AM5728: LM75 Sensor I2C1 Timeout After SDK 9.03 Upgrade on AM5728 Custom Board

Part Number: AM5728
Other Parts Discussed in Thread: LM75A

Tool/software:

Hello TI Team,

We are in the process of upgrading from TI Linux SDK 6.03 to SDK 9.03 on our custom board based on AM5728. We are facing an issue where the LM75 temperature sensors on I2C1 (i2c@48072000) are not being detected and fail to probe in the kernel.

DTS Snippet:

&i2c2 {
status = "okay";
clock-frequency = <400000>;

proc_temp: lm75@48 {
compatible = "national,lm75a", "lm75";
reg = <0x48>;
interrupt-parent = <&gpio6>;
interrupts = <19 IRQ_TYPE_LEVEL_LOW>;
#thermal-sensor-cells = <1>;
};

handset_temp: lm75@49 {
compatible = "national,lm75a", "lm75";
reg = <0x49>;
interrupt-parent = <&gpio6>;
interrupts = <18 IRQ_TYPE_LEVEL_LOW>;
#thermal-sensor-cells = <0>;
};
};

Kernel Logs:
[ 8.970336] lm75 1-0048: supply vs not found, using dummy regulator
[ 10.123718] lm75: probe of 1-0048 failed with error -110
[ 10.246978] lm75 1-0049: supply vs not found, using dummy regulator
[ 11.419219] lm75: probe of 1-0049 failed with error -110


i2cdetect output on I2C1:

# i2cdetect -y 1
[controller timed out repeatedly]

U-Boot Observations (SDK 9.03 U-Boot):

=> i2c dev 1
Setting bus to 1
=> i2c probe
Timed out in wait_for_event: status=0000
Check if pads/pull-ups of bus are properly configured




  • This setup works fine with SDK 6.03.  with same hardware .

  • I2C1 is failing at both U-Boot and Linux Kernel level.

  • We suspect pinmux or pad configuration is missing/incomplete in the new SDK.

Questions:

  1. Has there been any change in I2C pad mux or pinmux configuration method between SDK 6.03 and 9.03 that we should account for?

  2. Are additional steps required to configure I2C1 (i2c@48072000) in U-Boot or Kernel in SDK 9.03?

  3. How can we ensure proper pad configuration (especially for I2C1_SCL and I2C1_SDA) in SDK 9.03?

    Any other steps to solve the issue

    This can be done using a simple diff, see below:

    Are additional steps required to configure I2C1 (i2c@48072000) in U-Boot or Kernel in SDK 9.03?

    No, not that I am aware of. 

    Shiv Rai said:
    How can we ensure proper pad configuration (especially for I2C1_SCL and I2C1_SDA) in SDK 9.03?

    Make sure you use the pin mux tool to change the settings. See the following app-note AM57xx Sitara™ IO Configuration Requirements

    Hi Jouse ,

    Thank you for your response. What could be the potential reasons for the I2C1 bus timeout? The hardware connections seem correct, and the pinmux configuration has also been verified.

    Shiv, 

    Have you double checked that there are no conflicts?

    What TI board is your custom board based off of?
