Executing file from flash-card immediately after booting..?

Hey people on the board!
I'm a relative newbie in this PDA-stuff so I have a question which perhaps (hopefully) is easy to answer. Problem:
I have an application which I run on my Qtek 1010. The application runs fine, but prior to using it, a significant amount of time must be spent on installing and configuring it. In case of battery-faliure, this needs to be done from scratch. I would therefore like the Qtek to execute a script-like file (autorun.exe) which performs this task, immediately after booting.. The file is present on a flash-card inserted in the slot. How do I do this? Where - on the card - do I place the file? In the root? And how do I detect it and run it automatically after a cold-boot?
Any help would be greatly appreciated! Thx!

Its quite simple
Hi there, your problem to fix is quite easy.
If you look in in your windows directory with the built-in explorer, you'll find a directory - either "startUp" or "Autostart" depends on the system language you are using. Here you put a link to the program you're having on card. With every cold- or warm boot it will be executed. :lol:
regards
cimber

On the memory card make a directory named 2577, I believe the pocket pc will look here for your autostart on boot, try it and see. You can try putting a cab file in there or your autostart config file. I am not an expert in this but thats how its done with ipaq navigation system which is an automatic routine using the 2577 directory and I have also seen other software using the same method.

the file should be called 'autorun.exe' in the '\storage card\2577\' directory.
when you insert the card, the autorun.exe will be copied to \windows, and executed with 'install' as parameter.
when you remove the card, it will get executed with 'uninstall' as parameter.
and then removed from \windows.
but this will not nescesarily happen at boot.
just figured out another thing: the number you put in the .lnk file in \windows\startup is completely ignored by windows.
also, if the executable is in \windows, you may omit the path,
you may also omit the extension if it is .exe.
if you specify commandline parameters, your application will get passed upto 255 characters starting from the first non-whitespace character after the executable name.and including any newlines that may be in the file.

Hi!
Thanks for the response. I'll give the methods a try during the day and get back.
Thanks so far - I appreciate it

Hi there (again)!
I have tried the different suggestions with no luck. Perhaps I should have been a bit more specific. What I actually need is to have the autorun.exe run (install) a number of cab-files also on the flash-card. I was - perhaps naively - thinking that there would be a generic tool out there to create this type of autorun.exe file? I am looking for something along the lines of what is being done here:
http://forum.xda-developers.com/viewtopic.php?t=508&highlight=autorun
Only, in the case above, the autorun.exe lauches a specific .cab-file which contains a ROM for the PDA.
Is there a "configurable" .cab-installing autorun.exe out there somewhere? Or should it be written from scratch every time for new purposes?
Hope I make myself clear
/Joe72

yes, it is in the extended rom, processing the config.txt file.
eeeh, but the location of the config.txt is taken from the registry, which is currently always set to \extended_rom\config.txt.

Could you explain that to me in more detail, please? As I mentioned, I am a relative newcomer in this Xda stuff Thanks..
/Joe72

what you are asking for is the autorun.exe found in the extended rom,
look for 'extended rom batch language' on the forum for details.
problem is that the autorun.exe from the extended rom uses the config.txt
pointed to by the "[HKEY_LOCAL_MACHINE\Comm] AutoRunCfg" registry value. which always is '\Extended_ROM\Config.txt"
what you could do, is change the 'autoruncfg' string in the autorun.exe binary in to something else. and then fill your own config.txt path in that registry value.

Thanks - that sounds like the way to do it. I guess I would copy the original config.txt, add my .cab-files, put it on the flash-card and then change the key in the registry to point to the card. Is that how it would go?
Now another stupid question: How do I access the registry? There is apparently no regedit.exe like on my desktop?

Managed to access the registry using Windows CE Remote Registry Editor. But whooops.. After a cold boot, the registry is reset to factory settings?! Hence my changes of the path to config.txt are also lost..? What to do?

Creating a ROM Image for ATnT Tilt

I have been working on a project to insert debug messages in low level dlls [like coredll, ws2.dll] and so on. The testing so far was done on device emulators and the .nb0 image seems to be pretty stable on it now.
Where I need help from xda community is how to take the next step - how to generate a ROM image for my kaiser. Specifically what all build options should be specified to my platform builder to get the right image for my device.
I tried to search previous postings for help but could not find one - may be I did not search thoroughly. My apologies if I did not search thoroughly - if it has been discussed in the past - would be great if someone could point me a link to it.
Thnx

TPC and myself has kitchens available for download. Pick one and replace your files, and build ROM.

