# v4l2-dbg -d /dev/video0 -c host1 --list-registers=min=0x800,max=0x9ff Keep in mind that some of these registers aren't settable and only read out the state of various hardware blocks and functions. Dumping the state of the microcontroller memory could also be done, but I'd have to modify the driver to do it. cx18-av-firmware.c:cx18_av_verifyfw() has code that's really close to doing that.
.. Thanks. I'll have a go at that some night. Meanwhile, tonight, audio failed. The syslog shows the usual "fallback" messages, but the audio consisted of very loud static, the kind of noise one gets when the sample bits are all reversed. While it was failing, I tried retuning, stopping/starting the recording, etc.. nothing mattered. It wanted a reload of the cx18 driver to cure it.
If needed, once we're in a forced mode, we could stop the microcontroller, reload all of the microcontroller firmware, and restart it. Kind of heavy handed, but it may work.
.. Perhaps that's what is needed here. Cheers -- Mark Lord Real-Time Remedies Inc. mlord@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
