/system writable with unionfs

Hi,
I've followed the instructions on how to build froyo on Ubuntu 10.04 32Bit,
I had to disable gdb in /buildroot/local/g8_arm/g8_arm.config
or shot make -i world
make menuconfig breaks everything
....so edit configs by hand.....
then it builds fine.....
thanks to his patch:
www android-hilfe de /android-os-entwicklung-customize/4801-kernel-module-kompilieren-erster-versuch.html
it runs (else unionfs complains about missing symbols..)
Code:
adb push unionfs.ko /data/local/tmp
adb push ntfs.ko /data/local/tmp
I've created a second 2GB ext3 partition on my sdhc class6
Code:
insmod /data/local/tmp/unionfs.ko
mount /dev/block/vold/179:18 /data/newroot
mount -t unionfs -o dirs="/data/newroot/rootfs=rw:/system=ro" unionfs /system
and now i've things like a writeble host file .....
it runs since yesterday here - and is fine.

For morons like me what does that mean....root access??
Sorry if that is a dumb question

@mothy
so far, temporary root with writable /system directory

So just to be clear. Do you replace the kernel at all?
And do you have to mount the sd partition every time you boot up?

It's for the original Archos Kernel 2.6.29-omap1
Code:
# lsmod
ntfs 213028 0 - Live 0xbf276000
unionfs 74364 1 - Live 0xbf211000
this means you have to
temproot+"re"mount
the writable places, maybe soft-reboot (i use LCDDensity, it's soft-rebooting) and all your're changes are magicly there
instead of using sd, you can just create /data/newroot and let the things go there
Code:
# df -h
/dev/block/mmcblk0p4 299.4M 205.1M 78.9M 72% /data
i don't see any new rom's soon, unless we get a new bootloader, Archos uses mmcblk0 (an SD-Card device) and not mtd, so i think we can forget all that fastboot, flash_unlock mtd stuff.
this is very annoying, maybe i'm wrong,
but it looks like they don't want us to reflash the device :-(
unionfs usually need a own kernel, but the "ugly patches" make it run with the archos gen8 kernel
So i use temproot, gscript, LCDDensity after each reboot - and have all my settings back, apps like adsfree runs...
jens

forgive my lack of knowledge but you keep mentioning ntfs in the code fragments but you havent actually said that this is giving you ntfs support. does your kernal changes allow for reading ntfs volumes?

yes, i hope so, but i havn't tested it until now, minimum is that you can mount ntfs volumes by hand - but maybe it's automounting....
i want test a HD movie from sd, but mine doesnt fit in 4Gig (fat)

USB Host mode on Defy

Has anyone tried Defy's USB Host mode?
Would like to attach USB devices onto Defy:
- USB keyboard / mouse
- USB disk drives
- Other types of USB 3G modems (like CDMA1x/EVDO)
- Arduino IO board
...
I haven't bought Defy yet, but want to do some pre-research before the purchase.
Could someone do me a favor to post the outputs of "dmesg" on Defy?
(Run dmesg command under the Linux console).
I expect to see something like:
Code:
...
OMAP3630 ES1.1
...
twl4030_usb twl4030_usb: Initialized TWL4030 USB module
usbcore: registered new interface driver usbfs
usbcore: registered new interface driver hub

musb_hdrc: version 6.0, musb-dma, otg (peripheral+host), debug=0
musb_hdrc: USB OTG mode controller at fa0ab000 using DMA, IRQ 92
...
I got above dmesg by Web searching for an OMAP3630 test board, not a Defy.
Just want to make sure Defy is equipped with USB OTG controller.

This function not supported in the kernel, so kernel we can not replace, because bootloader is locked.

Understood the bootloader is locked by Moto, and a kernel must be signed.
Instead of replacing kernel itself, can we just load new driver modules (*.ko via insmod command)?
Does Moto also prevent from loading customized driver modules?

