Renderer-Controllers for [Media Centre][1].

Type
:   Single-board Computer

OS
:   OSMC, Dietpi

# Configuration

# OSMC Configuration

## Hostname

sudo hostname lounge

Edit `/etc/hostname`:

lounge

(or "ballroom", etc)

## kodi and systemd

sudo systemctl stop mediacenter
    sudo systemctl start mediacenter

## Sound (Bullseye)
Bullseye switch to the open-source vc4-kms-v3d HDMI driver which includes audio
support but does not allow for ALSA dmixing (because it supports IEC985 but not PCM).

Revert to vc4-fkms-v3d (fake KMS using firmware) and reenable bcm2835 audio:

/boot/config-user.txt:
```
dtoverlay=vc4-fkms-v3d
max_framebuffers=2
dtparam=audio=on
```

/boot/cmdline.txt:
```
snd_bcm2835.enable_headphones=1 snd_bcm2835.enable_hdmi=1 snd_bcm2835.enable_compat_alsa=0
```

## SNMP

**GeSHi Error:** GeSHi could not find the language bashapt-get (using path /var/www/data/mark/pmwiki/cookbook/geshi/geshi/) (code 2)

### Installing

apt-get install v4l-utils libjpeg9

## Fixing Blue Screen

Blue screen (on Study TV after power cycle).

Workaround:

tvservice -o
    tvservice -p
    sudo systemctl restart mediacenter

See [related OSMC issue][10].

Try boosting hdmi in RPi config: `/boot/config.txt`

config_hdmi_boost=6

## Qemu

Basic Raspberry PI kernel and rootfs here:

*   <https://people.debian.org/~aurel32/qemu/armel/>

### Exiting

Ctrl-x

Or through screen: Ctrl-a,a,x

### Running

Need to redirect the console if running via SSH:

qemu-system-arm \
      -M versatilepb \
      -nographic \
      -kernel vmlinuz-3.2.0-4-versatile \
      -initrd initrd.img-3.2.0-4-versatile \
      -hda debian_wheezy_armel_standard.qcow2 \
      -append "root=/dev/sda1 console=ttyAMA0 console=ttyS0"

For initial boot (pre passwd setup) add `init=/bin/bash` or `init=/bin/sh` depending on what's in the root image.

### Qemu SCSI bug

A qemu bug (pre 1.5) leaves `qemu-system-arm` in a loop attempting to reset the SCSI bus (I think).

Luckily [Wheezy backports has qemu-2.1][13].

apt-get -t wheezy-backports install qemu-system-arm

## Qemu Raspbian

*   <http://xecdesign.com/qemu-emulating-raspberry-pi-the-easy-way/> 
*   Need qemu >= 1.5

Kernel
:   <http://xecdesign.com/downloads/linux-qemu/kernel-qemu>

Rootfs
:   [Latest RaspBMC image][14]) from <http://downloads.raspberrypi.org>

```shell
#!/bin/bash

KERNEL=xec-kernel
ROOT=raspbmc0.img

qemu-system-arm \
    -cpu arm1176 \
    -nographic \
    -kernel "$KERNEL" \
    -m 128 \
    -M versatilepb -no-reboot \
    -hda "$ROOT" \
    -append "root=/dev/sda2 panic=1 rootfstype=ext4 rw"

```

## Other Methods

### Debootstrap Chroot

"Unable to reserve guest address space"

### multistrap

Generates disk image. chroot fails with the same memory allocation failure.

### Cross Compiling

*   <http://hertaville.com/2012/09/28/development-environment-raspberry-pi-cross-compiler/> 
*   <http://www.openframeworks.cc/setup/raspberrypi/Raspberry-Pi-Cross-compiling-guide.html>

Use `gcc-linaro-arm-linux-gnueabihf-raspbian-x64` for x64 host.

Gave up with pkg-config problems after a while.
