I did see that. I'll keep it in mind when I try to get the rest of my cape up 
and running on 4.4.x.

Re: [beagleboard] My overlay can't find clk_mcasp0

[William Hermans]

You're welcome Rick, and hey it will benefit me too in the future. Also
just to make sure you notice I switched back to 4.1.x

william@beaglebone:~$ uname -r
4.1.18-bone-rt-r19

The problem with 4.4.x is that I've been gettign all kinds of strange
behavior from it, that I could not nail down. Then today( maybe you saw my
posts ) I was able to finally nail down a specific issue with capemgr. I'm
not sure what eactly is causing the problem, but there is a problem there
*somewhere*.

So for now, I'm back to 4.1.x

Progress. I was able to get teh audio cape to load in 4.1.x.

I used your device tree board file exactly Rick, with one modification.

#include "am33xx.dtsi"
#include "am335x-bone-common.dtsi"

The other two includes were removed. The rest of your source file is
exactly the same. But the am33xx-es2.dtsi include
file looked pretty much useless to me for this end goal. Looked like
it had mostly to do with voltage / processor frequency
scaling. Since I did not know if that was a 4.4.x specific feature, I
just removed the include.

I don't have the BBB connected at the moment, but if I don't get you the

Re: [beagleboard] My overlay can't find clk_mcasp0

[Rafael Vega]

I've made some progress but I still can't get any sound from the codec. I 
tried the two approaches suggested by Rick M earlier on this thread:

1) To use this  dtb by Rick M and the audio 
cape overlay, and 2) to use this 
 
dtb (by RobertCNelson) with no overlay. In both cases I have the same 
apparent outcome: I can see I2C and I2S signals being driven by the BBB 
when I use aplay or speaker-test but I can't see any analog signal coming 
out of the codec.

I have played around with alsamixer, I have deleted 
/var/lib/alsa/asound.state, used the one from here 

 
and no luck... 

I guess the next step would be to check the driver code and the codec 
datasheet to try to figure out what might be wrong. I found the code for 
the driver here 
 
(is that it?) but I have no experience in kernel-land development so I'm 
not sure what the compiling/debugging workflow would be...  My initial 
questions are:

1. How do you compile and install the driver/module without recompiling and 
installing the whole kernel?
2. How does the driver code integrates with the device tree system? I can't 
see anyting in the driver code that suggests it's taking values or it's 
functions are being called from the dtb or the overlay.
3. What is the simplest 'log' function callable from kernel land and where 
do I see the output? 

Any advice on  this would be appreciated!

:)

Wish I had a physical cape, I'm very good at troubleshooting these sorts of
issues. I'm thinking it's probably in the driver though. No reason, other
than gut instinct.

Well, you know, I wasn't there . . . word of mouth sort of thing.

Anyway, I'll probably just comment out the edma fix file,  and just manualy
load the SPI's later, or . . . actually I do not think we use any of the
SPI modules from the processor.

When I do this, the overlay loads fine and I can see the mcasp0 pins being 
driven by the BBB when I start aplay or speaker-test. However, I can't see 
any analog signals coming out of the codec. May I ask what ALSA or 
alsamixer configuration you are using to achieve output on the left channel?

Thanks for taking me this far!! :)

Yeah, that's the file that's working for me, EXCEPT: I modified my 
am33xx-overlay-edma-fix.dtsi to comment out the two mcasp entries. If I boot 
with that (on 4.4.7-bone-rt-r9), then I can load the BB-BONE-AUDI-02 overlay, 
and then I can use aplay and speaker-test.

At this point, though, the channels are not quite right. Only the left works. 
This is hopefully due to a very badly configured ALSA.

BTW, your buddy surely didn't use my cape; I've only built one, and it's here. 
:-) The last few days I've been using the CircuitCo AudioCape Rev B (the Rev A 
has a different codec). My cape is almost identical to the Rev B, so I'll soon 
try it again.

Re: [beagleboard] My overlay can't find clk_mcasp0

[William Hermans]

Yeah, right now I'm just trying to get the audio cape to load. The audio
cape of our project is actually one of two potential daughter capes, and
we're not in a huge hurry to figure all that out. But I figured since you
all are doing this, now I'd join in and see if i could help or not. Plus,
yes, get our cape working in the process ;)

Also, my buddy tried one of your capes, and it wound up locking his board
up at boot. But the funny thing was, I took his sdcard, and rewrote the
dtb= line myself, and the board still would not boot. I had to revert it to
an older kernel. So yeah, no idea exactly what was going on. Hard to keep
track of what I'm doing, and what he's doing at the same time . . .

