connected to any device or decoder)

Make sure you have configure McASP as master.

Do you use TI SDK? If yes, which exactly?

What changes you have made to the default McASP driver?

Regards,
Pavel

Hi Botev,

Thanks your reply.
I use TI SDK is " glsdk_7_04_00_03". The part of McASP driver has not been modified.
Could you tell me how to configure McASP as master? Which file should I modify?

Shawn,

Actually McASP is set as master by default in GLSDK 7.04.00.03. See the below files:

linux-kernel/sound/soc/davinci-evm.c -> dra7xx_evm_link -> SND_SOC_DAIFMT_CBS_CFS

linux-kernel/sound/soc/davinci-mcasp.c

case SND_SOC_DAIFMT_CBS_CFS:

/* codec is clock and frame slave */

 

As you do not have external audio chip and if you do not have plans to add in the future, you can disable the McASP support (which is enabled by default), follow the below wiki:

processors.wiki.ti.com/index.php/Linux_Core_Audio_User's_GuideN#DRA7_and_DRA72_EVM

Otherwise you should replace the TLV320AIC3x codec with dummy codec. See the below wikis for more info:

This page presents a step by step guide for interfacing an audio DAC to the McASP.

You don't actually need to have the PCM5102a board to follow this guide; the drivers that will be created will work just fine without it connected. You can even use an o-scope to probe the audio data lines and clocks to see that the driver is working.

Note also that TLV320AIC3x codec is using I2C1 and pin B26 (XREF_CLK2) as MCLK. You might remove that also.

Regards,
Pavel

Shawn,

You have stated in your previous posts:

" trying to port MCASP driver on our test board (This MCASP interface is not connected to any device or decoder). but now it can not boot anymore"

"The part of McASP driver has not been modified"

Could you please specify what changes exactly you have made so far regarding McASP? From what I understand before these changes, you were able to boot, correct? Could you please provide boot log of your successful boot (before McASP changes)?

Regards,
Pavel

Hi Botev,

I need to set the McASP3 to "burst mode", and connect McASP3 interface of two J6 module to each other(Master and Slave, no external audio chip) for data transmission.

The boot is successful before enable McASP on our test board, because I disable the McASP, as follows,
arch/arm/mach-omap2/omap_hwmod_7xx_data.c
static struct omap_hwmod_ocp_if *dra7xx_hwmod_ocp_ifs[] __initdata = {
// &dra7xx_l4_per2__mcasp2,
// &dra7xx_l4_per2__mcasp3,
// &dra7xx_l4_per2__mcasp6,
// &dra7xx_l4_per2__mcasp7,
// &dra7xx_l4_per2__mcasp8,

the successful boot log as follows,

Yes, it's J6 McASP3 master board.

When I disable the unused McASP configuration, It can boot normally now.
But it still occur the following error log, it seems to be associated with mcasp3 clock.
How should I setup to fix it?
thanks.

omap_hwmod: mcasp3: cannot be enabled for reset (3)

Check you DTS files. See the below e2e thread for more info:

Regards,
Pavel

My toolchain is "gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux"

I refer to that link, and disable other McASP(1,2,4,5...), only enable McASP3, it appear the same message, but boot is successful before I disable McASP3 in "omap_hwmod_7xx_data.c".

could you tell me, about "clock: dpll_abe_ck failed transition to 'locked'","omap_hwmod: mcasp3: cannot be enabled for reset (3)" which part needs to be modified in these DTS files? is clock?

If I want to set McASP3 as master, should I change the ".master" to & dra7xx_mcasp3_hwmod?
/* l4_per2 -> mcasp3 */
static struct omap_hwmod_ocp_if dra7xx_l4_per2__mcasp3 = {
.master = &dra7xx_l4_per2_hwmod,
.slave = &dra7xx_mcasp3_hwmod,

or, if I don't use DTS, and make a new driver to set McASP3 to master mode, should I need to enable the PRCM before read/write corresponding memory address of McASP? How do I enable PRCM??

If I don't use DTS, and make a new driver to set McASP3 to master mode, should I need to enable the PRCM before read/write corresponding memory address of McASP? How do I enable PRCM??

Hi Shawn,

You can download and install DRA75x Clock Tree Tool, or you can search chapter 3 in the TRM for anything related to MCASP.

There is not so much to touch and enable MCASP.

Regards,

Stan

Hi, Shawn,

Recently, DRA75x CTT has been added to CLOCKTREETOOL-AUTOMOTIVE bundle package:

You should install it to use DRA75x CTT.

Regards,

Mariya

Thanks for your reply,
could you tell me, about log"clock: dpll_abe_ck failed transition to 'locked'" and "omap_hwmod: mcasp3: cannot be enabled for reset (3)" which part I needs to be modified in these DTS files?
is "fck_parent" of mcasp3 in dra7-evm.dts? "clocks = <&mcasp3_ahclkx_mux>" in dra7.dtsi?

