some userland integration work and some small kermel work
• for a short period of time I also made some fix for the openmoko freerunner(speed improvements, fix an  accelerometer program with someone on irc(eliza42))

Replicant:

• I ported replicant to froyo 2.2 branch, we also now have an SDK that compiles thanks to paulk on irc(he did most of the work,thanks a lot).
• I also ported replicant to the nexus one. It was only possible because I bugreported to AOSP(android open source project), and that someone told me how to fix a nasty graphic bug.

Buglabs:

• I wrote some applications for the bug 1.x
• I started porting the bug 1.x to openembedded and I also started porting it to the mainline kernel, I did a patch for adding the bug 1.x mainline and it got accepted(although for now there is only the serial port). The nice part was the debugging: with addr2line it is possible to know the address of the dmesg buffer, that you translate to a physical address, and then you md it in u-boot. Practically speaking with that technique you can see dmesg messages from uboot after rebooting the device, making it possible to see dmesg without the serial port initialized in the kernel(handy for writing the serial port platform driver “description”)
• I got a bug 2.0 and I am doing a lot of work with it(adding support for it to the stock openembedded,porting the EMF detector, obtimizing navit for its small screen, having fun). Hardware wise it’s a lot better than the bug 1.x because the hardware is a lot less buggy: while I couldn’t recommend the bug 1.x to the people and had to say that it was great but that the hardware was really problematic,there is no such problem anymore for the 2.0 version. Although the price is still high.

Trisquel:

• I’ve abandoned Gentoo and now run trisquel, for several reason: The first is that there wasn’t a clear separation between free and non-free software in gentoo, the second is that because I’m always cross-compiling something, I don’t have the machine time to compile the computer’s packages. I’m now mostly happy with it(now that there is mplayer in it), I have nearly no issues with it(I’ve ath9k wireless card so my wireless is supported), tough there is no 3d with recent ati cards, because they didn’t release the microcode/firmware source code.Also There are always some minor software bugs. I’ve even backported a patch for it that fixed youtube in totem and that went in trisquel.I didn’t choose gnewsense because trisquel has more recent packages,tough I may switch to gnewsense in the future since it is based on debian.

By the way, I’ve a new blog, I imported all the content from the old blog.

I’ve finally got the touchscreen working on the htcdream…
It consist of a rebased refresh patch for the lcd that is not from me and another patch(that is from me with pointers) that transform the touchscreen in a tslib device. The patches are against the 2.6.29 kernel
It works flawlessly with kdrive and should work with xorg if someone try…
We have touchscreen and usbnet working,we now need:
*telephony(the fso framework works but not shr’ophonekitd)
*alsa(in qualcomm’s kernel)
*wifi(in 2.6.31 kenrel)
*maybe gps,camera and compas
*there is also a 3d chip but I don’t know if the specifications are available somewhere….

So now I’m cross compiling the whole shr because I don’t know when the new images will be out…and I need to do that in order to try to fix ophonekitd

I’ve bought a G1 in order to help some people with the task of freeing the device.
We have now a project and it’s name is replicant
There are 2 ways of freeing the device:
* porting a GNU/Linux distribution like SHR on it
* freeing the android stack
I really wanted to do the first thing but ended doing the second because it was easier
Basically I’ve sound and ril working.
Other free things works,but 3d is not working,but it’s usable without 3d,gps doesn’t work yet either
Basically I’ve been inspired and copied a function from playwav2.c to make sound work.
for the ril I added the following into system.prop:

rild.libpath=/system/lib/libreference-ril.so
rild.libargs=-d /dev/smd0

and it worked but I couldn’t receive calls…
aarown pointed me to this that I followed :
http://android-tricks.blogspot.com/2009 … 2119186963
following what “alien” said:
INSERT INTO secure (name, value) VALUES (‘device_provisioned’, 1);
and receiving call works…and a lot more thing is working now(such as all the keys)

In the previous post there was that line:
mdev requires a mounted procfs, not started.
so mdev didn’t start and that made the console appear…
I investigated more and found out that certain devices were not created such as /dev/console,/dev/null and so on…so making mdev.sh create them solved the problem

Sunday, July 12, 2009, 10:18 PM -

Me,mario-goulart(he tried a lot of things that didn’t work…that was really helpful),and otavio(giving good advises) have been working together to fix a problem:
At first when you booted you had init that was killed or something like this,after running strace I found that it was because it had a segmentation fault,every other binaries that used dynamic libraries had the same problem…I started investigating…at a point someone named mario-goulart shown in irc having the exact same problem…I found out that he wanted to do the exact same work than me but with a different router,so we searched the root of the problem together with the help of otavio.
with the help of gdb compiled statically I found the problematic functions.
Then pb_ told me that “if it’s crashing there, it sounds like gcc is failing to inline those functions for some reason.”
And that hint was true…those functions weren’t inlined…
Then looking on the web I found a post about the -Os optimization failing to inline things on the gcc version I used.
Then I removed the -Os switch in the uclibc configuration and it worked…
But then I had a bug that mario worked around(using boot scripts instead of init): init didn’t load the correct runlevel(the runlevel after S wasn’t ran)…so with the help of the openmoko,after some trying I spotted the difference and changed the /etc/init.d/rcS file overwriting it with that content:

