next IK 3.3: Change in init scripts for latest ST-E USB driver support

[Philippe Langlais]

New USB driver in ST-E ALK 5.57 and higher, doesn't start automatically.
A 1 must be written in /sys/devices/platform/ab8500-i2c.0/ab8500-usb.0/boot_time_device at user space startup.
So in all Ubuntu images we have to add a line like this in a Snowball init script:
if [-f /sys/devices/platform/ab8500-i2c.0/ab8500-usb.0/boot_time_device]; then
     echo 1 > /sys/devices/platform/ab8500-i2c.0/ab8500-usb.0/boot_time_device
fi

And in Android add this line in init.rc (in USB initialization):
write /sys/devices/platform/ab8500-i2c.0/ab8500-usb.0/boot_time_device 1

**********************************************************************
Please use the following workaround until this is resolved
1. Boot up board
2. On console run
echo 1 > /sys/devices/platform/ab8500-i2c.0/ab8500-usb.0/boot_time_device
3. plugin the usb cable

USB will work normally after this

Until the bug is resolved please do a

echo 1 > /sys/devices/platform/ab8500-i2c.0/ab8500-usb.0/boot_time_device

in the console once the board has booted up and plugin the usb cable

Supriya: Please check with Lee Jones on what needs done for Ubuntu and he will guide you.

[Anmar Oueja (anmar)]

Lee Jones will be gone on vacation. Please ping Mathieu since he is around next week.

Kalle: Can you please talk to Supriya about the comment you need to add to the Ubuntu init and update the HWPack accordingly

[supriya karanth (supriya-karanth)]

For android the changes are made and USB is working. Attached is the new "init.st-ericssonsnowballplatform.rc" with the changes.

changes for ubuntu yet to be done

I made the following assumptions:

 * The attribute can be safely set multiple times
 * It supports "0" value to turn it off as well, or at least doesn't crash with it

and pushed:

http://www.igloocommunity.org/gitweb/?p=bsp/snowball-init.git;a=commit;h=969beb4

(yes, I did do that 12 years ago, why do you ask! Doh.)

Package uploaded and published in the PPA.

[Kalle Vahlman (kvahlman)]

Tested with the target kernel (stable-ubuntu-ux500-3.3-1), and found that the initialization order was wrong in the script.

A new package with the fix is uploaded (snowball-init 1.4.1).

[Jayeeta Bandyopadhyay (jayeeta)]

Kalle can we change this the status Fix committed?

[Kalle Vahlman (kvahlman)]

For the ubuntu part, yes.

And judging from the earlier comment for android too.

(Next time we should split the bug into two since it's really confusing to track the status just by comments)
