stb0899 signal strength value in dvb-s2

Hi everyone,

Using a KNC-1 DVB-S2 board I noticed stb0899_read_signal_strength() in stb0899_drv.c always return the same value (1450) in dvb-s2 whatever the signal power is.

It seems STB0899_READ_S2REG(STB0899_DEMOD, IF_AGC_GAIN) macro always returns zero.

Any idea of what is causing this ?
