RT5639 on TX2

ShaneCCC · August 2, 2017, 7:21am

Do you mean the p2180? Yes there’s no different.

Tonie · August 2, 2017, 7:27am

The EVB I had is P2597

ShaneCCC · August 2, 2017, 7:36am

@Tonie
It’s my mistake it’s P2597. P2180 is TX1 module.

Tonie · August 2, 2017, 7:59am

Hi, ShaneCCC,

I put TX2 module on P2597, all I2C looks fine.
(For example, I used ‘i2cdetect -r -y 0’ and it shows something. (No any error be shown)
It really confused me because I didn’t use other OS on that. (TX2 module has OS installed)

I would like to know if there is any ‘board id’ that OS will detect ?

Please advise.

Regards,

Tonie

Hi, ShaneCCC,

here are the testing result I had :

My Carrier board + TX2 module (same OS) : failed in accessing all I2C.
My Carrier board + TX1 module : success in accessing all I2Cs.
P2597 carrier board + TX2 module (same OS) : success in accessing I2Cs.

Compare the log between item 1 and 3, I list some :

node /plugin-manager/fragment-e3326@0 match with board 3326-*
This line only be shown in P2597
GPIO line 461 (cam0-rst) hogged as output/high
This line only be shown in my carrier board.

Please advise.

Regards,

Tonie

@Tonie
Could you confirm all the i2c failed on your carrier board? Could you check with your HW developer all of the i2c device and check all of them are failed, not just use the i2c-tools to tell all of them are failed, because some of device need power on by the device driver then can access it.

Tonie · August 3, 2017, 5:05am

ShaneCCC,

I would like to know if there is no device located on the path of any I2C, does it have problem in ‘i2cdetect’ ?

As we know, even P2597, some I2C has no device be located on its path.
And it doesn’t shown any fail if I use ‘i2cdetect’ command.

I don’t understand why the same OS shows ‘no ack’ on my carrier board even it has no device be located on its path.

P.S.: I tested all I2Cs via i2cdetect but fail.

Regards,

Tonie

ShaneCCC · August 3, 2017, 5:39am

“no ack” means host send identify command to devices and devices have no response. Please define what you mean have problem in i2cdetect?

Tonie · August 3, 2017, 5:42am

Hi, ShaneCCC,

Similar error messages like :

ShaneCCC · August 3, 2017, 5:52am

As I said this message tell the 0x4,0x5 … slave device have no response doesn’t mean all i2c bus not working. You should get the same message form the P2597 too.

Tonie · August 3, 2017, 6:14am

Hi, ShaneCCC,

I feel apology that I make a big mistake.
I gave you wrong information because the result of using ‘i2ctools’ are different between uses terminal on desktop and console. It confuses me.

Let me re-report the current status :

TX2 on my carrier board :
i2c@C240000 is working but the waveform is wrong.
The pulse from oscilloscopeare wrong.
Each pulse is far from the other one.
TX1 on my carreir board :
i2c is working and the waveform is correct.

Am I set wrong speed ?
In tegra186-soc-i2c.dtsi, the clock frequency of the gen2_i2c is 100000.
Which one is correct ?

Please advise.

Regards,

Tonie

Trumany · August 3, 2017, 6:47am

Did you measure the frequency of them? Can you please post waveform picture here?

Tonie · August 3, 2017, 8:08am

Hi, Trumany,

I cannot post image here. Could you please tell me how ?

I measure the time different between each pulse, it is around 7 ms.
It’s too big to be read/write by rt5639. That’s the reason my system always show ‘no ack’.

I also tried to set clock-frequency to be 400000 but it is still fail.

No idea of why.
May I have your advise for further step ?

Regards,

Tonie

@Tonie
You just need to click the Image button in the toolbar and choose the picture to upload.

External Media

Tonie · August 3, 2017, 9:07am

When I click that, it shows

ShaneCCC · August 3, 2017, 9:26am

@Tonie
Have no idea why you can attached image here. Please upload the image somewhere else and provide the link here.

AlexHou · August 4, 2017, 1:55am

Tonie cannot upload the img. So I’m helping him to upload here:
[url]https://upload.cc/i/Fq60TZ.bmp[/url]

From the waveform, device is not ‘ACKing’ to slave address 0x1C.

Tonie,
You need check device side power/reset signal at first.

Tonie · August 4, 2017, 3:48am

Hi, ShaneCCC and Alex,

Now I2C is working for rt5639.
The root cause is ldo1-en pin.

I added :
realtek,ldo1-en-gpios = <&tegra_main_gpio TEGRA_MAIN_GPIO(J,6) GPIO_ACTIVE_HIGH>;
Then the driver is probed successfully.

Now the next issue is

Hi, ShaneCCC,

Now I’ve ported rt5639 related drivers on TX2 and in Settings, you can see rt5639 be shown.
But it has no sound now.

I don’t know if there is other thing I have to set ?

For example, on TX1 , we need to configure I2S via

gpio@6000d000 {
```
 gpio_default: default {
```

     gpio-to-sfio = <8 9 10 11 216 219>;

```
 };
```
};

Is this needed by TX2 ?
Please advise.

Tonie
