Hi 6by9,
so, I have managed to obtain some logs. The first method by debugfs completely doesn't want to work (all the time everywhere "permission denied") so I have used the second method by placing "trace-event..." in cmdline file. OK, it works. So I have captured 4 files (and filtered out i2c-22 leaving i2c-10) :
1. traffic after power-up contains circa 25 "words"
2. the same after "reboot" command from console more than 350
3. command script for starting video streaming gives different traced results (close to the end of transmission) when sent just after first power- up boot than the same trace when observed after the second console reboot.
So there are small differences.
The first idea then is to make a software reboot after each power-up boot to achieve an image of proper parameters. Frankly speaking we do not need a picture on the monitor - this stream will be passed to USB for further transmission. But I am curious if these image parameters will also be different for the stream passed over USB for further transmission.
kind regards
Jacek
