I2C Communication with CMPS on Zybo



Hi, I have a problem with my i2c communication with digilent pmod CMPS. I've routed i2c-0  via EMIO to the Pmod. Pullups are enable. I can send only one frame with initialization data and then I can't send anything. I checked the transmission using logic analyzer, and I have no idea why the i2c port is blocked. To send another frame i have to restart system. I would be grateful for any help. I2c is rather OK because gyroscope works fine.
