It's me again :p

Seems that i'm nearly the only one who suffers from this specific trackball issue.

Anyway i won't give up so early and i really hope to find the reason of this	erroneous inputs.

After checking some of the system libs and the framework files concerning file integrity, i started some rudimental debugging with adb.

Working with the tool getevent i found out that input event2 (trackball) is detected correctly and disappears if the trackball remains untouched.

When the random inputs are going to start, input event3 (virtual keyboard) occurs though i did not touch anything (especially not the virtual keyboard) :confused:

If i am at home screen the inputs hit google search entry field and most of the time the number "3" is printed.

Input event3 stays active until i fiddle around with the trackball or press some hardware buttons. This sometimes stops the weirdness :o

I also did check the interrupt counting with cat /proc/interrupts.

Everything looks quite normal....

I am really wondering what is causing this.

Maybe it is a side effect from some damaged hardware part (maybe MSM7201 itself) or it is some software bug that has never been observed before.

Maybe it is the result of some bad timings...

Really got no clue right now!

EDIT: Just for completeness. Also did perform RAM test and other hardware diagnostic with DREADIAG. No errors here!

i have trouble using recovery too. I have to press it very lightly to get it to select only once otherwise it clicks several times ><

Not a huge issue for me really, i don't use it that often, but it is pretty irritating.

But, no. I've never had it enter any numbers or anything, that is strange.

However, i do have a strange problem where when the phone receives a slight knock, like if it's in my pocket and it bangs against something, or i drop it a couple of inches onto my desk or something, a random app will launch. I have no idea why this happens and it's not anything coming in contact with the screen because it happens even when it's locked. It's usually the market which opens too for some strange reason. Oh, it also reboots sometimes too :p

Yeah, i think i need a new phone :D
[G1 General] lbcoder:
Virtual keyboard? Or touchscreen? Is the virtual keyboard actually listed as a separate input from the touchscreen? If it is, then how could it even be triggered when the vk isn't even opened? Or is the vk open when this weirdness happens? Could it simply be the digitizer that's borked?

Here's a REAL SIMPLE IDEA: clean the digitizer with rubbing alcohol. Can't hurt, and now that you bring touch events into the picture, there is a little bit of a dejavu feeling starting to come over me -- not from personal experience mind you, but I do recall someone mentioning something about a greasy digitizer causing some weird problems.... that went away when it was properly cleaned.

And if nothing else, if it happens to be a digitizer problem and the digitizer is totally borked, try disconnecting it. You should still be able to navigate by trackball and hack on it without a functioning touchscreen.
[G1 General] scholbert:
I know it sounds confusing, but it's true...

Thanks for the replies!

Yepp!

Yepp!

BTW, you may type characters on the vk simultanously, while there are numerous 3's fired from somewhere inside the system.

The ascii changes if i also scroll the trackpad....

If you are able to close vk it opens up again randomly

Nope!

Already did test with disconnecting the digitizer, same behaviour.

Very wicked and confusing :eek:

I really think there must be something destroyed inside the MCU.

Short circuit or ESD damage on a GPIO bank of the chip.

I will do further debugging.....

[G1 General] scholbert:
...not givin' up

Hey there,

i don't know if this is still of interest for someone, but anyway here's updated information about this confusing behaviour:

- booting into recovery console (different kernel, only initrd running from RAM)

- scrolling up with the trackball causes ASCII char "u" in this console

- after scrolling the hardware keyboard is blocked

Using SHR kernel:

- used sd boot image from leviathan and flashed it to the boot partition

- sdcard is used as rootfs

- system boots up after login i enter the console

- scrolling up with the trackball causes strange ASCII string "u542i3" in this console

- after scrolling the hardware keyboard is not blocked

Pretty sure that some parts of hardware are causing this "ghost" input.

I decided to put the mainboard into pure alcohol for some hours.

Though the humidity stickers on my mainboard never turned to red, i just want to make sure that there's no dirt causing this strange effect.

Anyway it's my last hope....:o

P.S.: Anyone ever programmed a simple commandline tool to observe the state of the systems GPIO?

Would be very helpful to find the needle in the stack :D

EDIT: In the meantime i found out a lot, about the internal components of the HTC dream.

If there's some interest, i may open up a new thread post some information about it.

Cheers,

scholbert
[G1 General] scholbert:
O.K. no ideas anymore.

Quoting myself:

Last hope has gone!

Some hardware part has also gone, i suppose.

Battery life was always very worse using this mainboard, which is another indicator, that something hardware related had gone mad.

Anyone??

