Getting I2C working

Hello, I have been trying to get I2C working on my Jetson TX2. I have an ESC that communicates with I2C and has an address of 0x2A. I have attempted to plug the ESC into both I2C-2 and I2C-3 clock and data pins on the tegra and running i2cdetect on all available buses, but it still can’t detect the address of the ESC. Do I need to enable the I2C pins or something?

Generally no such request of enabling I2C pins. Can you please show the details connections or this part of schematic? Do you connect the GND of ESC to TX2?
