PRS-T1 getting adb working

Thanks uboot.

This is not very difficult...

I did it adding this just before the mount command:

if ! ( grep -c "/mnt/sdcard" /proc/mounts ); then
   sleep 10
   if ! ( grep -c "/mnt/sdcard" /proc/mounts ); then
      sleep 10
      if ! ( grep -c "/mnt/sdcard" /proc/mounts ); then
         sleep 10
      fi
   fi
fi

Thanks j0534ng31， it worked!

But as I tested in terminal, the script will always sleep 30 seconds.
That is, ( grep -c "/mnt/sdcard" /proc/mounts ) is always return FALSE.

Or a trigger can be implmented? Once the /mnt/sdcard was mounted, the command will be excuted.

And, before /mnt/sdcard/ was mounted, the system had already loaded some fonts from /ebook/fonts, such as DroidSans.ttf. I want the system load all fonts from /sdcard/fonts, so it's better to mount /mnt/sdcard/ at first directly, then bind /sdcard/fonts to /ebook/fonts as soon as possible. Not to wait the system to mount the sdcard.

I suppose that it returns always FALSE if you don´t have busybox correctly installed, as you don't have a 'grep' command... try 'busybox grep' instead...

It's very possible you are right

Again, I suppose this can only be solved by using one of the other approachs: to edit the boot image (very dangerous) or to edit the fonts cramfs image (very easy) and replace the system fonts.

Thanks for your reply!

Because my font is very big, 12MB, so I can't made a cramfs image which is smaller than the original image.

Later, I put one font in /data, can be binded successfuly before the system loading fonts, because /data has already been mounted when the install-recovery.sh is running.
The weakness of putting fonts in /data is occupied much space of /data.

I just don't know how to mount /mnt/sdcard mannualy in recovery.sh.
mount -t vfat /dev/block//vold/179:1 /mnt/sdcard?
I can successfuly excute this command in terminal emulator, mounted to a temp directory /tt,
but after I put it in install-recovery.sh, after reboot, mount was failed.

What about mount /dev/block/mmcblk2p4 /mnt/sdcard ?

If you want do it the same way as the system (by using vold), you have to:

To know the volumes mounted:

vdc volume list

To umount the internal memory (SD card):

vdc volume unmount sdcard

To umount the external Micro-SD card:

vdc volume unmount extsd

To mount the internal memory (SD card):

vdc volume mount sdcard

To mount the external Micro-SD card:

vdc volume mount extsd

[xuyn2003]

Thank you j0534ng31, for the command string.
I can vdc volume mount sdcard in terminal, howerver failed in install-recovery.sh.

Oh, hey! That's it, got success!

The remainning problem is that the file names are some different from the orignial sdcard, so some APKs can't read their datas from sdcard.
I think that is because I missed some parameters in the mount command.

I recorded the out put of "cat /proc/mounts" of orginal mounting as below, how can we add those parameters to the mount command? which should be after "-o", which should be after "-t"?

/dev/block//vold/179:68 /mnt/sdcard vfat rw,dirsync,nosuid,nodev,noexec,noatime,uid=1000,gi d=1015,fmask=0002,dmask=0002,allow_utime=0020,code page=cp437,iocharset=iso8859-1,shortname=mixed,batch_sync,uft8,errors=remount-ro 00

Instead of the above instructions, use:

vdc volume mount /mnt/sdcard

[xuyn2003]

Finally worked it out, thanks for uboot and j0534ng31's help.
Now I can replace any fonts of /ebook, including the system UI fonts.

#!/system/bin/sh

mkdir /data/altsd

mount -o noatime,utf8 -t vfat /dev/block/mmcblk2p4 /data/altsd

afd=/data/altsd/altfonts/
fts=`ls $afd`
for ft in $fts
 do
  mount -o bind $afd$ft /ebook/fonts/$ft
done

Why not mount to /mnt/sdcard directly? Because if mounted to /mnt/sdcard, sometime later, when the system do the mount procedure, will got faliure because /mnt/sdcard was already occupied, and some related action will not be done. To avoid this, I mount to another directory.

As to VDC, I guess that it has not been initialized when the install-recovey.sh is running.

One query - do you need to deal with the possibility of font files with spaces in the names? You might need to do something like:

afd=/data/altsd/altfonts/
fts=$(cd $afd; echo "*")
for ft in $fts; do
  mount -o bind $afd"$ft" /ebook/fonts/"$ft"
done

or

afd=/data/altsd/altfonts/
ls -1 $afd | while read ft; do
  mount -o bind $afd"$ft" /ebook/fonts/"$ft"
done

where the " marks are important.

Cheers,
Simon.

Hi Simon, thank you for the reminder.
But only those fonts whose filenames are equals to the filenames in /ebook/fonts will be binded, and I didn't found any filename in /ebook/fonts contains space characters.

Hi,

Even though I have installed the enable-adb package (or think I've been able to do that), and I have edited the ~/.android/adb_usb.ini file with these contents:

0x054C

I cannot connect with ADB under Linux. :-(
I have also activated the Debugging USB.

When I connect the cable, I see the Android icon in the upper left corner of the reader.

lsusb correctly detects the Sony Reader:

Bus 001 Device 005: ID 054c:05c2 Sony Corp.

But adb doesn't: :-(

adb devices
List of devices attached

Any hint please?

[Xaphiosis]

I just got the device today and have successfully updated the firmware, applied the root package and then the enable-adb package. I added "0x054C" to ~/.android/adb_usb.ini ... but exactly like rinring, adb devices does not pick up my T1; lsusb shows it fine. Android tools freshly updated, latest firmware installed on T1.

There is a little android dude icon, it says "usb debugging connected", everything looks to be OK, it just doesn't work. Any advice? I'd like to repartition so I can play around with apps

For an unknown (to me) reason, it never works... Seems to be a little bug.

You have to:
- Go to the "little android dude icon"
- Disable "usb debug"
- Enable it again
- It show a new window: Press "accept" o "ok"
- And, now, adb works

You have to do the same procedure every time the USB wire has been disconnected.

However, if you order to reboot from adb or from the T1 device, there is no need to do that. It gets ready instantly, just after the reboot process.
