Looking for a guru
« on: October 15, 2013, 10:41:39 AM »
Hi Team,

I am not sure if it's ok to "advertise" this on the forum instead of Elance or the likes, but as an avid linux guy I really would rather start by asking those I know could really lend a hand and help me.

Essentially I'm looking for someone that can assist me with a very custom image of TC.

I am currently running "standard" raspbian image and am very familiar with that version including having complied a few packages for our application BUT now I'm keen to migrate our solution to TC as TC offers lots of benefits.

So, without "posting an official advert" I'm keen to see if there are any enthusiasts here that would be keen on assisting me with the task?

I'm more than happy to pay, I'd just like to ensure I learn along the way so hence I'm not keen to go the Elance route just yet.

Any takers welcome :)

Looking forward to it.

Bye for now
Dean

Hi bmarkus - Thanks for the speedy reply.

Sure, I can detail a little more :)

The project is audio based and involves using sun embedded java.

Our current system runs on raspbian with jdk1.8.0 embedded but also uses a few other tricks to do final audio play out.

This is done using a small utility called "der mix d" or Der Mix Daemon (basically like MPD but allows for cross fading and normalization + links into the Java app via "calls")

Then there are a few other features I need to get working. These being pretty basic, but guidance would be appreciated. Such as :

rsync
vtun
static IP addresses and multiple virtual NIC's
shorewall firewall

Then I think it really is a case of just understanding the TC setup 100%.

For example, I already have Java installed and persisting so in fact our app actually already starts but it's currently throwing a few errors that I suspect are DerMixD related. For now I've literally copied the compiled binary across from a raspbian version so I think there must be some missing .so files.

I think the biggest help I need is setting up an excellent foundation for absolute recovery of the system. IOW, ideally I would like to partition the SD card into serval partitions so that :

1) There is always a "backup" fail safe image / partition for absolute recovery to default system.
2) The "normal" mydata image is used on reboots (this I have working)
3) Swap is used (I think I have this working too ;)
4) Another partition is mounted on the "home" folder of a user and is basically the "data store" for audio files
5) The boot partition as "normal" with a few tweaks to ensure we use all RAM

Hope this gives you some idea and again really looking forward to working with TC to deliver our solution.

Thanks and chat when you can,

There are few components are not in the repo yet (rsync, vtun, jdk, etc.) but they can be added, it is not a problem. They are generic programs, so there is a need for them.

Regarding partitions, TC is just the same as any other LINUX system. You can partition your SD card as you wish; if you want to be flexible, even you can use LVM2.

The key part is to learn TC, persistent setup, extensions, etc.

But for sure it can be done with piCore.
