TS-7250-V3 FPGA I2C
The TS-7250-V3 supports the opencore I2C controller which is used for Mikrobus I2C.
The Mikrobus i2c port is /dev/i2c-4. Scan for devices with:
This will show what addresses ack on the bus. Linux i2c-tools (i2cdetect, i2cget, i2cset) can be used to interface with devices, or custom clients can be written.
