LMK05028: LMK05028 I2C driver guidance

RanjithKumar T R

Part Number: LMK05028
Other Parts Discussed in Thread: USB2ANY

Hi team,

Will LMK05028 I2C transaction work properly if the device is connected both in TicsPro via USBANY and accessed via kernel I2C driver?

Should we remove the USBANY connection to avoid two I2C master race conditions?

Hello,

Yes, please remove the USBANY connection to avoid two I2C master race conditions. Either connect the USBANY OR the kernel I2C driver.

Regards,

Kia Rahbar

Hi,

Without any LMK programming or USBANY connection, we aren't able to see our LMK device on the i2c detect command.

We have attached the logs below,

Hello,

My best recommendation would be to program the LMK05028 solely using TICS Pro and a USB2ANY.

First, please go to the following link and install the TICS Pro software: https://www.ti.com/tool/TICSPRO-SW Then, construct a configuration for your device on TICS Pro.

Once you have the configuration created, you can connect the USB side of the USB2ANY to the computer with the TICS Pro software downloaded on it and you connect the pin side of the USB2ANY (specifically pins J4-1, J4-2, J4-5) to the SDA, SCL, and GND pins of the LMK05028 to communicate through I2C. Here is the link to the USB2ANY user guide so you can familiarize yourself with the device: https://www.ti.com/lit/ug/snau228/snau228.pdf?ts=1621012078298&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FUSB2ANY

Kia Rahbar