Re: [beagleboard] My overlay can't find clk_mcasp0

[Rick Mann]

Yeah, so this was the problem I ran into a few weeks ago. There's a thread on 
it, but I thought the dts I posted addressed it.

Re: [beagleboard] My overlay can't find clk_mcasp0

[William Hermans]

I'm still attempting to get the audio cape overlay to load. Anyone have a
clue as to why it might not work ? Something that did cross my mind is that
perhaps that edma fix include is being included in yet another source file.
Somethign else that is being included.

Yeah, that's very broken..  Here's a quick copy/paste/etc...

https://gist.github.com/RobertCNelson/fe8abb7fe11121f0a8c2c0afb291b339

I'd say it's 95% there, didn't try building it..

Here's my attempt to do what you suggest: 
https://gist.github.com/rvega/aebb225155b7c8990b3593f3a90851eb 
It compiles as am335x-boneblack-audio-fixed.dtb without any error messages, 
I copied the dtb to /boot/dtbs/4.4.7-bone-rt-r9, added  
dtb=am335x-boneblack-audio-fixed.dtb to uEnv.txt and rebooted the board but 
when powering up, the 4 user leds stay lit and the heartbeat never starts. 
No luck booting.

Can anyone spot the error on the dts or suggest a way to get error messages?

That seems reasonable, but I haven't tried it myself. Obviously, you should 
connect to the serial console and see what messages are output there.

Are you able to make it work with my original .dtb and loading the 
BB-BONE-AUDI-02 overlay via capemgr?

I compiled it as am335x-boneblack-audio-fixed.dtb, copied it to 
/boot/dtbs/4.4.7-bone-rt-r9 and added # 
dtb=am335x-boneblack-audio-fixed.dtb to /boot/uEnv.txt. When I try to boot 
the board the 4 user leds stay lit. No luck booting.

Can someone spot an error on the dts or suggest a way to find error 
messages?

Thanks!

Re: [beagleboard] My overlay can't find clk_mcasp0

[evilwulfie]

So much i dont know.


rick or robert where might i get this file ?

am33xx-es2.dtsi

Its not in the dts-rebuilder i installed and Ricks new dts file seems to
require it to compile

src/arm/am335x-boneblack-audio-emmc.dts:11:27: fatal error:
am33xx-es2.dtsi: No such file or directory

Designing hardware is so much more easier :P

I remember firmware in the old days  patch the code and burn some
bipolar proms  install and continue

Re: [beagleboard] My overlay can't find clk_mcasp0

[William Hermans]

Is the audio cape another one of those eeprom capes that need physical
hardware in order to load properly ? Because I do not have the physical
cape.

Re: [beagleboard] My overlay can't find clk_mcasp0

[William Hermans]

I'm still seeing this:

pin 82 (44e10948.0): 4a101000.mdio (GPIO UNCLAIMED) function
davinci_mdio_default group davinci_mdio_default
pin 83 (44e1094c.0): 4a101000.mdio (GPIO UNCLAIMED) function
davinci_mdio_default group davinci_mdio_default

Are these pins required for the ethernet MAC ? And are they interfering
with the McASP module ?

For the record, I edited recompiled the same main board file as evilwulfie,
and . . .

william@beaglebone:~$ sudo sh -c "echo 'BB-BONE-AUDI-02' >
/sys/devices/platform/bone_capemgr/slots"
william@beaglebone:~$ cat /sys/devices/platform/bone_capemgr/slots

 1: PF  -1

Actually, dahm it, I forgot to edit uEnv.txt . . .

4.4.x is also an lts, the overlay patches between v4.1.x and v4.4.x are
almost identical..

We're trying to determine that here. Were you able to get the audio cape
loaded at all with a 4.1.x kernel ? We really do not want to move outside
of a "stable" kernel if at all possible.

Just playing along here . . . I thought maybe HDMI had to be loaded to load

Re: [beagleboard] My overlay can't find clk_mcasp0

[evilwulfie]

very interesting. after removing the eDMA fix and recompiling we still
cant load the audio cape

sudo cat /sys/kernel/debug/pinctrl/44e10800.pinmux/pinmux-pins

stuff removed for clarity


pin 82 (44e10948.0): 4a101000.mdio (GPIO UNCLAIMED) function
davinci_mdio_default group davinci_mdio_default
pin 83 (44e1094c.0): 4a101000.mdio (GPIO UNCLAIMED) function
davinci_mdio_default group davinci_mdio_default


I think this is the reason.

