In previous post (How-to set up network audio server based on PulseAudio and auto-discovered via Avahi) I’ve wrote details how I set up network audio-server. Actually I’m using cubietruck there.

Now I want to post how I installed F22 and get audio card working (it’s not trivial).

Cubietruck terminal

Requirements

  • Fedora 22 minimal image from dl.fedoraproject.org
  • Installed package uboot-images-armv7
  • Few hours (microsd really sloow)

Write Fedora and u-boot images to microSD card:

# xzcat -T 4 Fedora-Minimal-armhfp-22-3-sda.raw.xz | dd of=/dev/mmcblk0; sync
# dd if=/usr/share/uboot/Cubietruck/u-boot-sunxi-with-spl.bin of=/dev/mmcblk0 bs=1024 seek=8 conv=fsync,notrunc

Read partition table, mount and remove root password:

# partprobe /dev/mmcblk0
# mount /dev/mmcblk0p3 /mnt
# vim /mnt/etc/passwd

And just remove x from root’s line.

Now we can insert card into cubietruck and power it on. It will not load fully because initial-setup-text.service will run on serial console. So just press Ctrl+Alt+F2 and login as root. Now we need to disable initial-setup and set root password.

# systemctl disable initial-setup-text.service
# passwd

Okay, fedora works and we can use it. Now second part about sound. Upstream kernel as for 4.2-rc4 doesn’t support sunxi-codec driver. Maxime Ripard has pointed me to his fork of linux kernel with some patches which adds support for sunxi-codec:

* f968132 Add cubieboard2 audio codec
* 8c1b463 codec: changes for Mele A1000
* 42ac277 ARM: sun7i: dt: enable audio codec on Cubietruck
* 4da9e56 ARM: sun7i: dt: Add sunxi codec device node
* 68d66ec ASoC: sunxi: add support for the on-chip codec on early Allwinner SoCs
* 93f01ab dma: sun4i: Add support for the DMA engine on sun[457]i SoCs
* 47c8977 ARM: sun7i: Add mod1 clock nodes
* ff52fcc ARM: sunxi: Add codec clock support
* 3233580 ARM: sunxi: Add PLL2 support
* 080077c clk: sunxi: mod1 clock support
* 048d967 clk: sunxi: codec clock support
* 7017705 clk: sunxi: Add a driver for the PLL2
* 883efa6 clk: Add a basic factor clock

So I just took Fedora’s kernel git tree, applied patches, enabled some options in kernel, built it in Koji for F22 and installed on cubietruck. Unfortunately, network driver doesn’t work in 4.2-rc4 due to BUG. It’s not fixed in upstream, only way to have network — have USB Network card. I’m not sure if that patches going to 4.3, but I’m sure we will get it in upstream at some point.