To be precise - download a kitchen from here?

Thnx for helping .. have a few hickups setting the ROM up.
1. Downloaded http://m-s-j.net/tpckitchen/kitchens/TPC_KITCHEN_6.120146.7z
2. Doing a build_rom.bat results in the following errors
Failed to set data for 'htcrt_backup'
"There is no device found to meet your project configuration. Try to update your devices file with new one."
"Access Violation - read at 000000"
Do I need to setup some config file somewhere - do we have a README for the process?
3. I dont quite understand the point "replace your files, and build ROM."
I have changes done to coredll and ws2.dll which were compiled using the 'emulator' flag in platform builder
a. What compile flags should the I use before I copy/paste my dlls into the kitchen
b. In the current kitchen - coredll is a directory containing 5 files S00 to S04 and also contains imageinfo files. Do I put in my coredll.dll file? or is there a step in between?
As you could see from my questions, I am complete newbee in building ROMs for phones - would appreciate any help from the community
thnx

I guess you're using Vista, right? It did me too. There are two (three?) solutions:
1. Disable UAC
2. Ignore it and via htc rom tool build .nbh by yourself (click right -> run as administrator on TOOLS\htcrt.exe) - OS.nb is in TMP directory
3. (not confirmed) Run the build script via cmdline manually, AFAIK TPC has got it written somewhere there.

this is not the right place to be asking this, if you have questions about my kitchen you need to look in my kitchen thread. you will find the answers to your questions have already been posted there and if you need more help ask there and we will help you.

Project: apk2

hi folks!
i'm not a developer but sometimes i do some scripting.Now i'm working on a project that called "APK2",and i think that could be useful!
Some months ago, I thought "why don't create a package manager and a package system to install real linux packages, and not just apps? I may want to install some command-line tools to run with terminal emulator" then I wrote this script, named apk2.sh, that installs some particular packages (I wrote another script to easily create this type of packages): he simply does the apt-like un-tar in /, but it installs a config directory too, to remove the installed packages.
It supports the preinst, postinst, prerm, postrm scripts too.
Tell me if it could be interesting, and I'll put it here.
If so, I need testers
If not, simply tell me, and I give up.

so could you be able to run like air crack through debian with this or?

I could be able to run it on Android if someone can port all the libs to armv5e
I know, you have to do the porting in order to run it, but for example if there is the package for debian armv5 I think it should work if you take all the deps from the repo (may need some repacking, just to remove the CONTROL folder, and maybe to add the file needed to uninstall and various preinst, postinst etc. ).
And you don't need to run a debian or an ubuntu on Android, that's not really fast.
What do you think?

i think that this sounds really good and if it worked fully it would be a major addition to android development im hoping youll continue with this

Thank you!
Any tester? I attach the scripts to now how apk2 works, just run it without any parameter, and it will show you
The other script it's simple to use, you just have to run it once to create in your home the basilar directory tree, you have to complete it and put the files in it, then you just have to put your preinst-postinst-prerm-postrm scripts in the ~/yourpackage/system/etc/apk2 directory, if you have some.
Then run the script again, insert the same package name, and here we are! The package is build! It's in the packagename directory in your home, in .apk2 and in .tar.gz, if you have to edit something do it on the tar.gz, and then change the extension in .apk2
PS: rename the files *.sh.txt into *.sh, because this forum doesn't allow .sh attachments...

i.e., the one olvap377 mentioned: air crack (I think it's possible).
or, we can run every app that does not need X server.
I created some demo packages (containing 2 scripts), one is SwapTools, and lets you enable/disable swap with 2 simple cmds (swap-enable and swap-disable); at the first run it collects some info, like the swappiness and the swap partition, then it saves the conf in a file (using swap-disable with --remove-conf will remove the conf file).
Another one I created is remount: you can remount your /system partition rw or ro just by typing on a terminal emulator
Code:
remount rw
or
Code:
remount ro
But you can try to use other appz compiled for armv5 processors, like all the debian apps, except for the one with GUI (we run on framebuffer, no X server :/ )
PS: I attach the pkgs, I added the .zip extension, just rename it in pkgname.apk2

Honest question: Why reinvent the wheel? Other embedded Linux projects have used ipkg to good effect, or its close relative opkg (refs from same link) which is used by Openmoko. A port of this to Android systems which have uClibc should be nearly trivial.