Whatever, i think i'll use that mainboard for some awesome experiments :p

Bye bye,

[G1 General] ram5ay:
Hey, new to this forum, and just stumbled across your post searching for a resolve to my problem, which seems to be very similar to yours.

Phone seems to work fine except:

When rolling trackball up (even slightest movement) I get virtual keyboard appearing on screen and u542i3.....(continuous 3's) types into the searchbar.

Also MENU button is inop, although one on keyboard is ok.

When locked, sometimes the screen and key backlights constantly go on and off.

Seems to flatten the battery pretty quick.

I stripped the phone checked everything clean and dry etc, tried turning the trackball upside down on the offchance, but no change. I have done nothing software related as I'm not too clued up on that side of things. It has the std 1.6 operating system as far as I know.

I have no clue where to go from here with it though, think my best bet might just be to get another one that needs a screen or something and use mine for parts?

Good to see I'm not alone with this issue though so there's a chance someone may figure it out.
[G1 General] scholbert:
....at least i'm not alone

Hi ram5ay,

thanks a lot for your reply!

That's exactly the behaviour of my device.

True, i also observed this issue.

Seems that parts of the hardware are damaged or not set up correctly due to some other error.

As a result some of the GPIO's may act as an output and are shortened to Vio or GND. This could be a reason why the battery got drained so fast :(

Anyway, as i already wrote down, got no clue how to fix this.....

Best regards,

scholbert
[G1 General] ram5ay:
Cool man, no worries. Maybe futile, but I'll prob pull mine apart again and have another look, if I have any success I'll keep you posted.
[G1 General] Da Bealez:
ive had nothing but trouble with my dream recently!

the backlight doesnt work when the phone is closed but works fine open?

my trackball doesnt scroll up, my phone scrolls down when i have it charging or plugged into a usb cable but never does it otherwise?
[G1 General] scholbert:
Strange trackball issue fixed!!!

Hey ram5ay.... and of course thoose who realized similar problem with the trackball but did not join the post :rolleyes:

Good news!

Found the reason for this strange behaviour and fixed it :D

Because my other device got damaged i started to investigate on this issue again. Guessing that there could be a short circuit between two GPIO lines i had a closer look into the linux kernel drivers for keypad and trackball.

Doing this i stumbled over the fact, that the characters printed out (u542i3...) belong to the same row of the keypad.

In this case GPIO42.

Second i had to find the GPIO line of the sensor that indicates trackball moving UP. I started to trace some signals on the mainboard and on the sub-PCB (trackball).

After a while i was able to find the meeting point of both signals :p

It was located at one of the EMC-arrays.

Unsoldered the broken component and.. resoldered spare part... solved :cool:

I think i will prepare some pix for the weird ones.

Cheers,

i've been having this exact issue for quite some time now, and i'm really glad u found a solution :D but can u please explain yourself a bit further? :confused::confused:
[G1 General] tevroc:
I'm having what seems like a similar problem with my tmobile G1.

Pressing del types JHGL and fiddles with ringer volume, enter types amncs,x, spacebar types / ~Z{ , p types pq8yt19d, back types U542i3.

When in Amon_ra recovery console however, all keys and buttons function normally.

I can hand solder very small things and would be willing to try this. Please elaborate a little bit if you can. Thank you!
[G1 General] scholbert:
Hi!

Keyboard taps and the trackball scrolling are detected by GPIO lines of the CPU on the Dream mainboard.

To prevent these signals from ESD the are protected by special circuits.

See the pic in my last post...

Due to some unknown effect in the past, one of these cicuits got damaged itself and caused a short circuit between two of thoose lines.

This led to the erroneous inputs in my case.

To get this more clearly look a this mapping of the keypad (just one of the mappings to give an example):

back -emenu- U - 5 - 4 - 2 - I - 3	row_0 (in) gp_42 irq_106
| | | | | | | |
home -send - 7 - 6 - R - W - 0 - E row_1 (in) gp_41 irq_105
| | | | | | | |
x - x - K - B - V -lalt - O -comp row_2 (in) gp_40 irq_104
| | | | | | | |
bksp -lshft- J - H - G -v_up - L -v_dwn row_3 (in) gp_39 irq_103
| | | | | | | |
enter- A - M - N - C - S -comma- X row_4 (in) gp_38 irq_102
| | | | | | | |
rshft-menu -dot -space- @ - Z -ralt - F row_5 (in) gp_37 irq_101
| | | | | | | |
P - Q - 8 - Y - T - 1 - 9 - D row_6 (in) gp_36 irq_100

col_0 col_1 col_2 col_3 col_4 col_5 col_6 col_7
(out) (out) (out) (out) (out) (out) (out) (out)
gp_35 gp_34 gp_33 gp_32 gp_31 gp_23 gp_30 gp_109

This mapping was taken from the kernel sources, i just re-arranged to make it human readable...

