AM5708: Linux: McASP5 audio not working

Scott Lin2

Part Number: AM5708
Other Parts Discussed in Thread: AM5728, DRA722, TSC2007

Hi,

We have developed a custom board with AM5708 processor using ti-processor-sdk-linux-am57xx-evm-05.03.00.07.
We are having McASP5 interface in the board and for MCLK we have connected to H5 ball of AM5708 processor.
Could you help us to make the sound work?

Pinmux in uboot we set
{GPMC_ADVN_ALE, (M2 | PIN_OUTPUT)}, /* gpmc_advn_ale.clkout2 *//* audio_master_clk */
{XREF_CLK0, (M4 | PIN_OUTPUT)}, /* xref_clk0.mcasp5_ahclkx */
{MCASP5_ACLKX, (M0 | PIN_OUTPUT)}, /* mcasp5_aclkx.mcasp5_aclkx */
{MCASP5_FSX, (M0 | PIN_OUTPUT)}, /* mcasp5_fsx.mcasp5_fsx */
{MCASP5_AXR0, (M0 | PIN_OUTPUT)}, /* mcasp5_axr0.mcasp5_axr0 */

am571x-idk.dts we add

sound0: sound@0 {
compatible = "simple-audio-card";
simple-audio-card,name = "DRA7xx-EVM";
simple-audio-card,widgets =
"Headphone", "Headphone Jack",

Hi Scott Lin2,

Why is MCLK connected to H5 Ball instead of J25 Ball ? J25(mcasp5_ahclkx) is the Master clock

0 Dwarakesh Radhakrishnan over 3 years ago in reply to Dwarakesh Radhakrishnan

Guru 13620 points

Hi,

Also from device tree configuration, input to mcasp5_ahclkx from Auxiliary oscillator OSC1 sysclk_in. Is OSC1 populated in the hardware ? Can you share the schematics snippet ?

0 William Hsieh1 over 3 years ago in reply to Dwarakesh Radhakrishnan

1. AM5728 EVM use clkout2 as the MCLK function, so we follow it too.

But we still reserve the MCASP5_AHCLK test point, and we could change the MCLK pin tor MCASP5_AHCLK

2. We put the 25MHz crystal on OSC1.

0 Dwarakesh Radhakrishnan over 3 years ago in reply to William Hsieh1

Guru 13620 points

Hi William,

1. Let me check and confirm if clkout2 can be used instead of AHCLKX

2. Can you please share the schematics snippet of MCASP connections too ?

3. Have you probed AHCLKX(clkout2), ACLKX(bit clock) and FSx(word clock) when there is data transfer(music is being played) and able to see the clocks in oscilloscope ? What are the values ?

0 William Hsieh1 over 3 years ago in reply to Dwarakesh Radhakrishnan

Intellectual 370 points

Hi Dwarakesh R.,

AHCLKX no signal

ACLKX frequency 781.3KHz

FSX frequency 24.41KHz

Clkout2 frequency 20MHz

Guru 13620 points

Hi Willaim,

AFAIK, I have seen 24.576MHz clock for MCLK for multiples of 48KHz sampling clock. 22.5792MHz for 44.1KHz sampling clock. So a 24.476MHz or 22.5792MHz to OSC1 would be generally connected.

48 KHz x 512 = 24.576 MHz

44.1 KHz x 512 = 22.5792 MHz

I am seeing sampling clock is 24.41 KHz in your case:

24.41 KHz x 512 = 12.5 MHz, which means it is picking up 25 MHz instead of 20 MHz assigned MCLK.

I see two concerns:

1. If MCLK of 20MHz is correct for the AK4432 ?

2. Generally OSC1 would be 22.5792 MHz or 24.576 MHz and would use OSC1 to derive the I2S word clock and bit clock, which is also not happening.

For using 20MHz, can you try the below and check if FSx and ACLKX change

sound0_master: simple-audio-card,cpu {
sound-dai = <&mcasp5>;
system-clock-frequency = <20000000>;
};

1. If MCLK of 20MHz is correct for the AK4432 ?

20MHz is not correct and I put the clock table as below.

After changing the OSC1 crystal to 24.576MHz, the frequency setting is change.

