TPS65400EVM-678: TPS65400EVM-678

Hello,

I am using USBtoany to communicate to TI board (Voltage Regulator) TPS65400EVM-678. I am using USBtoany software with version (API v2.8.2.0) as mentioned below in this forum, the slave address is 0x6A by checking the manual 22k in the I2C address selection. I checked the RST_N is high (3.14V), VDDA is 6.14V, RST_N is 3.13V. So this concludes that my chip is powered on but anyhow I am not able to send any instruction to the chip.

However, I am able to see the Data and clock activity. But the issue is upon reading/writing to any address, it's returning NAK (Address not acknowledged).

Waiting for your response!

Thanks in advance