If some of thoose lines are stuck together or stick to GND or VCC you'll get very wicked behaviour, because the event sub-system of Android will get wrong inputs.

As you see there are also dedicated IRQ-lines for the rows. If they get stuck at a fixed level you'll get permanent event triggers.

So did mine as long as i left the trackball untouched.

On my device a signal detecting the trackball move was affected.

Maybe it's a different line on your device..

Please have a look at the mapping above and re-read what i've written in one of my first posts:

Hope this helps ;)

Good luck!

[G1 General] tevroc:
Thanks for the info! What seemed to be a permanent problem (happened for 2 days after I riced it) is now intermittent. I'm not so gung ho over opening the phone now. I think ill just live with it until I get a new phone. After that ill fix it and then put it to use for something that doesn't need a sim card.
[G1 General] renesix:
Same "U542i3" problem when I press the trackball. Where can I find the spare parts to buy them?
[G1 General] scholbert:
Hi renesix!

The part could be easily located in the pic posted here:

http://xdaforums.com/showpost.php?p=5934138&postcount=24

To repair my device i took another damaged mainboard, unsoldered the part and replaced it on the non-responsive board.

You may do a search in the web for a replacement part:

For example EMI filter arrays from Panasonic or TDK.

If you don't care about EMI protection, a resistor network with 4 lines should also do the job.

Take care about the component size.

[Nexus One Accessories] dills84:
i have one... its really nice. Very snug fit and has all the cut outs for 2nd mic, speaker, flash, ect...

well made and highly recommended. especially at such a cheap price.

attached a couple of pics with the case on my nexus... hope this helps.
[Nexus One Accessories] bug666:
Its similar to the cases for the mytouch/ magic but not as sturdy, probably because the phone is thinner and is really really snug. Unlike the silicone cases you cant pull this off just taking it out of your pocket.

The case thickness is slightly higher than the camera on the back which protects it somewhat from scratching the plastic lens cover.

On the front the ridge is high enough to prevent accidental screen touching tap the edges of the screen.

The buttons are still easily operable and does not interfere with the charger, mics, or speaker at all. It does cover two of the three gold connectors so it might be a problem when the docks come out.
[Nexus One Accessories] metallicant:
I just ordered the very same case on ebay, along with the clearfreak screen protector.

To those who have one:

How easy/difficult would it be to remove the ugly (in my opinion) pattern from the skin?
[Nexus One Accessories] parrot5:

[Nexus One Accessories] spr33:
I bought one because I'd rather not have my phone all scratched up. I will be attempting to remove the pattern when it arrives, probably with some nail polish remover first and then onto some acid.

anyone try/have this silicone case and care to comment?

This is what my wife is wanting... just want to make sure its snug, looks of quality, and has all the necessary holes cut out.
[Nexus One Accessories] slimm13:
Agreed +1.
[Nexus One Accessories] student.driver:
Yeah. I love the material, clarity, and fit (I have the green one) but I don't care for the pattern. However, I realized that I don't actually see the pattern all that often so it doesn't bother me. I'm thinking of getting another; I got mine from Amazon (it was on there at least the day before the phone was announced) and I might get the blue one next.
[Nexus One Accessories] parrot5:
I found a smoke-colored one on Ebay. I guess I'll pick up the smoke one, as the back of the phone is dark-gray, the checker pattern doesn't stick out as much as the white (or green or blue or red or purple) one.
[Nexus One Accessories] metallicant:
I just got mine today. I love how snug the skin fits on the N1 and also the pattern isn't so ugly in person. IMO this is currently the best body protection for the phone and it's worth every penny spent on it.

Hi to all,

I try to explain this (my english language is poor)

When i open with gallery an high quality image i see it in lower quality then really it is and if i set it as home wallpaper it is still in low quality.

Before i thought that Hero's screen had not enough colors (i think 262.000) to display all shadings, but after i tried to set as home wallpaper the same image with another app (Wallpaper Set & Save or Wallpaper Plus) and the image/wallpaper was perfect.

For to be more clear i added 2 screenshots of same image set as wallpaper with default Album app and with "Wallpaper Set & Save".

In first 3 black blocks you can see big differences of quality. This is only an example but i have same problem with other images and not only when i set them as wallpapers, also when i watch them with album app. Am i the only one with this problem or album app is buggy?
