TAS5805MEVM: Need your support to bringup TAS5805MPWPR codec with IMX8MM with Android 11 code

Hi Divyesh

1. yes, android version doesn't affect by amplifier.

2.if IMX8MM has i2c and i2s port, it canbe used.

3.yes, you can

4.we don't have special driver codec. you can send command by i2c directly.

5. you can go to this page for the PPC3 software to control the EVM board.

https://www.ti.com/tool/TAS5805MEVM?keyMatch=&tisearch=search-everything&usecase=partmatches

thanks.

Jesse

4. then how we can integrate it with IMX8MM processor. We need driver file to control audio codec? 

5. Software guide to integrate with Android code base. 

Hi

I am sorry that TI don't have the driver file or code to support this.

Jesse

In our design we are having this IC with custom board  IMX8MM with Android 11 code base.

We have to give support for this.. If you don't have codec driver file.. so how it will work?

Hi

we can provide the register position and the description for each register.

I think if you can ask IMX8MM to provide the support for the port writing and reading.

thanks

Jesse

Yes please...

All register related description was written in file of blow link.

https://www.ti.com/lit/an/sloa263a/sloa263a.pdf?ts=1653354057221&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FTAS5805MEVM

Please check below link:

tas5805m.c - sound/soc/codecs/tas5805m.c - Linux source code (v5.18) - Bootlin

Is this a updated driver?

The register seems no problem.

I think you can take a try.

thanks.

Jesse

Hi Jesse,

Looks like initial register map is not initialized in driver code. Attaching referance.

.0654.stereo_flow2_48kHz_default_coldboot_-10dB.h

Header file is not there. Do I need to add anything in header file?

Please check driver file. if anything is missing, please let me know.

Thanks

Divyesh

anything else need to be changed ? to make this codec works? apart from kernel changes

We are using Android 11 Code base.

I am sorry that we don't have any android code for the device.

thanks.

Hi Jesse,

I have two options for driver file -

1. Use this driver file : tas5805m.c - sound/soc/codecs/tas5805m.c - Linux source code (v5.18.2) - Bootlin

If we are using this driver , then can you please provide  "tas5805m_dsp_%s.bin" firmware file.

2. Or  shall I go for below driver and header file

 6082.stereo_flow2_48kHz_default_coldboot_-10dB.h

Need your help to choose only one, which will help in Kernel 5.10 version and android 11 code base 

thanks

Divyesh

Divyesh

please refer below link. 

these code is the only thing what we can provide.

i am not sure does it work for you. Please confirm.

https://tidrive.ext.ti.com/u/sig85JwoPO6gKDzo/1197b1ae-593a-42f8-85bc-d2eb884fd2e3?l

we don't have any bin file to provide.

so maybe you need to use .h file or you can confirm does the file in the link work for you or not.

thanks.

Jesse

Hi Jesse,

Need your help to initialize DTS file.

I cant see any pins driver file to control from dts. like fault, pdn pin.

If you check our schematic, We need to control below few pins which highlighted in yellow.

help to control this pins from imx.

pls confirm

Hi Divyesh

we don't have that kind of file.

you mean you use your mcu pin to control our pin of IC, i think this file should provide by MCU company.

thanks.

Jesse

The driver file you suggested, doesn't have pins to control fault, pdn pins.... 

how to configure these pins then?

those are all files we can provide.

please confirm imx8mm how it send the signal.

Pdn, fualt pins will be connected to IMX8MM..

When codec need to powerdown..imx can send signal on this pins...

these pins will be configured in dts files....and dts node for this codec will be parsed in driver... so driver should control this pin.

ThankS

Hi Team,

I'm configuring I2S signals for TAS5805M. As per the datasheet MCLK is not required.

Could you please brief on BCLK and WCLK clocks... How these clocks will be generated. 

What are the value we are expecting at BCLK and WCLK?

Thanks

Hi Divyesh

you can use mclk as bclk, which is the sclk of amp.

the wclk is the LRCLK of amp.

about the value, you can refer the below table.

Hi Divyesh

for the question is a different one, can we change the thread to different e2e ticket, or you can contact me by e-mail.

my e-mail address is : jesse-ji@ti.com

thanks.

Jesse

Hi Jesse,

Thanks for the data and Mail-ID.

Added driver file shared by you [https://tidrive.ext.ti.com/u/sig85JwoPO6gKDzo/1197b1ae-593a-42f8-85bc-d2eb884fd2e3?l] and done with DTSI and all other required changes. but we are facing compilation issue as API's used in driver file are from older kernel version. This driver file is having less features , even sound controls are not there.

I was planning to go with tas5805m.c - sound/soc/codecs/tas5805m.c - Linux source code (v5.18) - Bootlin driver. This driver looks good ( not facing any compilation issues ). BUT, this driver requires bin file for DSP configuration. Could you please help for that ?

Thanks

Divyesh

Hi Divyesh

i am afraid that our side don't have that kind of bin file.

thanks.

Jesse

bin file is nothing but DSP config header file ... I am going to use header file change instead of bin ..

Will share changes . I want you to review it properly.

thanks

I have made few changes in code to load header file which is having DSP configuration setup array.

I want expert advice on that changes, Could you please review these changes once. Since DSP configuration is most imp part of it.

