Hifiberry DAC+ --- Linux 3.12.36 --- snd_soc_pcm512x module #846
Comments

When I build all modules statically but snd-soc-pcm512x/snd-soc-hifiberry-dacplus the error looks like this: modprobe snd_soc_pcm512x Jan 1 00:00:40 juplym kern.err kernel: [ 40.223460] pcm512x 1-004d: Failed to get supply 'AVDD': -517 AVDD supply: have i missed some power modules? |
|
We don't use regulators on Raspberry Pi - try removing OF_REGULATOR from your config. |
|
Correction - that should have been CONFIG_REGULATOR. |
|
Thanks, after removing pcm512x loads: [ 45.054314] pcm512x 1-004d: No SCLK, using BCLK: -2 But now the final DAC+ driver fails toload: cat /lib/modules/3.12.36-juplym/modules.builtin | grep i2s Is maybe a wrong name used in snd-rpi-hifiberry-dacplus? |
|
What do |
|
Only above error message multiple times: #dmesg|grep i2s
[ 1.842250] snd-rpi-hifiberry-dacplus snd-rpi-hifiberry-dacplus.0: ASoC: CPU DAI bcm2708-i2s.0
...
#dmesg|grep i2c
[ 1.710450] i2c /dev entries driver

[ 1.718109] bcm2708_i2c_init_pinmode(1,3)
[ 1.722708] bcm2708_i2c bcm2708_i2c.1: BSC1 Controller at 0x20804000 (irq 79) (baudrate 100000)What does '.0' mean at the end of bcm2708-i2s.0? I2S bus 0? There is also no i2s in /dev, only i2c-1. |
|
And Unfortunately the i2s module is silent during a successful boot, and there is no equivalent to spidev or i2c-dev that creates /dev/ entries. I can't spend any more time on this, since you are creating a non-standard configuration, but I suggest you try using bcmrpi_defconfig, verify that it works, then work out what the significant differences are. |
|
All is build statically, so lsmod shows nothing. |
|
Note that it is normal to get some -517/probe deferral "errors" because load order is not guaranteed, but eventually all the components should be ready and the ALSA device will be created. |
|
OK, I've build with bcmrpi_defconfig and after startup only the module ipv6 is loaded. # modprobe -v i2c-bcm2708
# modprobe -v snd-soc-pcm512x
# modprobe -v snd-soc-bcm2708-i2s

Seems static modules are broken. I've checked if here is a .o file for each .ko module when module support is disabled. All drivers are there but loading fails. So I switched to loadable modules and use this modules: regmap-mmio
regmap-i2c
regmap-spi
i2c-bcm2708
spi-bcm2708

snd
snd-timer

Pull drm fixes from Dave Airlie:
"Pre-LCA pull request I'm not sure how things will look next week,
myself and Daniel are at LCA and I'm speaking quite late, so if I get
my talk finished I'll probably process fixes.
This week has a bunch of i915 fixes, some amdgpu fixes, one sun4i, one
core MST, and one core fb_helper fix. More details below:
core:
- mst Fix NO_STOP_BIT bit offset (Wayne)
fb_helper:
- fb_helper: Fix bits_per_pixel param set behavior to round up
(Geert)
sun4i:
- Fix RGB_DIV clock min divider on old hardware (Chen-Yu)
amdgpu:
- Stability fix for raven
- Reduce pixel encoding to if max clock is exceeded on HDMI to allow
additional high res modes
- enable DRIVER_SYNCOBJ_TIMELINE for amdgpu
i915:
- Fix GitLab issue #446 causing GPU hangs: Do not restore invalid RS
state
- Fix GitLab issue #846: Restore coarse power gating that was
disabled by initial RC66 context corruption security fixes.
- Revert f6ec948 ("drm/i915: extend audio CDCLK>=2*BCLK
constraint to more platforms") to avoid screen flicker
- Fix to fill in unitialized uabi_instance in virtual engine uAPI
- Add two missing W/As for ICL and EHL"

Has someone an idea what’s going on?
I see no errors using Volumio (3.18), but I assume it could also work with 3.12