AHCLKX no signal

ACLKX frequency 768KHz

FSX frequency 24KHz

Clkout2 frequency 20MHz

Hi William,

Though OSC1 is 24.576 MHz, still looks like OSC0 20MHz is used as source for clkout2. Can you please try the following:

&i2c2 {
status = "okay";
clock-frequency = <400000>;

audio: audio-codec@19 {
#sound-dai-cells = <0>;
compatible = "akm,ak4432";
reg = <0x19>;

+assigned-clocks = <&clkoutmux2_clk_mux>;

+assigned-clock-parents = <&sys_clk2_dclk_div>;

};
};

Try adding the above lines and check. Also please revert back system-clock-frequency = <20000000> to system-clock-frequency = <24576000>, since you have changed OSC1 to 24.576MHz.

Hi Dwarakesh R.,

After applying this change, CLKOUT2 is 24.576MHz now.

How could we set FSX to 48KHz and ALCKX to 3.072MHz?

Thanks.

Best regards,

William.

Hi William,

Also try the attached file and commands as below

# aplay sample06.wav -vvv

0 Dwarakesh Radhakrishnan over 3 years ago in reply to William Hsieh1

Guru 13620 points

How could we set FSX to 48KHz and ALCKX to 3.072MHz?

This depends on the audio being played. Suppose you play audio of 32-bit, stereo and 48KHz, then you would get a

ACLKX = 32 x 48KHz x 2 = 3.072 MHz

FSx = 48KHz

Since you are playing mono, 8-bit, 8000, you should get:

ACLKX = 8 x 8KHz x 1 = 640KHz

FSx = 8KHz

But looks like there is no support for playing such a low parameters audio in MCASP. Thats why you get this error "Too fast reference clock (24576000)". Thats why I sent you a 16-bit, Mono, 48KHz audio to try and play. Please give it a try.

Hi Dwarakesh R.,

By playing your sampl06.wav file still get NO sound...

ACLKX frequency is 1.535MHz

FSX frequency is 48KHz

Hi Scott,

Do you see AXR0 toggling in scope, when music is being played ? If so I then strongly suspect on the Codec side settings. Hope AVDD is given and is available to Codec. You can also probe on the analog side of Codec to see if any waves are there.

0 William Hsieh1 over 3 years ago in reply to Dwarakesh Radhakrishnan

Hi Dwarakesh R.,

AXR0 is toggling and the AVDD & VCOM &LDOO voltage is fine but the analog output still don't work.

Best regards,

William.

Hi William,

What is the voltage levels on pins like P/S, I2CFIL, etc ?

0 William Hsieh1 over 3 years ago in reply to Dwarakesh Radhakrishnan

Intellectual 370 points

Hi Dwarakesh R.,

I2CFIL and P/S are the configuration pins and both pulled down.

I2C & CLOCK & data working voltage is 3.3V.

We simultaneously issue this situation to AKM side for further disscussion.

Best regards,

William.

Hi Dwarakesh R.

=> But looks like there is no support for playing such a low parameters audio in MCASP. Thats why you get this error "Too fast reference clock (24576000)". Thats why I sent you a 16-bit, Mono, 48KHz audio to try and play. Please give it a try.

Is it limited by am5708 or our Codec for playing 8 bit, Rate 8000 Hz, Mono audio?

Regards,

Scott

Hi Scott,

I checked and it looks like depnds on this value system-clock-frequency = <24576000>; to a lower value in dts e.g.

system-clock-frequency = <4096000> and then try playing 8KHz audio

Hi Dwarakesh R.

Sorry I pressed the wrong button.

after we apply system-clock-frequency = <4096000> and then try playing 8KHz audio

the frequency is wrong, audio sounds like noise

when playing Unsigned 8 bit, Rate 8000 Hz, Mono

ACLKX frequency is 1.536MHz

FSX frequency is 48KHz

Clkout2 frequency 24.576MHz

when playing Signed 16 bit Little Endian, Rate 48000 Hz, Mono which is given by you sample06.wav

ACLKX frequency is 6.144MHz

FSX frequency is 192KHz

Clkout2 frequency 24.576MHz

Clkout2 didn't change when modify to

sound0_master: simple-audio-card,cpu {
sound-dai = <&mcasp5>;
system-clock-frequency = <4096000>;
};

Hi Scott,

Can you please try the below. I am not sure if this would change, let me look into further, but just a quick try:

&i2c2 {
status = "okay";
clock-frequency = <400000>;

audio: audio-codec@19 {
#sound-dai-cells = <0>;
compatible = "akm,ak4432";
reg = <0x19>;

assigned-clocks = <&clkoutmux2_clk_mux>;

assigned-clock-parents = <&sys_clk2_dclk_div>;

+ assigned-clock-rates = <4096000>;

};
};

and in the below way too:

&mcasp5 {
#sound-dai-cells = <0>;
assigned-clocks = <&mcasp5_ahclkx_mux>;
assigned-clock-parents = <&sys_clkin2>;

+ assigned-clock-rates = <4096000>;

status = "okay";

op-mode = <0>; /* MCASP_IIS_MODE */
tdm-slots = <2>;
/* 4 serializers */
serial-dir = < /* 0: INACTIVE, 1: TX, 2: RX */
1 0 0 0
>;
tx-num-evt = <32>;
rx-num-evt = <32>;
};

Continue to keep the system-clock-frequency = <4096000>;

Hi Scott,

Can you send me the complete logs with dmesg ? What are all the clocks that you see now in scope ?

Try with below command

# aplay test.mp3 -vvv

Hi Dwarakesh R.

The file can not be played, therefore no clock can be measured.

Hi Scott,

There seems to be no obvious errors that I am seeing in this log to narrow down what is the issue. Have you made sure there is no syntax error in dts ?

Also you can remove assigned-clock-rates = <4096000> first under mcasp5 and test. Next you can add this and remove the one under i2c2 and check. Let me know if there is still issues

It seems when using assigned-clock-rates = <4096000>

# aplay test.mp3 -vvv
Playing raw data 'test.mp3' : Unsigned 8 bit, Rate 8000 Hz, Mono
ALSA lib pcm_params.c:2162:(snd1_pcm_hw_refine_slave) Slave PCM not usable
aplay: set_params:1073: Broken configuration for this PCM: no configurations available

Therefore I change to use system-clock-frequency = <4096000> in BOTH sound0_master and &mcasp5

Here is the log and the clocks are

ACLKX frequency is 1.536MHz

FSX frequency is 48KHz

Clkout2 frequency 24.576MHz

Hi Scott/William,

I went through the code. If you need flexible 48KHz, 8Khz etc MCLK depending on the audio being played dynamically then you need to connect J25(mcasp5.ahclkx). J25 is not sending the clock because device tree needs to have a flag like below:

sound0_master: simple-audio-card,cpu {
sound-dai = <&mcasp5>;
system-clock-frequency = <24576000>;

system-clock-direction-out;

};

Please revert back system-clock-frequency from 4096000 to 24576000. Also please monitor the J25(mcasp5.ahclkx) depending on the audio being played.

Hi Dwarakesh R

By applying with below code and remove system-clock-frequency = <24576000>; under &mcasp5 we can measure AHCLK but the freq is still wrong.

sound0_master: simple-audio-card,cpu {
sound-dai = <&mcasp5>;
system-clock-frequency = <24576000>;

system-clock-direction-out;

};

aplay -Dplughw:0,0 sample06.wav

ACLKX frequency is 3.125MHz

FSX frequency is 96KHz

AHCLK frequency 50MHz

aplay -Dplughw:0,0 test.mp3

ACLKX frequency is 0.52MHz

FSX frequency is 16KHz

AHCLK frequency 16.65MHz

Regards,

Scott

Hi Scott,

Can you confirm in the above logs OSC1 is not 25MHz and as expected before 24.576MHz ? Can you please share your latest device tree changes regarding audio ?

Also can you please take a dump of the following registers, when audio is played and if possible when being played. Please enter these commands in linux command shell

# devmem2 0x4A009878

# devmem2 0x48470014

# devmem2 0x48470018

# devmem2 0x4847001c

# devmem2 0x48470020

# devmem2 0x484700B0

Hi Dwarakesh R.

