How to install Pogoplug software on V2 Plug

')


I suppose it isnt as simple as changinging ioctl to unlocked_ioctl. Some professional input would be nice

I am a big fool. I've been trying to get xce for pogoplug mobile to run on V2 Just noticed I had downloaded the wrong source.

Ok, this one seems to work.
Here's patch:

Module is attached. I'll be away for a week so test the hell out of it
It goes into /usr/local/cloudengines/bin and replaces the existing xce.ko
EDIT: This module is compiled for kernel 3.1.10-11-ARCH and will only work with this version. If there's an update, this module will need to be recompiled. Check your kernel version if the module doesn't load (uname -a)

$this->bbcode_second_pass_quote('moonman', 'I') am a big fool. I've been trying to get xce for pogoplug mobile to run on V2 Just noticed I had downloaded the wrong source.

[WarheadsSE]

I think I'll source mine up on GitHub sometime this week, it was an OS'd release anyways. Might have to make a few subtrees for oxnas/kirkwood, and see about pulling the difference for the newer platforms vs what I might have based mine on. Admittedly, I neutered all the gpio calls for the kirkwood one I built. Sadly, I am still attempting to sort out getting it running as a user other than root.

$this->bbcode_second_pass_quote('rty', '
')By the way, will you be updating the steps you outlined on post #1 of this thread?

[rty]

Thank you very much Moonman!

I got it to work but my Pogoplug V2 (E02) rebooted by itself twice after that (over a period of 1-2 hours). I did replace the xce.ko in /usr/localengines/bin with yours. In your previous post, you mentioned about a patch. Any patch script I have to run? By the way, both random reboot events took place with my SSH terminal session active and my webbrowser displaying disk content over Mypogoplug.com.

Here are some of my observations on my V2 (E02):

1. As you previously noted, hbplug.conf didn't exist in /usr/local/cloudengines/bin.

I created one and filled in as follows

$this->bbcode_second_pass_code('', '
#example below: vfsdir<number>=<name>,<path>
vfsdir0=plugdata,/public
installdir=/usr/local/cloudengines
datadir=.
nohotplug=1
')

I left the svcid line out as WarheadSE suggested. It was inserted automatically afterward.
vfsdir0 line, however, must not be commented out.

2. After completing all the steps, I found another copy of hbplug.conf in my /root directory. I am not sure how it was created or whether I can safely delete it or not. Also the svcid number found inside is different from the one in /usr/local/cloudengines/bin/hbplug.conf.

I am not sure if this helps but everytime I start the engine with the command "rc.d start pogoplug", I get error messages even though the engine works.

I upgraded to 3.1.10-11-ARCH (#1 PREEMPT Mon May 21 05:59:32 UTC 2012 armv5tel GNU/Linux) and tried to compile xce.ko myself. Ended up with this error instead:
