The second generation controller has been fabricated in house and used with 240mA beam current at beginning of this year. The stability of amplitude and phase reaches 0.089% (RMS) and 0.093 degree (RMS) respectively. The recent progress on digital LLRF for FEL will be also reported such as the development activities and test results on the local oscillation generation board and down converter board.