Can someone help to get the outputs of "cat /proc/driver/musb_hdrc" ?
Something like:
Code:
#cat /proc/driver/musb_hdrc
Status: MHDRC, Mode=Peripheral (Power=60, DevCtl=80)
OTG state: b_idle; inactive
Options: musb-dma, otg (peripheral+host), debug=3 [eps=16]

Root port status: 00000000

One correction to my previous command line for current USB mode:
"cat /sys/devices/platform/musb_hdrc/mode"
Following dmesg of Defy shows the internal USB modem is attached to the USB Host for modem init. But later reset as b_peripheral:

How about to use:
"echo b_host > /sys/devices/platform/musb_hdrc/mode"
to enable the Host mode again?
May run command "modinfo musb_hdrc" to get actual parameters we can use to enable the Host mode.
Something like "modprobe musb_hdrc mode_default=1".

$ cat /sys/devices/platform/musb_hdrc/mode

It would be very great if this will work.
Is there any progress?

yeah, be nice to connect 2 usb hosts so i can copy my slr pictures from a 32gb sd card over to a 320gb hdd.
I have usb y cables so i can power the hosts with an external usb charger.

Any news on this?

It will be nice to see an USB host patch/mod on Defy

hi
I've seen that some phones will enable host mode if you boot them with the data pins shorted, done with a "dongle". anyone tried this on the defy? I'll make one and try it if no one has.

hmm.. is that safe? I dont want to burn my usb port..

I doubt it will damage anything. they won't be able to source enough current.
I've checked and the omap3610 supports usb otg. I will try to test this weekend.

Scratch that, it is not the data pins, you connect the "extra" pin (pin 4) to ground.

Maybe this could help, would love to be able to play video files from a external HDD. Watching movies on the backseat while we drive to our vacation!

maybe we need another kernel,i think

[Q] how can I debug otg connections

SOLVED: defective otg cable
useful tools:
any android terminal emulator plus root
dmesg
lsusb
2nd otg cable
I cannot seem to get otg working with any of the various USB storage devices I have.
Any ideas on how I can debug this?
If it were normal Linux it would be easy enough, however it's not.
Any suggestions would be appreciated.
Running AOKP buttered right now but sentinel stock and paranoid all do not work either. So it might be a cable or the tablet even.
Hmm not sure but I wonder if the kernel with this rom is missing the fat kernel modules
Thanks

I had the same problems with rooted Stock and various custom ROMs. Try installing "USB OTG Helper [root]" then retest. This app helped get me RW access to OTG storage from SD cards to powered HDD drives in various formats (ext2,3,4 and NTFS).
It worked so well I paid for the donate version just to support the developer. It even has exFAT support although I never tried it. Personally I think it should be part of standard Android.

Have you checked "lsusb" or "udevadm" in terminal if the device recognizes anything?

Thanks more commands to jog my memory and try
I installed a console app and can check dmesg and other stuff.
Lsmod and related seem to be mostly obsolete.
Dmesg shows something is seen but the system keeps failing after this.
I see the same messages regardless of which device I try, powered and unpowered.

ok problem solved.
The final debugging step was to "get another otg cable and test to make sure the first otg cable isn't defective"
Since I only owned a single OTG cable at the start, it was sort of difficult to perform this ultimate debug step.
But once I tried a different cable, almost everything worked just fine.
Only my 64gb micro-sd cards gave me a little trouble, but they all work now.

U8800 not detected by pc

Hello,
I have an issue with my U8800.
It is not detected by my PC (Windows 7 x64). When I say it is not detected, I mean nothing happens. Tried all USB ports. In fact, I have tried the phone on 6 diferent PCs (4 with windows 7 x64, 1 with windows 7 x86 and one with Vista x86). The best I could get was usb not recognized (but very quickly) in one of them (x64) but not replicated. It doesn't matter if you go to Pink Screen, with battery, without battery, with sd card or without, etc. Have tried forcing all kinds of drivers, without success. Android SDK is fully installed, etc.
I also tried using 2 diferent Linux live OS's. On one of them, I was able to mount the "CD - the one with the drivers", but again, only once.
I was using Aurora with latest update when this issue started. Never partitioned. I have downgraded to Rom 136. Tried B517 and B528. I'm only able to root the device using Z4root with froyo.
Tried 3 different cables and all of them work without any issues with a Galaxy S3 and a ZTE Racer.
The funny thing is that the U8800 is detected by my car audio system (it uses windows CE 5.0) and plays media files fine. Even the USB Debugging shows up. On another car, with a "usb radio" it also works.
The device itself charges fine in every usb port i have tried
Any help would be appreciated.
Thank you