Hi Shawn,

Could you please provide me your DTS files for review? Which McAPS3 master board pins you are using? DRA75x EVM use pin B26 (mode atl_clk2) to supply clock to TLV320AIC3106 MCLK. Do you use this pin B26 in your custom master board?

Please provide me also the values you have in the below registers in master board, take these with devmem2 tool from user space.

CM_L4PER2_MCASP3_CLKCTRL

CTRL_CORE_PAD_MCASP3_ACLKX
CTRL_CORE_PAD_MCASP3_FSX
CTRL_CORE_PAD_MCASP3_AXR0
CTRL_CORE_PAD_MCASP3_AXR1
CTRL_CORE_PAD_XREF_CLK2

Have you made any changes in Platform driver (sound/soc/davinci/davinci-mcasp.c) and/or Machine driver (sound/soc/davinci/davinci-evm.c)? If yes, please send me the updated file for review.

See also if the below appl note will be in help:
www.ti.com/.../sprac09a.pdf

Regards,
Pavel

Hi,

This PIN B26 is not connected to another device, it's open now.
{ MCASP3_ACLKX, (M0 | PIN_OUTPUT) }, /* mcasp3_aclkx.mcasp3_aclkx */
{ MCASP3_FSX, (M0 | PIN_OUTPUT) }, /* mcasp3_fsx.mcasp3_fsx */
{ MCASP3_AXR0, (M0 | PIN_OUTPUT) }, /* mcasp3_axr0.mcasp3_axr0 */
{ MCASP3_AXR1, (M0 | PIN_OUTPUT) }, /* mcasp3_axr1.mcasp3_axr1 */

The attachment is a my current DTS, driver files and my boot log.

in "Boot log_1.txt"
this is the current boot log, it can not boot properly.

in "Boot log_2.txt"
for using devmem2 tool and boot properly, I modify the function "davinci_mcasp_probe"(davinci-mcasp.c), as follows
/*
mcasp_reparent_fck(pdev);

printk("\n==============================> [davinci_mcasp_probe] Test <==\n");

if (mcasp->version == MCASP_VERSION_4) {
pm_runtime_get_sync(mcasp->dev);
mcasp->revision = mcasp_get_reg(mcasp, DAVINCI_MCASP_PID_REG) &
MCASP_V4_REVISION_MASK;
pm_runtime_put(mcasp->dev);
}
*/

and I got these memory value,

If I want to set McASP3 as master, should I change the ".master" to & dra7xx_mcasp3_hwmod?
/* l4_per2 -> mcasp3 */
static struct omap_hwmod_ocp_if dra7xx_l4_per2__mcasp3 = {
.master = &dra7xx_l4_per2_hwmod,
.slave = &dra7xx_mcasp3_hwmod,

No, you should not. No changes regarding mcasp3 in omap_hwmod_7xx_data.c file are needed.

or, if I don't use DTS, and make a new driver to set McASP3 to master mode, should I need to enable the PRCM before read/write corresponding memory address of McASP? How do I enable PRCM??

You should use DTS, you can not transfer McASP DTS settings to McASP driver. The McASP3 is enabled/disabled in PRCM from the McASP driver.

This PIN B26 is not connected to another device, it's open now.

You should remove this pin usage and also AIC3106 usage from your dra7-evm.dts file. I though you get my point regarding aic3106 replacement with dummy codec (from the below e2e post), but I see this is not the case.

You should update your dra7-evm.dts and davinci-evm.c files (replace AIC3x with dummy).

{ MCASP3_AXR1, (M0 | PIN_OUTPUT) }, /* mcasp3_axr1.mcasp3_axr1 */

This pin set as input (AIC3x DOUT) by default. If you set it as an output, you can not use audio record/capture.

this is the current boot log, it can not boot properly.

Seems like DPLL_ABE can not lock by some reason. have you made any changes regarding DPLL_ABE settings?

These values looks strange. What physical addresses you are using for these registers?

I'm sorry about that, udated it as follow,

Thanks for reply.
I checked hardware layout of the my test board and found that my test board's clock source was slightly
different from the EVM(as attachment)
Is this the cause of "clock: dpll_abe_ck failed transition to 'locked'"?
If I want to adjust the clock to match my hardware layout, how to set it?
or, for clock, do I have to configure the same hardware layout as the EVM?

HW_Clock.7z

After I modify as fllows,

in"clk-7xx.c"

// sys_clkin2 = clk_get_sys(NULL, "sys_clkin2"); //Original
sys_clkin2 = clk_get_sys(NULL, "sys_clkin1");

I can boot success now. 

Is this a reasonable change for our hardware design?

In addition, DPLL_ABE can be sourced from sys_clkin1 (OSC0) or sys_clkin2 (OSC1), this is selected from CM_CLKSEL_ABE_PLL_SYS[0] CLKSEL

If you decide to stay with sys_clkin1 (OSC0), I would suggest to align you code like below:

// sys_clkin2 = clk_get_sys(NULL, "sys_clkin2"); //Original
sys_clkin1 = clk_get_sys(NULL, "sys_clkin1");
