Hello I am not sure if problem is I2C adapter/bus or that demodulator I2C slave. If it is demod, then that workaround is correct place, but if it is not, then that is wrong and I2C adapter repeating logic should be used. I did some testing again... Loading mn88472 firmware 1000 times, it failed: 61 times RC polling disabled 68 times RC polling enabled 83 times RC polling enabled, but repeated failed message due to that patch
At least this confirms there is an issue.
I don't want apply that patch until I find some time myself to examine that problem - or someone else does some study to point out whats wrong. There is many things to test in order to get better understanding. regards Antti
I do have other hardware with with a mn88472 demod on it. A CX23102 bridge and a dibcom (Xbox one tuner). I think that running the same test on those hardware will tell where the issue is.
I know that Olli have worked on the Xbox one tuner, do you have any support patches that could help testing this? And did you observe any issues with the mn88472 demod when working on the Xbox one tuner ?
I am quite sure that I saw this on the mn88473 version of this hardware also. I just haven't had the time to test it. But I will postpone that until the tests on the other bridges are done.