exec /etc/init.d/rc S

and it worked…
so here’s the boot log(still using NFS):

it finally booted!!!
I spent a lot of hours looking for that could cause that kind of error:
boot -elf -tftp 168.0.0.2:vmlinux
Loader:elf Filesys:tftp Dev:eth0 File:168.0.0.2:vmlinux Options:(null)
Loading: 0×80001000/3309436 Failed.
Could not load 168.0.0.2:vmlinux: Section would load outside available DRAM
*** command status = -17

the first step was to use the default defconfig…it made the the error go away for the .text section but it would return for another section.

Then I used openwrt’s CFLAGS…and it wotked…

I had to use ELF because the others format wouldn’t load(srecords and binary/raw)

here’s the first boot:

VFS: Cannot open root device “nfs” or unknown-block(0,255)
Please append a correct “root=” boot option; here are the available partitions:
1f00 256 mtdblock0 (driver?)
1f01 3776 mtdblock1 (driver?)
1f02 3284 mtdblock2 (driver?)
1f04 64 mtdblock4 (driver?)
Kernel panic – not syncing: VFS: Unable to mount root fs on unknown-block(0,255)

it panics because I used openwrt’s defconfig that doesn’t include NFS

I finally with help in ##electronics made my serial adapter work
it was a capactior that was connected on pin 5 instead of pin6 of the max3232…
The printed schematics made me make this error because I took the 6 for a 5…but when you zoom on the schematics on your computer you can see that it’s a 6.

I’ll post a howto on openwrt’s wiki soon.

enjoy:

emacs-x11 built sucessfully with qemu-native-0.10.3 that means that they integrated the patches from qemu-arm necessary to build emacs-x11…
I’ll merge my working emacs recipe soon

Thanks to midpath we can now write applications in java-ME+MIDP+C(L)DC
for proprietary phones with a free SDK…but not only…we can also run them on free computers,phones or others devices…
For the SDK the tutorial is at:
http://midpath.thenesis.org/bin/view/Main/PHONE_SDK
For the running the applications on your desktop computer just unpack midpath in a directory,go in the bin folder ,and run midpath-midlet_launcher.sh /path/of/the/jar
if you are on an embedded device:
if you run busybox change the following lines:
if [ ! $MIDPATH_HOME ]; then
MIDPATH_HOME=$(pwd)/..
fi
to:

#if [ ! $MIDPATH_HOME ]; then
MIDPATH_HOME=$(pwd)/..
#fi

if you have cacao change the following line:
JAVA_CMD=java-cdc
in:
JAVA_CMD=cacao

then install cacao,classpath,classpath-gtk and run midpath-midlet_launcher.sh -jar /path/of/the/jar.
you realy need to be in the bin folder since MIDPATH_HOME is set to a location relative to the bin folder

I’ve sucessfully made an chrootfs for the pma430,with openembedded,with a recent toolchain.
As recent glibc require nptl(native posix thread library),and that nptl is avaliable only for 2.6 kernel…I used uclibc(I didn’t try eglibc).
using uclibc also means that you loose the compatibility with all existing applications…so existing applications must be recompiled in order to work with this chrootfs(this is a problem if you don’t have the sources of the application)
so I will have to ask for the sources of the port of mplayer(the author said on his website that he would give you the sources if you write him a mail)

here’s distro config:
#this is a special version of angstrom for legacy (e.g. kernel 2.4) software
# that means:
# * no udev
# * no sysfs
# * no EABI for ARM

require conf/distro/angstrom-2008.1.conf

TARGET_ARCH = “arm”
TARGET_OS = “linux-uclibc”
TARGET_FPU_arm = “hard”
ARM_ABI = “oabi”

#IPKGBUILDCMD = “ipkg-build -c -o 0 -g 0″
TARGET_CC_ARCH = “-march=armv4″
FULL_OPTIMIZATION = “-fexpensive-optimizations -fomit-frame-pointer -O2″
PACKAGE_ARCHS += ” arm-oabi”
PREFERRED_VERSION_linux-libc-headers = “2.4.19″
ANGSTROMLIBC = “uclibc”

and here’s the machine config:
#@TYPE: Machine
#@NAME: PMA430
#@DESCRIPTION: Machine configuration for the PMA430

TARGET_ARCH = “arm”
TARGET_OS = “linux”
TARGET_FPU = “hard”
ARM_ABI = “oabi”

PREFERRED_PROVIDER_virtual/kernel = “linux-pma430″

MACHINE_FEATURES = “kernel24 screen touchscreen hotplug wifi usbhost usbgadget”

the others packages are inside my openembedded repository.
