Hi,
I'm trying to use the hard ip i2c with a fpga lattice iCE40 ultra plus. I have the breakout board.
when I symthetise the project I have this : I1202: Reading Architecture of device iCE40UP5K
Warning-1411: No clock is reaching the reference clock pin 'SBCLKI' of instance 'i2c_control.SB_I2C_INST_RT'. So, no gen clock will be inferred at output of this instance.
the clock signal is the clock system.
I'm using iCECube2.
I'm looking for a project example.
thanks