Hi guys, just an update.
I forgot to mention that the device itself does nothing while connected to the pc. No USB mount or USB Debugging icons. Just the charging message and the lightning icon.
I have tried the device on 5 more PCs and 3 more cables. Not much luck. I did get a few odd behaviours.
This is what I have found out:
Windows 7
With the phone OFF:
If I just plug in the usb cable, it will turn on and after a few seconds, the battery image will appear. While doing that, by using UsbDview, I can see USB Mass Storage Device with the idVendor=12d1, idProduct=1037.
Windows displays "Unrecognized usb device" and a pop up says that windows was unable to find/install drivers for the "unkown device" (error 45 - device is not connected).
Phone turned ON:
If I turn the phone on, no error is displayed and no attempts to install drivers are made. Nothing happens.
Ubuntu (12.0x) - Using the same method with the phone turned OFF:
Dmesg displays:
usb 5-1: new full-speed USB device number 5 using uhci_hcd
hub 5-0:1.0: unable to enumerate USB device on port 5
If I insist, by removing the usb cable, a few times, I get this:

Phone turned ON:
Only when this information is displayed, If I turn the phone on, it will connect to linux. Usb debugging will come up and I'm able to mount the SD card.
This is very weird. Can anyone help me with this issue?

Hello again,
Over 100 views and not a single idea???
One thing, when I connect the phone to Ubuntu (not in pink screen, as it doesn't work), the internal memory is seen as unallocated. Is this normal? It say 2.0GIG but no file system. I have access to the internal memory on the phone itself. Could this be a clue (The external SD card is visible and accessable).
When i type adb devices, no device is present or if I use adb shell, error: device not found.
lsusb and dmesg show the device.

A have, at this moment, B517 installed (tried 136, 138, 518, 526, 528 with the same results).
Come on guys, I don't believe this to be a hardware issue. Please help!!!!!!!!!
P.S. I still have IMEI, serial, etc.

It is a strange behaviour. The only thing I could recommend you is dial *#*#2846579#*#* and see the usb port setting. On stock ROMs you should be able to change it to something like "normal" or "google".

Belfish, thank you for the reply. I have already tried that. Same result. Someone has suggested if the vold.fstab file has been moddified. I have never touched it so I don't know what I'm looking for. This is what's inside the file:

Is it supposed to be like that?
Thanks.

The vold.fstab shouldn't matter much. If it is wrong, then it would not let you mount sd card in android too.
I don't really know how to help you. I know there are some NV items that could alter the USB interface, but it's mostly in the kernel side. Maybe you can check your "dmesg" log on your phone. Using a Terminal Emulator, first write su for superuser and then dmesg. It gives you the kernel log messages in Android side (the phone).

Ok, I will do that. I just need to go back to 2.2 so I can root it. Once I have the Logs, I will post it. I really hope to solve this so I can try your new rom. Thank you Blefish
P.S. Is there anything I should be looking for?

Phone bricked - is this a hardware problem?

Hi,
my phone stopped working this morning pretty much out of the blue: It was working fine one moment but then switched off, even though the battery was practically full, and could not be turned on again.
I think it was stuck in a boot loop: It hung at the LG logo, the LED was alternating between blue and green, but nothing else happened. I also wasn't able to reach the recovery mode.
After some research I made it to download mode and tried to flash a stock ROM with LG Flash Tool - this had the effect that I now can't even go to download mode anymore.
When I plug the phone into my Linux laptop and run `dmesg` I get this output:

So, it does show up as QHSUSB__BULK but there also seem to be some I/O errors - is that fixable or did the phone just break after 3.5 years of constant usage?

hi there, unfortunately this is a known issue that sometimes happen with LG devices.. it happens to me too and I solved it (but I have other issues, too ): this tool could help you: https://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076 - only Windows btw.. but PLEASE before trying anything ask for details into the thread because you the tool we'll do invasive stuff on your device! there is no other way to fix so it's a bottleneck, I fear.. the tool itself works and it's safe as long as you know what you are doing, this is what I'm trying to say