Hi 

   Our whole team is focused on the audio amp devices. This IMX8MM device is not TI's products, I'm afraid no one here is familiar with it. No one understand the codes you post, I'm afraid.

I have made changes for TAS5805M to support with IMX8MM processor.

I wanted you to review above patch file , which is having header file changes for DSP config

I'm afraid no one here is familiar with it. No one understand the codes you post, I'm afraid.

Hi Shadow,

Used drive file:  tas5805m.c - sound/soc/codecs/tas5805m.c - Linux source code (v5.18) - Bootlin

File path is correct : vendor/firmware

Driver was trying to look firmware file before file system mount on device. That’s why it was throwing an error as file not present.

After few changes able load it properly and codec got registered.

Hi Divyesh

   Seems problem solved. Glad to heat that.

Still audio codec interface need to be up.!

Hi Shadow He ,

We are using TAS5805MEVM board. We are going to connect with IMX8MM.

We want to give external I2S and i2C signal to the TAS5805MEVM board.

IMX8MM <<---->> BCLK,WCLK,DIN,DOUT <<--->> TAS5805MEVM board

Need to isolate i2S signal from SPDIF and XMOS.

What are the pin settings need to be done for that.

What i2c signal I have to use.. We are giving i2c from IMX8mm processor

IMX8MM <<---->> i2c <<--->> TAS5805MEVM board

Design:

Hi Divyesh

   You can use J12 J13 J14 to send in I2S, use J18 and J19 to send in I2C. This EVM can't completely isolate signal path from XMOS or SPDIF physically, but if you don't use PPC3 software to control, only power up the EVM. There should be no I2S and I2C signal from XMOS or SPDIF.

Thanks Shadow He,

Will try these configurations..

1. To power up the board, Do we need external power supply or we need to connect USB?

2. What should I set I2C address in dts file. 

3. After powering up, if we are not using PPC tool then XMOS and SPDIF should not work as per your inputs right?

Thanks

Divyesh

Hi Divyesh

1. To power up the board, Do we need external power supply or we need to connect USB?

Both is necessary. power supply provide the power for PVDD, usb provide the power for DVDD.

or you can use an external power supply to provide the power for DVDD, then the USB should be unnecessary.

2. What should I set I2C address in dts file. 

if u use the upper side chip, it is 0x58

the down side chip is 0x5a

3. After powering up, if we are not using PPC tool then XMOS and SPDIF should not work as per your inputs right?

XMOS should not work anymore, but you can switch the input to SPDIF on the board, it should work i think.

thanks.

Jesse

Hi Jesse Ji,

Thanks for the inputs.

Jesse - XMOS should not work anymore, but you can switch the input to SPDIF on the board, it should work i think.

Divyesh - Ok got it. In our case we are not using XMOS and SPDIF, We want to I2S and I2C signals from IMX8mm Processor directly. We are not using any PPC tool for any configuration.

Hi Jesse,

To give external I2S signal from IMX8MM, What should I keep jumper settings in below image:

Confused between BYPASS and PSIA. Please clear out the doubt.

Divyesh

if you use the external i2s, you can just remove the jumper.

thanks.

Jesse

Hi Jesse Ji,

Could you please share DSP settings header file for BTL (non-PBTL configuration). As per out design, We should go for BTL configurations register settings.

I know that using a non-PBTL configuration on PBTL hardware will trip the short-circuit protection, but I'm not sure if this will occur the other way around -- perhaps it will be fine?

Hi Divyesh

You can using the PPC3 tool to generate the head file for amplifier setting.

the setting is not decide by TI, it should decide by your hardware engineer.

thanks.

Jesse

Hi Jesse ji,

We don't have provision to connect audio codec with Laptop. Could you please here to generate header file for PBTL and BTL configuration?

Question on Power control: 

Is it possible to control the output power for this IC?

AS per our requirement, We have two TAS5805M IC's in design. These IC's has their specific use cases.

Audio Internal Amplifier 0.8W Speaker - TAS5805M - This IC will be specifically use for 0.8W power (PBTL configuration)-

Use case for this IC - This Amp will be used for notification and Alarm ringtone

2X20W AUDIO AMPLIFIER - TAS5805M- This IC will be specifically use for 2*20W power (BTL configuration).

Use case for this IC - This Amp will be used for media player or we can say as a woofer we are using it.

To achieve above requirement, What changes need to done so that we can achieve respective power from the output?

This is major requirement we have in our design. Please share inputs to achieve above requirement.

Hi @luis,  

We have integrated TAS5805M EVK with IMX8MM.

Please check Image below:

We have connected USB for DVDD. We are giving PVDD - 21 V. External I2S and i2C we are giving

I2S lines soldered at bottom side:

After integrating all the changes, We are facing one issues.

Need you help to check the issues.

Thanks

Divyesh.

Hi Divyesh

can you confirm the waveform of i2s and i2c? Also the pvdd and dvdd voltage.

Also which chip are you using? it seems like you are using Amplifier U1.

Am i understanding right?

thanks.

Jesse

No I2S waveform coming out.

I2C is working. Able to dump and detect.

U1 we are using

Pvdd is 21v and dvdd 3.3v