=> Can you confirm in the above logs OSC1 is not 25MHz and as expected before 24.576MHz ? Yes and clockout2 has no freq due to previous change

Hi Scott,

I have recent PRSDK 6.3 and the clock naming conventions have changed.

Can you please share your arch/arm/boot/dts/dra7xx-clocks.dtsi and arch/arm/boot/dts/dra7.dtsi files from your source code ?

Hi Scott,

Few suggestions. In dra7xx-clocks.dtsi, can you please change the following entries made dark. Please do measure the frequencies and also dump the registers as done like before.

sys_clkin2: sys_clkin2 {
#clock-cells = <0>;
compatible = "fixed-clock";
clock-frequency = <24576000>;
};

dpll_abe_ck: dpll_abe_ck@1e0 {
#clock-cells = <0>;
compatible = "ti,omap4-dpll-m4xen-clock";
clocks = <&abe_dpll_clk_mux>, <&abe_dpll_bypass_clk_mux>;
reg = <0x01e0>, <0x01e4>, <0x01ec>, <0x01e8>;
assigned-clocks = <&dpll_abe_ck>;
assigned-clock-rates = <24576000>;
};

Hi Scott,

Is there a typo in AHCLKX in the tests above between sample06.wav(30.2MHz) and test.mp3(10MHz) ?

Though I believe you have this entry:

assigned-clocks = <&abe_dpll_sys_clk_mux>;
assigned-clock-parents = <&sys_clkin2>;

Read at address 0x4A0051EC (0xb6f7c1ec): 0x00802B22

abe_dpll_sys_clk_mux mux is still coming at the time of configuration from sys_clkin1 instead of sys_clkin2. Though actually by probing it comes from sys_clkin2

24.576MHz = 20MHz * 43(2B) / 35 (22)

But actually the clock is 24.576 and so above calculation becomes

24.576 * 43 / 35 = 30.2 MHz

I have 2 suggestions in dra7xx-clocks.dtsi. Please pick either of these and not both together. When trying one, revert the other one back to the previous state.

Option 1:

Option 2:

abe_dpll_sys_clk_mux: abe_dpll_sys_clk_mux@118 {
#clock-cells = <0>;
compatible = "ti,mux-clock";
clocks = <&sys_clkin2>;
reg = <0x0118>;
};

You can perform either of these two options at a time. When trying the other option(option2), please revert back option1 and vice versa.

Hi Dwarakesh R.

=> Is there a typo in AHCLKX in the tests above between sample06.wav(30.2MHz) and test.mp3(10MHz) ?

Yes, AHCLKX should be 30.2MHz when playing sample06.wav

For Option 1:

while playing test.mp3 the frequency are

ACLKX = 0.256MHz

FSX = 8KHz

AHCLK = 8.19MHz

Clockout2 = null

while playing sample06.wav the frequency are

ACLKX = 1.535MHz

FSX = 48KHz

AHCLK = 24.576MHz

Clockout2 = null

For option 2

Kernel crash dmesg attached audio_option2.rar

Hi Scott,

The frequencies appear to match. Do you hear the audio now ? Looks like there is only 16-bit.24-bit and 32-bit supported by AKM4432

8KHz * 16 bits * 2 channels = 256 KHz bitclock

8KHz = Frame Clock FSX

Are you able to hear audio in either of the options ? Atleast 48KHz should play it matches 512fs of Codec requirement.

Hi Dwarakesh R.

under option 1

For aplay -Dplughw:0,0 test.mp3 [Unsigned 8 bit, Rate 8000 Hz, Mono] No, we still can NOT hear anything. should we change the source file?

For aplay -Dplughw:0,0 sample06.wav [Signed 16 bit Little Endian, Rate 48000 Hz, Mono] Yes, we can hear sound clearly.

I tried to change another file but still can NOT hear anything

aplay -Dplughw:0,0 a2002011001-e02-8kHz.wav [Signed 16 bit Little Endian, Rate 8000 Hz, Stereo]

under option 2

kernel crash it can not play anything

Regards,

Scott

0 Dwarakesh Radhakrishnan over 3 years ago in reply to Scott Lin2

Hi Scott,

Looks like 8.192MHz is 1024fs where fs is 8Khz. This is not supported in AKM4432.

