Yep. No succesful tuning at the moment. There might also be an issue
with the reset signal and writing to GPIOCTR, as the module at the
moment loads succesfully only once.
As far as I can make out, the LNB power control is probably GPIO 16 and
17, not sure which is which, and how they work.
GPIO15 is wired to tuner #reset
New patch to test

Since the tuner at hand uses a Si2109 chip, VSTATUS 0x01 and 0x02 would
indicate that blind scanning is used. Blind scanning is a 2109/2110
specific function, and may not very usable since we always use initial
tuning files anyway. 2109/10 also supports the legacy scanning method
which is supported by Si2107708.
Is the use of blind scanning intentional?
Yes, of course, it's intentional. Why not?
User has freedom to make little errors in channels.conf file. Also the chip didn't support DVB-S2.
And last, has who si2107/08 ? My chip is si2109.
I agree, it's best to use the hardware features. I was worried that I
may be getting bad i2c data.
If I understand you correctly, you have a working Si2109 frontend driver?
Here's what I'm getting:
Added a few printouts to si21xx.c
u8 signal = si21_readreg(state, ANALOG_AGC_POWER_LEVEL_REG);
dprintk("%s : FE_READ_STATUS : AGC_POWER: 0x%02x\n", __func__,
signal);
si21_readregs(state, LOCK_STATUS_REG_1, regs_read, 0x02);
reg_read = 0;
for (i = 0; i < 7; ++i)
reg_read |= ((regs_read[0] >> i) & 0x01) << (6 - i);
lock = ((reg_read & 0x7f) | (regs_read[1] & 0x80));
dprintk("%s : FE_READ_STATUS : VSTATUS: 0x%02x\n", __func__, lock);
dprintk("%s : FE_READ_REGS : REGS[0]: 0x%02x\n", __func__,
regs_read[0]);
dprintk("%s : FE_READ_REGS : REGS[1]: 0x%02x\n", __func__,
regs_read[1]);

So, we have signal and sometimes we are getting carrier also.
What worries me most is the FE_READ_REGS : REGS[1]: 0x60
According to the datasheet this register 0x10 Lock status 2, is RCVL 0
0 0 0 0 BSDA BSDO so 0x60 would seem meaningless.
Same results using szap.

Signal but no lock.
Any ideas?