I have also an Openmoko phone
I know very well ipkg/opkg, it could be interesting a porting, but I thought it was better to create a little lighter script to do it, because 1. a script that uses sh is usable in every system, you can either to install armv5e pkgs, or any armv* pkg, you have just to change some little things; 2. I don't know how to port, and I'm not able to do programming.
If you are interested and know how to do a porting, it could be very useful, because opkg has really lots of functions...
I just did what I could

Ahh, okay, I see what you mean. Fair enough; I haven't seen your work so far, I was just concerned you were doing unneeded work. 'Course sometimes it's good to do that for the learning experience.
I don't have a full build setup for Android, so I can't recompile (I do have a full build setup for building Optware packages, but that's not quite the same), but I believe most custom ROMs ship uClibc. I'm not familiar enough with uClibc to know if you need to build against an exact version, though you could copy opkg from your Openmoko phone for the heck of it and see if it runs

Ya mean, copy the binary??? If so, it won't work of course, because the architecture of the openmoko processor is armv4t, it wouldn't see my binary
Nethertheless, if someone is interested

Hi I have and HTC Hero from Sprint, I'm not a linux power user but I spent lots of time in my computer running Ubuntu just for 2 big reasons 1 freeware and 2 it has the best an simplest packet manager... I love deb files that installs like any .exe win programs I love that! I'm son not a coder and have little to no skills under Linux shell I use my sudo nautilus commands and so because I need it but I hate to untar or tar gz crap... for me that it old and useless some linux power user may get offended by that comment but hi times changes we love GUI... if you manage to post prints screens or a word open office or PDF documentation dummy proof I'm very up to be a Happy tester... the other thing I'm a Digital Graphic Designer if you need some design for a GUI and can try to help you in making and eye candy app...
Here it the way I will love to see grow this project... finding a way to installed it as an apk file like others in the android market so users can install the app easy then...in top of that a simple GUI to browse to the SD card in order to get the apk2 file... you where talking about not being able to run programs that has GUI that it is sad but still interesting but a lot of work to do without a good community because that means that all GUI may need to be re-design to the different resolution on the phones and be touch friendly...
I'm not sure if I'm helping at all but I love the big picture behind your project...

I'm porting opkg on Android, but i'm can't tell that's a trivial task )))
i also wrote simple howto "building and porting linux apps for android from scratch", but on russian. If needed i can do some translating and put here too.
Also may be we can open project for buildroot-like framework for android and opkg's repository. In my how-to i'm use crosstool-ng + gcc + uClibc.

Wow! Please do some translating!
But, when you finish the porting, how will you manage to port the packages?
Will you use the debian pkgs changing the extension? Would it work?
Thanks a lot!

No, we want to create only android repository of packages, based on opkg (ipkg)
for arm, mips and others platfofms.

Hello, Walter, and thank you for sharing this.
I´m fighting with my Elfin but I think Rhobuntu needs at least 1,6 GB of free space in the SD card.
So, with my 1GB card, I think I´m sold .
Greetings.

I am using HTC TOUCH GSM.
I have installed the Rhobuntu.
It opens up till the main screen and hangs..
no pointer movement and the screen resolution is too small..
I am not even able to scroll and see the full screen.
It hangs ..
need help..

i tried it but its mere of a beta stage

Let´s try
Thanks!!!

Hi Walter, wheather it will work with HTC TOUCH GSM???

I have the same problem after starting the desktop and the icons bar on the botton, the device show the keyboard but I'm not able to move the cursor with the stylus.
please note that the device shows me only part of the keyboard, seem like that the resolution is wrong.
During the startup the font changes size. can be related to the wrong resolution??
No actions can be done with the sistem.
thanks and let me know if more information is need

This thread made me come up with a new prefix for these threads.

