DM8168 audio

Emilie Wheatley

Other Parts Discussed in Thread: PMP

Hi,

I'm trying to get the audio working on our DM8168 custom board. Our board is very similiar to the EVM one. It uses AIC3200 codec component, McASP2 to communicate with it and it's controlled by I2C.

Following the instruction in the PSP user manual and the PSP audio driver manual, I changed the driver settings, recompiled the kernel and the audio devices are successfully detected:

asoc: HDMI-DAI-CODEC <-> hdmi-dai mapping ok
asoc: tlv320aic3x-hifi <-> davinci-mcasp.2 mapping ok

**** List of PLAYBACK Devices ****

card 0: EVM [TI81xx EVM], device 0: AIC3X tlv320aic3x-hifi-0 []
Subdevices: 1/1
Subdevices #0: subdevice #0
card 0: EVM [TI81xx EVM], device 1: hdmi HDMI-DAI-CODEC-1 []
Subdevices: 1/1
Subdevices #0: subdevice #0

But when I try arecord or aplay or minimal_capture/minimal_playback example from the EZSDK I get : segmentation fault.

The EVM is using I2C0 but I'm using I2C1. So I'm thinking that might be the problem. But I coudn't find where to change it in the source code.

I tried in board-ti8168.evm, to move:

{
    I2C_BORD_INFO("tlv320aic3x", 0x18)
}

from static struct i2c_board_info __initdata ti816x_i2c_boardinfo0

to from static struct i2c_board_info __initdata ti816x_i2c_boardinfo1

but this time I get "no sound card found"

Either it was a mistake to change the above structure or I need to change/add other line in the driver code?

PLease can you help me with this issue.

I have been also reading the following documentation:

http://processors.wiki.ti.com/index.php/TI81xx_PSP_Porting_Guide#I2C_Driver

but I still can't make sense of this issue.

Regards,

Emilie

    Hi Emilie,

    Which version of the EZSDK you are using? Is it 5.05.02.00? Please provide full boot log from the console output.

    You can check whether you can access (read/write) the I2C1 registers. If not, you should turn on the I2C1 clock from the PRCM registers.

    Other thing is to check if the Media Controller (M3 firmware) is using the I2C1:

    Everything after the "Freeing init memory: 204K" line is quite different. From your initial post, I understood that you have changed only the linux kernel (uImage), nothing else, is that correct?

    From the log, I see you are using MMC/SD card for booting. How do you initially set up your MMC/SD card, are you using the mksdboot.sh script?

    From the log, I see you are not loading the M3 firmware, thus the I2C0 and I2C1 are (by default) not enabled, the clock signals from the PRCM are off. Could you please provide me the value of the CM_ALWON_I2C_1_CLKCTRL register (at physical address 0x48181568).

    Regards,

    Pavel

    Hi Pavel,

    Sorry for the late answer but I was away.

    Indeed I'm booting from SD card.

    the value of CM_ALWON_I2C_1_CLKCTRL is 0x00030000

    Regards,

    Emilie

    Emilie Wheatley said:

    This means I2C1 is disabled (clocks are off). Check DM816x TRM, section 18.7.17.24, to see the CM_ALWON_I2C_1_CLKCTRL register description. You should enable the I2C1 module with writing 0x2 in the CM_ALWON_I2C_1_CLKCTRL[1:0] MODULEMODE bit field;  0x0 - module disabled, 0x2 - module enabled

    Hi

    I'm working with Emilie on this issue and have some more info to add.

    I'm not convinced that the TRM is correct in the bit definitions for the IDLEST field in the CM_ALWON_I2C_n_CLKCTRL registers. I have a working system with both I2C busses enabled (and can access multiple devices on each bus), but when I read these registers, the value 0x00030000 is returned. This would imply that both I2Cs are disabled; which is clearly not the case. I have another system with only I2C0 enabled, but the registers return the status as disabled and I2C1 is enabled. Unless I have made gross errors, then the IDLEST field values are wrong!

    I have a really old Linux build (EZSDK 3.12) for this project which does not have a segmentation fault when arecord is executed. In fact, using this old build I can execute arecord/amixer/aplay and the audio interface works flawlessly (the board has to have a modification though to move the audio codec from I2C1 to I2C0). The seg faults only seem to appear with builds using EZSDK 5.05.

    I hope that info helps in some way.

