Re: stlc45xx: open source WLAN driver for N800 and N810
Hi Kalle, The archive for stlc45xx-devel should be open, so you can always check from there what's happening. And if something newsworthy has happened, I can always drop a note to maemo-developers as well. Better to use linux-omap ML .

Re: D-Bus running on ARM Platform (ERROR: Couldn't connect to session bus)
Hi Juha,
On Feb 18, 2008 11:23 AM, Juha Kuikka [EMAIL PROTECTED] wrote:
Hi Trilok,
I found on that it is a compiler problem by reading the assembler it
generates from the C-code. I started suspecting it when a values of a struct
were different on caller and callee.
Problem was caused by a struct copy in the style:
void function( struct foo *parameter)
{
struct foo local_foo;
local_foo = *parameter;
...
}
I had to hastily work around the problem by doing the copy with inline
assembler. Replacing it with memcpy did not help as compiler optimized it
into inline copy as well.
Additionally disabling optinizations in compile (-O0) also fixed it.
I don't remember the GCC version we worked with.
Thanks for the reply. My GCC version is 3.4.6 with glibc-2.3.6. Your
suggested trick to disable optimization worked for me :). So, looks
like my toolchain is buggy somewhere in code generation. Now session
bus is working on board under normal user, and also dbus-monitor
executed from this normal user account is able to connect to this
session bus.
But session bus started from the root account, doesn't allow to
connect clients from the normal user, looks like some permission
issues of socket file, I will check this in more details.
Thanks again for great help.

I believe certain work to make sure that 1) does not have any challenges is planned, but probably it's up to Quim to confirm. :) This what Debian pkg-maemo[1] and armel[2] projects intend to do. Progress is slow but firm, now with hildon-desktop recently uploaded to Debian and armel port in good condition (although still unofficial..). And indeed it's the applications and UI that are the main problem. rant Firstly, one needs a VKB. now hildon-input is mostly open source, but when you have a real distribution, it's a lot more annoying that only gtk2 applications have input. Acceptable, at least we have osso-xterm - Oops no, xterm uses hildon_gtk_im_context_show() to show the vkb, which is only available in maemo version of *gtk+2.0* - what a lovely layering violation. So matchbox-keyboard is currently used, which perhaps isn't as pretty as hildon-im, but atleast it works everywhere. Another common grief in compiling hildon apps with stock gtk is the infamous tap-and-hold menu, which apparently is going to be adapted in upstream gtk in a completely different way. /rant So now there is a hildon-desktop, terminal, network-manager and a vkb. Only such minor details as web browser is missing, and the themes/icons having a funny license. But it just a matter of sorting all pieces together to get fully OSS rootfs built out of Debian to support the basic use cases of internet browsing, email and so on. Once we are the (might take a while since I'm busy ATM), it should be easily adaptable to other portable devices. Hopefully it will also motivate people to work on OSS replacements for the rest of the stuff, IE the initfs and wifi driver. I don't hold much hope for the DSP thou, as long as TI holds it as a proprietary architecture with a proprietary toolchain and bios.. I prefer forgetting the dsp exists and just using the audio codec directly with alsa. On the TI DSP front, I heard several rumors though, which are if becomes true, should be good sign of TI coming along. They should be releasing atleast ARM side Linux kernel bridge driver which communicates with DSP like DSPGateway, along with toolchain on higher end platforms like OMAP2/3. Also there is sign of cheaper OMAP2/3 based boards coming from TI soon.

We have provided an GTK+/X based linux platform to customers running a 200MHz ARM with 32MB of flash and 64 megs of memory and it all works smoothly. The platform, even if not optimized perfectly, fits into less than 32 megs including a desktop environment that has loaded GTK+ into memory. So this leaves already 32 megs for application to use. Ok, so out of 64meg of RAM atleast 32megs remained for other applications to use at run time. What was the approx size taken by GTK+/X libraries on that 32MB flash? For example, doing a VOIP phone, with simple contact list driven UI this is more than enough. One can even add a simple browser, to allow user to login to WLANs etc. Ok. Please note that the screen size is one important factor here. The bigger screen means more graphics etc. Also in some cases X can be more memory efficient than DirectFB, for example. Later uses backbuffers for each window where X is more configurable. In terms of screen, output will be show on the TV using some OSD windows. Like OMAP2 processors support displaying all the graphics windows on TV, like N93. In case of no. of widgets, the main application will have following minimum widgets: 1. Buttons 2. Tab Pages (Tab bar and page associated with it - to form menus for control selections) 3. IP Address 4. wireframe grid 5. playback, preview windows, 6. Scrollable lists 7. Checkboxes 8. Calender 9. Digital and Analog Clock 10. Soft Keypad 11. PIN Login 12. Menus 13. TextBoxes And ofcourse most of the widgets will have suitable icon images on them and probably themes in future. People always say that X is designed for high end desktops, which is of course true. Only that X11 protocol was designed 20 years ago, so the definition of high end might have changed a little :-) Very well said :-). Thanx for the inputs. -- --Trilok Soni ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
DBus with Nano-X
Hi, This message might be offtopic, but as nxxx is heavily using dbus, I thought of posting this question. We are planning to use Nano-X to develop the GUI application, and this main application will invoke the other applications as input selected by user through say TV remote or touchscreen input and it will call the resp. app, e.g. camera capture, playback, logger, io control. We also want to have one layer of application management software in-between the main GUI app and other apps mentioned above to handle inter-process communication. I was thinking of using dbus, instead of developing that management software layer to handle just IPC, but is it feasible to use dbus with Nano-X? Anybody used it before OR will it bring lot of dependencies? -- --Trilok Soni ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