So put [LNX] in threads for Non Android Linux builds. So users can easily identify or search for specific threads.

I tried with a live ubuntu, but it did not work. I tried to mount the. IMG file with magic disc but can not mount it. I guess not enough to replace the init file in the destination folder? I tried but during boot change the resolution, and the screen remains fixed on a keyboard in the middle where you can not interact. As was the case before ... Could you explain in detail how to replace the init file, or at least to run on the touch rhobuntu elf?If you want to write me a pm. Thanks

did you replaced the init file?

Thanks buddy, I managed to get it installed. Mistake was mine, I copied Ubuntu.img file in ubuntu directory. as i moved it out on storage card root, it got installed.
But after installation there was a big key board on screen which i managed to drage down with stylus. but what I feel is the resolution need to be changes as it is showing everything so big.
Also, I tried to make a call to this device, we get ring at device from which I was calling, but there was nothing on the device on which I install rhobuntu. also I could not make a call from here. Can you help me in these cases.
Found something while starting rhobuntu, you may be interested to know.
While starting rhobuntu from haret.exe at one point it shows starting ophono daemon something, where it says can't create signal descriptor file. is it helpful to resolve this issue?
Gourav

Hi,
Got installed the Rhobuntu can access it. Facing two issues on it as follows;
1. Phone function not working as ofono daemon says - can not create signal filedescriptor: Function not implemented
2. Resolution are not as per device.
Please anybody help me to get all this working.

[Q] Rar on android.

Hi:
I've recently started to develop my own comic reader. The problem I've come up with is cbr files, which are esentially rar files. Now I know there are comic readers out there (all of them, I think) that support cbr files. So there is a way of doing this, I just can't find how.
In the rarlabs official page (search google rar addons and it's the first page) there are several options. I would like to know if I download the commandline arm unrar how I could install it on Android (I have a motorola Xoom, it would be for Honeycomb), assuming that is correct.
If this is not an option is there a command line unrar application that I could call from my own? and How would the code be (to call an external application, that is)?
If the above is not possible, what is the way to get to unrar something in android?
The only real option I've seen would be to use junrar (hosted on github)
But it seems complicated and I'm not sure it works very well as I've seen a lot of conflicting reports.
Thanks for any help!

Try http://www.all-freeware.com/results/rar/for/android to unpack rar on Android.
Success,

Hi:
I'm not exactly sure what you wanted me to try. There is nothing in that page that would allow me to uncompress a rar file on android. Only a bunch of unrar utitilities and some android things but they are not related, that is, there is nothing that says unrar that also works on android.
thanks anyway.

Unrar
great app available here: androidzoom (dot) com/android_applications/tools/unrar_dhpu.html

Hi:
It's seems that I didn't make myself clear.
I want to develop an android application that needs to unrar files. Is there a way to call the unrar application from my own code?
If so, can you tell me how?
Otherwise, I appreciate the effort, but I can't use that.
Thank you very much!

You can bring the unrar binary along in the /asset of your app,
on first launch copy it to your apps /file directory, chmod +x it, and use exec("sh") to unrar the files from shell.

oh, I see. I think I get the the idea but I don't understand all the instructions.
What did you mean by importing thebinary on my asset?
If I do the step above why do I need to copy the binary on first launch?
Don't I need root privileges too chmod it? And how do I do it from my source code?
And finally where can I find the command line use of the application? Or is it the same as the Linux version?
I know there are a lot of questions, but please keep in mind that I'm very new at doing this.
Thanks for all the help!

You need to put it as asset to bring it along.
You need to copy it because asset files are not directly accessable.
You don't need root to chmod the file in your own directory.
You do it by using a shell from your code i.e. Process.exec("sh")
And finally you want to program the app not me,
so don't be lazy and invest some time.
Google google google google...
If there are still questions left after that, you may ask again .

Ok, I'll try it and get back to you!
Thanks!

Sorry for my lazyness, but I've been Googling for a good half hour without finding a simple 'unrar' binary executable compiled to run from terminal on rooted ARMx32 device. I don't want bloated GUI APK's or libraries for development implementation, but just the plain command line interface executable. Anyone, please? It's a pity they haven't baked it into Busybox as an applet, IMO.
