OK ROM comes - Page 15

joshewah · 06/10/2009, 04:33 AM

Its rootfs though, I think its mounted from a ramdisk image. So the image from the first post in this thread that wasin the jar with all the files... that is in ROM and mounted into memory on boot.

I guess I should try and write a test file and then reboot and see what happens.

joshewah · 06/10/2009, 04:37 AM

Phone was rebooted:
root@castle:/boot# uptime
03:36:18 up 2 min, 0 users, load average: 2.26, 1.26, 0.49

And the file I put in /boot was still there. So no problem changing whats in /boot if you wanted to.

One cool thing, you can connect to the phone again before the GUI is even done loading. I was in while it still said PALM.

Yes! I have made my first successful application modification! I have modified the camera to no longer make the shutter noise even with all system sounds enabled, and everything on.

Required re-mounting the root partition rw - and then making my modifications - and finally rebooting the phone to pick up the changes. But it worked!!! Yay!

Really excited to see what you guys can do with all of this

btw. did you see that

I would increase the vibrate on email/SMS for more than 1 sec. Up to like three sec.

BlackFlag77 · 06/10/2009, 05:01 AM

Yeah, the vibrate is terrible... I'd say it's more like 1/3 of a second. I can only feel it if I'm sitting down absolutely still.

scm6079 · 06/10/2009, 05:02 AM

Whoo hoo!!!

My first application works!! I'm so excited! It's just a pretty "hello world" application with a few simple command tests - but hey - it's a working application on the pre!

Here are the steps I took:
* Enable dev mode, log in as root
* Remount the / partition for read write with the command:
mount -n -o remount,rw /
* Started by picking an application I didn't care much about - i choose the nascar app.
* Found that application's directory: /usr/palm/applications/com.handson.app.nascar/
* remove the imports for stuff I didn't need/want
* created a new home view that displays my app
* Added controller / additional code as needed (for me just a couple functions, mostly copied from other apps)
* Saved all the changes. I edited the files on the device with vi.
* Rebooted my phone
* started the application by clicking on the existing application icon.
* Sat back and smiled as my simple application worked.

The api in the js really seems pretty nice. Palm did a good job. Honestly, this is much cleaner than when I was going through the earlier palm os stuff for my i500 / i330 apps.

scm6079, that's awesome to hear. It looks like we have a temporary workaround while waiting for the SDK to be delivered. Granted, dev workflow will be a little rough without the tools they likely provide, but this is absolutely the beginning of independent, non-SDK-dependent Pre development in the meantime.

Earlier tonight, I was contemplating doing the exact same thing: Use a predeveloped app, study it for a bit, and refactor it (using information gleaned from said app and others) to do my bidding. It looks like I can finally begin work on a couple I already had in mind with this information revealed.

Enjoying sitting back watching people speek in a language I don't understand...

iphony · 06/10/2009, 05:13 AM

palm will obfuscate all javascript soon...

Ask and you shall receive! My phone now vibrates 3 times...

Here's the change,
Line 129, /usr/palm/applications/com.palm.app.messaging/app/controllers/notification-assistant.js --

find the line:
this.controller.playSoundNotification('alerts','');

This plays the alert. Now just add 2 setTimeout commands (takes the function to call, then the time in ms.)

So you have:

setTimeout( function(){ this.controller.playSoundNotification('alerts', ''); }, 1000 );
setTimeout( function(){ this.controller.playSoundNotification('alerts', ''); }, 2000 );

Adjust the 1000 and 2000 parameters to your liking. Follow my guide on modifying to put this in place, and you now have a long tone.

This phone really is going to fun - it is *sooo* easy to modify.

Excellent work, scm. My main concern would be persistence after the next revision, but these tweaks seem easy enough to do assuming access remains available moving forward.

JS obfuscation would present a sort of performance hit, IIRC.

iphony · 06/10/2009, 05:17 AM

no, obfuscation actually increases performance by using shorter symbol names

vanadium · 06/10/2009, 05:18 AM

You actually have a point there based on my dealing with XSS attacks in the past. It's been a while.

Regardless, even if JS is obfuscated, wouldn't it (for the most part) be beside the point with the framework already out in the open and the SDK perhaps only a couple of months away? Part of me thinks that, with this knowledge out there and being actively investigated (to the delight of the developer community), Palm isn't going to run around closing the gates at this point.

Hey guys, found the svn but I doubt we can access it.

Code:

Source: svn://subversion.palm.com/main/nova/palm/luna/framework/submissions;module=175.7;proto=http svn://subversion.palm.com/main/nova/palm/luna/framework;module=trunk;proto=http file://buildin-framework file://JavaScript/Minifier.pm

Cheers

The SVN address isn't in DNS, so it's not going to be easily accessible, if at all.

The Luna/Mojo framework sources are in the root image (it's JavaScript after all!)

-wireless- · 06/10/2009, 05:25 AM

Yeah but it would be nice to see all the updates :P

Yeah... it'd be nice if we had the actual source code, but it'll be a cold day in hell...

scm6079 · 06/10/2009, 05:34 AM

So I've been digging through the camera in detail to add a few functions I want - including letting me set an auto-timer - and there is some *hilarious* code in there.

//NOTE: The Captured event _could_ come in earlier if the SetSnapshotDelayDuration function ever get
//added and called and was used to reduce the capture freezeframe to less then 1second ... OMFG!

So I have the camera modified to add a "5 second timer" button - that let's me click it and then turn the phone around to face me before it takes the picture.

I'm also looking to modify it to be able to use the flash as a flashlight (like my old moto q) - but haven't found enough for that yet.

There are 998 "TODO: " references in the source base. If you want some really funny reading, you should run this command as root on your phone:

find . -name "*.js" | xargs egrep "TODO"

Read the comments - they are great.