    Hi Graeme,

    I think the TRM description is correct. When I have the 0x00030000 value in the CM_ALWON_I2C_1_CLKCTRL register, I can not access (read/write) the I2C1 peripheral module registers, which proves that the I2C1 module is not functional. But when I have the value of 0x00000002 in the CM_ALWON_I2C_1_CLKCTRL register, I can successfully access (read/write) the I2C1 peripheral module registers.

    Also, this is what we have in the u-boot source code:

    ti-ezsdk_dm816x-evm_5_05_02_00/board-support/u-boot-2010.06-psp04.04.00.01/board/ti/ti8168/evm.c

    /*****************************************************************
     * Routine: peripheral_enable
     * Description: Enable the clks & power for perifs (TIMER1, UART0,...)
     *
     ******************************************************************/
    static void peripheral_enable(void)
    {

    .....

    /* I2C0 */
        __raw_writel(0x2, CM_ALWON_I2C_0_CLKCTRL);
        while(__raw_readl(CM_ALWON_I2C_0_CLKCTRL) != 0x2);

    .....

    }

    The above is an example of how to enable I2C peripheral module (in this case I2C0, but the same is valid for I2C1).

    BR

    Thanks for the reply.

    I'm sure you are correct, yet I'm reading the values from these registers and they show 0x00030000. And I'm also writing to I2C peripherals without issue! Can it be that i2cset enables the I2C interface, then performs the actions, and finally disables it again.

    But the main issue here is that executing aplay causes a segmentation fault. But only with Linux builds using EZSDK 5.02 onwards.

    How do we trace this seg fault?

    So, are the addresses ok that I use in devmem2?

    I also have LEDs connected to a peripheral on I2C0. They work ok using the command:

    i2cset -y 1 0x44 0x06 0x12 b                                       <--------- 0x44 is the I2C address, 0x06 is theaddressed

                                                                                  register, 0x12 is the reg value.

    and i2cset -y 2 generates a write fail.

    There must be a simple explanation.

    pls use signal(SIGSEGV) and backtrace() to find out the related location.

    Thanks for the suggestion.

    However, not being a Linux programmer, I've no idea how to use that info.

    I've Googled the terms, but that didn't really help me much.

    Can you send me your temp.wav file, I want to test it on my side.

    Thanks for all of your help.

    I can follow what you did and it does the same here.

    I can send you a temp.wav if you want. 15 seconds is about 250MB. Any particular music you like ;)

    The strange thing is, even if the I2C register reads back as 0x00000002 (enabled), after I do an arecord it gets set to 0x00030000 (disabled). But I can still do more arecords. So arecord/aplay and i2cset must enable the I2C as necessary.

    And thanks for the other link too.

    Graeme,

    Let me confirm something.
    The 816X/389X EVM is using I2C0 to control/configure the AIC3106 and McASP2 for audio data transfer with AIC3106. While in your DM816x based custom board you are using I2C1 to control/configure AIC3200, and McASP2 for audio data transfer with AIC3200, is that correct?

    Here is one thread related to I2C driver porting, might be in help:

    Could you please also provide the values of the PINCTRL289 (0x48140C80) and PINCTRL290 (0x48140C84) registers prior executing the "aplay" command.

    Regards,

    Pavel

    Yes, that's correct. We're using the same McASP as the EVM but I2C1 instead of I2C0.

    I looked at those PINCTRL registers earlier. They both read 0x10 which means the pull-up is enabled. The equivalent registers for the I2C0 pins read as 0x18 (pull-up disabled).

    I'll check out your link, thanks.

    Graeme,

    Moving I2C_BORD_INFO("tlv320aic3x", 0x18) from ti816x_i2c_boardinfo0 to ti816x_i2c_boardinfo1 looks like a correct approach for me. Change also the PINCTRL registers from 0x10 to 0x18.

    You should also consider the following:

    I2C1 instance(if count from 0) is used for video capture/display via the daughter cards. The capture/display drivers are developed in M3 side. therefore accessing i2c1 from A8(linux) is not allowed.

    But this issue has been solved since EZSDK 05.03 release. Two different M3 firmware have been provided: dm816x_hdvpss.xem3(having I2C1 control from M3), dm816x_hdvpss_v4l2.xem3(having i2c1 control from A8).

    You can choose the right firmware to load.
