The Angstrom Distribution simpad ttySA0

Angstrom 2007.12-r12 simpad ttySA0

simpad login:
I can't login to show the interrupts and the content of /dev/rtc ....

What userid and password is valid to login ??

Best regards

Fine .
The bug fix is not only my work, most of it was done by mister_data.

For the password you have to follow the instructions on your simpad screen. You will have to calibrate the screen after this you will be able to give a password for root. With this password you will be able to log in via serial connection.
But be aware the image I created was mainly for debugging the rtc stuff. It is a rebuilt image so there could be some side effects the normal image does not have. I will hand the patch in and ask for a new official autobuilder image.
In the meanwhile feel free to have some fun with this image

Thank you for continuous testing!

Hello mr nice,

first of all thanks to all contributors (you, mr data, florian, woglinde .....)
I didn't look to the screen, only watched the console (Simpad layed on floor face down)....  
Here is the output :

Code: [Select]

after suspend/resume it was "dead" ...

So we need to track down the resume process ....

Ok, with this image [1] suspend/resume should work. Can you please test it?

thanks

Hello mr nice,

just tried the image and suspend/resume was working  

Thanks and have a nice day

P.S.:
Now i can continue on to get WPA running ....
Are the scripts in the image from OE, /etc/network/if-pre-up.d/wpasupplicant doesn't look like the samples on http://opensimpad.org/index.php/HowToUseWPA and raise an error from busybox/sed.

[mr_nice]

Fine, so we can hand in the patches :).

I have to split the knowledge base better. I will do that now.
The WPA howto was written for Familiar 0.8.4. We will collect everything which is device-dependening on opensimpad.org and everything which is independent and related to angstrom will be add on distribution.org . This is not really angstrom-alike because most other devices are documented there as well.

I don't like this approach for the SIMpad because of the following reasons:

a) Distributions become obsolete and unmaintained . Look at SIMpads history. Angstrom is now the third main distribution and I believe that SIMpad may live longer than Angstrom. Then you have to sort out all the device dependent stuff which changed there and recollect it somewhere else. Nobody knows about the recent state and a lot of effort is needed which could be better used to do other things.

b) SIMpad users are a very small community. It would be nice to have a home. Some people maybe don't like Angstrom and prefer something else. These people can still contribute on a site which is distribution-independent and profit from such a documentation.

c) Documentations will split in many different parts which will all get some changes. This is hard to track.


For WPA on Angstrom follow this discription:

Hello mr nice,

so the next autoimage will be ok ...

Thanks for the link, i will read on ...

Thanks and nice evening

Oliver

Simply amazing, it boots like a charm! Thanks a lot for the great work. Now I can at least experiment a bit with that Angstrom distribution and the 2.6 kernel.

I still have to test my various PCMCIA cards, but it looks like lots of strange boot messages have been fixed already.

So what's the next challenge? Getting the sound to work? Will we be able to use that old guy as a SIP phone some day?

[mr_nice]

Nice to hear that you like it .

So what's the next challenge? Getting the sound to work? Will we be able to use that old guy as a SIP phone some day?

2.6.24 misses 4 things:
- sound
- usb
- smartcard
- DECT interface

There is a paper available for a similiar chip. I will try to use it as a base for an ALSA System on Chip (ASoC) driver. But I don't know if I will be able to do it.
There are two different patches available for usb net support one is the old driver ported to 2.6 (look at hh.org kernel tree) and the other is a driver written for balloon. Both are not working without changes on SIMpad. For me USB is not importent but maybe I will find some time...
The smartcard driver should not be that hart to develop but no one is really interested in having it except I.
I really have no clue about DECT.

A good challenge would be to clean up the patches and send them to lkml.

I am currently try to port u-boot to the pad, and I was able to boot Angstrom with it .

What do you think about the current bootldr partions?
Should we switch with u-boot to one big ~31 MB partition and delete the 8MB home?
pro:
- More space for applications
con:
- You have to backup /home befor you flash a new image.
- If you download a to big file to /home you may not be able to boot your device.

I also try to get poky linux [1] build for SIMpad .

mister_data what do you think we should do next?

Well done, the latest test-image (Simpad-2.6.24.rtc-debug-4-image-r12) seems to be working so far, but there is not enough space left on the root partition to install minimo, and without it, it all makes no sense to me, because all I want to do with it, is surf the web.

I tried deleting as many packages, as I thought are not needed for my purpose (like all the bluetooth and irda stuff, GPE package manager, firmware-stuff, kernel-modules for cards not used), but still not enough space left:

Code: [Select]

$ df -h
Filesystem                Size      Used Available Use% Mounted on
/dev/mtdblock1           23.8M     23.5M    304.0k  99% /
tmpfs                    40.0k         0     40.0k   0% /mnt/.psplash
/dev/mtdblock1           23.8M     23.5M    304.0k  99% /dev/.static/dev
tmpfs                     2.0M     32.0k      2.0M   2% /dev
tmpfs                    30.1M         0     30.1M   0% /dev/shm
tmpfs                    30.1M    120.0k     29.9M   0% /var/volatile
tmpfs                    30.1M      4.0k     30.1M   0% /media/ram
/dev/mtdblock2            8.0M      5.8M      2.3M  72% /homeThe minimo package itself has 4.7 MB (but it has two dependencies as well), the old familiar image (which allowed me to install minimo without problem) was 14.027 KB, this Angstrom image has 17.984 KB.

What can be done to make minimo fit in?
What else could I delete / remove?

[mr_nice]

You have at least these options:
-use gpe-mini-browser
-delete your home partition

I wrote this [1] howto about removing your home partition. It requires to reflash the jffs2 image.

happy testing

Thanks, mr_nice, that did the job.
