DRA71XEVM: Unable to detect Deserializer as i2c slave

Hi Prasad,

Which i2c instances is the Deserializer connected to?
Have you checked the pin muxing is done right for that particular i2c instance?

- Keerthy

Hello Keerthy,

Thanks for the prompt reply.

We have connected the  board on our Dra71x EVM on i2c5 instance.

With respect to pinmuxing we have'nt modified anything. 

Request you to let us know what king of modifications we need to do for detect this Deserializer EVM board.

Hi,

In your u-boot:

File: board/ti/dra7xx/mux_data.h

{MCASP1_AXR0, (M10 | PIN_INPUT_SLEW)}, /* mcasp1_axr0.i2c5_sda */
{MCASP1_AXR1, (M10 | PIN_INPUT_SLEW)}, /* mcasp1_axr1.i2c5_scl */

This should take care of pin muxing.

Can you try:

i2cdump -f -y 0x4 deseralizer_Slave_ID?

Also can you share the output of i2cdetect?

- Keerthy

Hello Keerthy,

Pls find the output of the commands your asked to execute below

root@dra7xx-evm:~# i2cdump -f -y 0x4 0x30
No size specified (using byte-data access)
Error: Could not open file `/dev/i2c-4' or `/dev/i2c/4': No such file or directory

root@dra7xx-evm:~# i2cdetect -y 5
Error: Could not open file `/dev/i2c-5' or `/dev/i2c/5': No such file or directory
root@dra7xx-evm:~#

Note: We have loaded the pre-existing images into the EVM to execute above commands, hope the code you have mentioned would be part of those pre-existing images.

Hi Prasad,

Seems like devices are not registered for some reason. Can you share your complete boot logs?
From SPL to prompt? that will help me analyze.

Best Regards,
Keerthy

Hello Keerthy,

&i2c5{
status = "okay";
clock-frequency = <400000>;

};

With above code, i could able to detect a new i2c bus as i2c-4 in the /dev as below

But getting these timeout errors.

From google what i found is could be bcz of the pull ups on the pinmux.

So we have added below piece of code in dra7-evm.dts file, but we gets the same error.

mcasp1_axr0_pin: pinmux_mcasp1_axr0_pin {
pinctrl-single,pins = <
/* this pin is used as a i2c SDA via mcasp */
DRA7XX_CORE_IOPAD(0x36b4, PIN_INPUT_PULLUP | MUX_MODE10)
>;
};

mcasp1_axr1_pin: pinmux_mcasp1_axr1_pin {
pinctrl-single,pins = <
/* this pin is used as a i2c SCL via mcasp */
DRA7XX_CORE_IOPAD(0x36b8, PIN_INPUT_PULLUP | MUX_MODE10)
>;
};

Can you pls correct me if the above code is fine to fix the pinmux issue?

Also, As you mentioned in your previous reply, 

{MCASP1_AXR0, (M10 | PIN_INPUT_SLEW)}, /* mcasp1_axr0.i2c5_sda */
{MCASP1_AXR1, (M10 | PIN_INPUT_SLEW)}, /* mcasp1_axr1.i2c5_scl */

But above code is for dra72 it seems, for dra71 below is the code

{MCASP1_AXR0, (M10 | PIN_INPUT_PULLUP | SLEWCONTROL)}, /* mcasp1_axr0.i2c5_sda */
{MCASP1_AXR1, (M10 | PIN_INPUT_PULLUP | SLEWCONTROL)}, /* mcasp1_axr1.i2c5_scl */

Correct me if my understanding is wrong

Hi Prasad,

You are right. That is for dra71.

Could you please share the values of the below registers using devmem2:

devmem2 0x4A0036B4 w
devmem2 0x4A0036B8 w

That will be double to check to see if the settings are fine. Also you previous post there is a picture that you have attached but it is not visible.
Please attach the full logs as a text file.

Hello Keerthy,

Thanks for the reply.

Instead of Dra71x we are using TDA2e/Dra72x board to connect our deserializer board.

Considering Datasheet and TRM of TDA2e/Dra72x, we have done the below settings.

des_i2c_pins:pinmux_des_i2c_pins {
pinctrl-single,pins = <
DRA7XX_CORE_IOPAD(0x36b4, MUX_MODE10 | PIN_INPUT) /* this pin is used as a i2c5 SDA via mcasp */
DRA7XX_CORE_IOPAD(0x36b8, MUX_MODE10 | PIN_INPUT) /* this pin is used as a i2c5 SCL via mcasp */
>;

&i2c5{
status = "okay";
clock-frequency = <400000>;
pinctrl-names = "default";
pinctrl-0 = <&des_i2c_pins>;

ti9x4@30 {
compatible = "ti,ti9x4";
reg = <0x30>;
};
};

after loading the images with above code compiled, we see the below log from root of the target

We have connected our deserializer board on i2c5, as we have aliasing on .dts file, we are expecting our slave to appear on i2c4 of /dev/i2c-4 on the target, but we are not getting this recognized.

Pls help us if we need to modify any any other code for this?

Hi Prasad,

Again a full boot log will help me analyze the ordering of i2c instances.

Keerthy

Hello Keerthy,

We realized that, the board we were tested was not the correct one to be tested and when we tested on a correct one we achieved what we need.

Hence i request you to close this thread.

Many thanks for your help.