One quick change which you can try to confirm is, while audio is being played for 8KHz, can you change the below on the fly. If the command gets executed, then you try probing and seeing if the clock AHCLKX changes from 8.192MHz to 4.096MHz and audio plays properly

# devmem 0x484700B4 w 0x00008005

After confirming above, if it is possible and working you can try something below, not sure if it will address it:

Try one of these each time : clocks = <&mcasp5_aux_gfclk_mux>; or clocks = <&dpll_abe_ck>; or clock = <&dpll_abe_m2_ck>

sound0: sound@0 {
compatible = "simple-audio-card";
simple-audio-card,name = "DRA7xx-EVM";

simple-audio-card,mclk-fs = <512>;

simple-audio-card,widgets =
"Headphone", "Headphone Jack",
"Line", "Line Out",
"Microphone", "Mic Jack",
"Line", "Line In";
simple-audio-card,routing =
"Headphone Jack", "DAC to AOUT";
simple-audio-card,format = "i2s";
simple-audio-card,bitclock-master = <&sound0_master>;
simple-audio-card,frame-master = <&sound0_master>;
simple-audio-card,bitclock-inversion;

sound0_master: simple-audio-card,cpu {
sound-dai = <&mcasp5>;
clocks = <&mcasp5_aux_gfclk_mux>; or clocks = <&dpll_abe_ck>; or clock = <&dpll_abe_m2_ck>

system-clock-direction-out;
};

simple-audio-card,codec {
sound-dai = <&audio>;
};
};

audio: audio-codec@19 {
#sound-dai-cells = <0>;
compatible = "akm,ak4432";
reg = <0x19>;
};

&mcasp5 {
#sound-dai-cells = <0>;
assigned-clocks = <&abe_dpll_sys_clk_mux>, <&dpll_abe_ck>;
assigned-clock-parents = <&sys_clkin2>;

assigned-clock-rates = <0>, <24576000>;

status = "okay";

op-mode = <0>; /* MCASP_IIS_MODE */
tdm-slots = <2>;
/* 4 serializers */
serial-dir = < /* 0: INACTIVE, 1: TX, 2: RX */
1 0 0 0

tx-num-evt = <32>;
rx-num-evt = <32>;
};

Forgot to mention, you need to change on the fly below also

# devmem2 0x484700B0 w 0x1F

along with

# devmem 0x484700B4 w 0x00008005

after issue the command devmem 0x484700B4 w 0x00008005 & devmem2 0x484700B0 w 0x1F

the frequency all changed and stil NO sound

ACLKX = 0.128MHz

FSX = null

AHCLK = 4.096MHz

Clockout2 = null

Hi Scott,

Cleaner way is the device tree changes mentioned above. Before that as you did above, please repeat with the below command also

Forgot to mention, you need to change on the fly below also

# devmem2 0x484700B0 w 0x1F

along with

# devmem 0x484700B4 w 0x00008005

Hi Dwarakesh R.

OK, I will try to modify DTS and test with these two command on the fly. back to you soon~

Regards,

Scott

Hi Scott,

I see you have given both the commands on the fly. But clock should have measured 8KHz instead of 4KHz

Hi Dwarakesh R.

=> Try one of these each time : clocks = <&mcasp5_aux_gfclk_mux>; or clocks = <&dpll_abe_ck>; or clock = <&dpll_abe_m2_ck>

I would name test 1, test 2 and test 3 with out issue command devmem 0x484700B4 w 0x00008005 & devmem2 0x484700B0 w 0x1F

For test 1, test 2 & test 3

the frequency is always the same with two file sample06.wav and test.mp3

ACLKX = 1.535MHz

FSX = 48KHz

AHCLK = 24.576MHz

Clockout2 = null

If I boot up DUT and play sample06.wav it sounds normal and good, but once I played test.mp3 (8KHz fileand sounds like noise) then go back to play sample06.wav again. the speed becomes un-normal it becomes faster and the first time.

If I issue the command on the fly, the FSX will be gone and of course no sound.

Regards,

Scott