Re: [beagleboard] My overlay can't find clk_mcasp0

[Rick Mann]

The DTB I posted includes am33xx-overlay-edma-fix.dtsi, which enables mcasp0 
and mcasp1. This causes the snd_soc_davinci_mcasp driver to load, and it 
configures itself at that time. But that DTB doesn't have the necessary entries 
for that driver to properly configure. When you then later load the overlay 
(e.g. BB-BONE-AUDI-02), the driver ignores the new entries.

There are a couple of solutions. The best is to move all the remaining entries 
that are in the overlay into a new .dts file based on this < 
http://pastebin.com/Wja7ZQRk>, compile that, and load it at boot.

Or, compile this .dts  and load it at boot, then 
load the cape overlay. The drawback to this is (apparently) the eDMA slots 
won't get assigned properly for mcasp, so there might be issues down the road. 
It seems to work as-is for me, but I don't know if there is higher CPU loading, 
or what. I don't really understand the eDMA issues.

Re: [beagleboard] My overlay can't find clk_mcasp0

[Rafael Vega]

Thanks Rick!

When you say the driver ends up not being properly configured when you load 
the overlay, does that mean I should not load the overlay? Or should I load 
it and expect problems? which problems?

I had to make one that also enabled the emmc:

http://pastebin.com/Wja7ZQRk

Note that there's a problem with that file. It includes 
am33xx-overlay-edma-fix.dtsi, which causes the mcasp driver to load first, and 
it ends up not being properly configured when you load the overlay. I'll be 
writing a full DTS for my project, rather than use the overlay mechanism, but 
for now that's how I do it.

Does this mean that the board won't be able to boot from the emmc when

Re: [beagleboard] My overlay can't find clk_mcasp0

[Rafael Vega]

I'm trying to use the same codec as Rick but I need to use a 'bone-rt' 
kernel (old PRU api and PREEMPT). Can you tell me what/where the base  
*.dtb is and how to compile it when using a bone-rt kernel?
Thanks!

Augh, right. So, how do I get past this situation? Do I need to boot from SD 
card, or can I fix it via initramfs?

I tried googling, but didn't have much luck.

Oh, I'm on a BB Green. Should that have been am335x-bonegreen-audio.dtb?

I'm in initramfs, but I'm not sure how to find the uEnv.txt file to edit it.

Thanks, just found it (while my manual build was running :-) ). Good thing, 
too; I forgot how to go from building the kernel to installing the image, dtbs, 
modules, and headers :-)

Should that be available in apt, or do I need to git pull and build it myself? 
I tried "apt-get update && apt-get install -y linux-image-4.4.6-bone-rt-r7" but 
no luck. Maybe it just takes a while to show up?

But maybe I can piggyback off the one you show there.

Switch to r7, just pushed it out this morning.

Just a bug in the clock driver, the dynamic overlay changes is still very
fragile. In most cases moving the driver as a module vs built-in, fixes it
right up.. Except this is the clock driver, it needs to be built in..

Thanks, Robert. I'll give that a shot. I'm not immediately sure what my current 
base *.dtb is, nor how to build a new one and specify that be used. But maybe I 
can piggyback off the one you show there.

Out of curiosity, why can't this be done as an overlay (to help me understand 
the Device Tree better)?

Thanks!

btw, the one thing i haven't tried, have everything in the clk defined

side note, we just got audio (cape audio rev b) working a few weeks back,

You need to add this to your base *.dtb:

https://github.com/RobertCNelson/dtb-rebuilder/blob/4.1-ti/src/arm/am335x-boneblack-audio.dts#L17-L28

(that section can not be loaded as overlay, it must be in your base dtb)

[beagleboard] My overlay can't find clk_mcasp0

[Rick Mann]

I'm trying to get my audio cape to work (which is nearly identical to the cape 
that was available for sale). I've had it working to some level of success with 
past kernels (3.1.18), but now I'm on 4.4.6. My existing DTS didn't work, so 
I'm looking at how the BB-BONE-AUDI-02 DTS is written.

One of the differences is that it doesn't explicitly call out the McASP clock 
frequency like the older one did. Instead, it seems to refer to clk_mcasp0. But 
when I copy the same code into my DTS, I get:

[  103.180866] of_resolve_phandles: Could not find symbol 'clk_mcasp0'
[  103.187269] bone_capemgr bone_capemgr: slot #4: Failed to resolve tree

I found it defined by grepping /boot/dtbs. It's in 
/boot/dtbs/4.4.6-bone-rt-r6/am335x-abbbi.dtb. Where can I find the source files 
for these DTBs?

Is this dtb part of what's loaded by default in 4.4.6-bone-rt-r6? If not, can I 
copy the definition into my 

FWIW, here's my DTS and some output from dmesg: http://pastebin.com/niDkWdWV
