Users / 'Diskless' Raspberry Pis are out in the wild!
« on: September 21, 2016, 01:43:15 am »
Hey everyone!  I wanted to pass on some of the recent work I've been doing in relation to the Raspberry Pis.

It's been a long slog bringing the system to the RPi line of systems.  In the original LMCE release for the RPi I had spent 2 months hacking u-boot to provide a really robust 'PXE like' boot process for the RPi in LMCE.  It was intense and required understanding and programing u-boot for low-level memory access to pass boot parameters (ATAGS) properly to the linux kernel.  When the RPi2 was released the hardware had changed significantly and the broadcom SOC was upgraded to a multi-core cpu and armv7 rather than the older armv6 architecture.  Due to the architecture changes in the SOC u-boot failed to work with the new Raspberries.  So I revived the old, old concept of disked Media Directors for the RPi2.  This worked well as long as the power didn't go out (which meant you would have to re-write the sdcard and let the system re-install all the software packages again.)  With the RPi foundation's recent announcement of netboot capability (https://www.raspberrypi.org/blog/pi-3-booting-part-ii-ethernet-all-the-awesome/) we have a new way to boot all Raspberry Pi B's (1, 2 and 3).

Head on over to http://wiki.linuxmce.org/index.php/RaspberryPi to read about how to setup a network booting RPi Media Director.

Keep in mind that the RPi foundation (and myself) still consider this to be very experimental.

Have fun!

Thanks!  As soon as I have a few minutes I'll take a look.

Installation issues / Re: no sound over hdmi

As we've mentioned there is really no one maintaining mythtv.  Patches are welcome.  Otherwise it sounds like a mismatch in settings for xine.  You have not provided any information about your video card hardware or card id.  I'm aware of the xine config, but it is extremely variable depending on hardware.

As posde indicates there is a fix for this in the repository now.  I've tested this now with multiple PCs and PXE booting PCs and RPis should both be working.  Keep in mind that the rpi foundation considers PXE booting to be very much in beta stage.  All said it's working well here.

We don't use github.  Our repository is available at: https://git.linuxmce.org

See the sticky in the developers forum about gaining access to it.

Just a comment from above about Host and DBHostname,  on the core I can understand local host as value, but on MDs it must be dcerouter ( or else on mythtv-setup one gets the recurring language screen, or the mythtv-backend refuses to start)

Ok, include that info in the ticket.  It's being set in mysql.txt to dcerouter but not currently in config.xml.  Thanks for looking into this!

I can help with script changes (if required) but cannot test as I don't have anything setup to test with.  Let me see if I can respond to a couple of points:

On the CORE, everything works great..   the /etc/mythtv/config.xml file and the /etc/mythtv/mysql.txt work great.

Good to know, thanks for verifying that.

On the MD:  there are several things Ive noticed:
     1.    the user mythtv needs to have the same uid and gid as the CORE's mythtv user (because the home folder is a nfs mount from the core)

hmm, I thought that ypserv/ypclient would be taking care of this.  That may need to be looked at to see if it's working properly or not.  The MDs *should* have all the same users as the core, at the same UID/GID.  Something in NIS may not be working properly?
**EDIT: NIS only deals with additional users, not system created users it seems. 

     2.    Each MD gets a unique <Password> in the /etc/mythtv/config.xml (by default on mythtv install i am assuming)  This <Password> can stay
            what it is, but also needs to be the same as the DBPassword in the /etc/mythtv/mysql.txt file,   AND it needs to be the same password for
            the mysql user mythtv@192.168.1.xx (MD iP address).

When the pluto-mythtv-player package is installed it attempts to copy the core's config.xml and mysql.txt file, however the package is installed into a chroot and likely can't get the files initially.  We'll need to look at a way to trigger a package re-configure during firstboot of the MD or something.

     3.    On any MD, the <Host> in /etc/mythtv/config.xml  and DBHostname in /etc/mythtv/mysql.txt NEEDS to be dcerouter

That is should be as it should be a duplicate of the core's file when things work as they are currently designed.

Hope this helps.

Very much.  I would ask that you open a ticket/issue in our git system so that we can reference this and track any changes related to it.  Add the above information to the ticket please.  Check the sticky at the top of the developers section on getting access to git.linuxmce.org

Thanks!

Well, I tried adding the Pioneer kuro and I'm not getting any codes here.  Shit.

Any time you edit a DT and choose to edit ruby codes the associated commands are fetched from the schema server.  IR codes are also updated when certain packages are updated.  I forget which ones at the moment.  Try a few dts and see if you get codes for any of them

Rather than rebuilding the template it should be determined why it's not retrieving.

Why are you building a new denon template?  We have working serial and Ethernet templates.
