Firmware v3 changes - Githubissues

gonzoblue commented 7 years ago

I have the v3 firmware running on my camera and it has a few changes from v2. For reference, I started with the v0.0.1 sd card release. Here are the things I noticed or had to tweak to get it running on my v3 firmware vs the v2 firmware:

There is no iSC3S process, it appears to now be iCamera (two instances of this is running, and lsof shows them using /dev/video0 and /dev/video1)
You have to kill -9 (not just kill) to get both of the iCamera processes to stop. Once you stop them, the camera will restart within 30 seconds.
The restart seems to be tied to the watchdog module, which does not unload with rmmod (or else the 00-stop-cloud startup script would have taken care of it). I had to comment out where it gets loaded in /etc/init.d/rcS
There are two scripts to start up rtsp, 02- and 03- in the data folder. I have removed the 02 script as it seemed redundant.

Once I stopped the snx_wdt module from loading, then modified the 00- script to kill iCamera and used 03- to start up rtsp I have a stable stream coming from the camera running 3.0.3.53 firmware.

I understand and like the idea of making as few changes to the core system as possible, but I wasn't aware of any other way to stop the snx_wdt module from running without commenting it out on the actual device itself vs running a script post-boot. Maybe someone can figure a better way to take care of that.

Haven't had any time but will try V3 myself during the weekend hopefully. Thanks for the info! Did you try modprobe -rf to get rid of snx_wdt?

gonzoblue commented 7 years ago

Just tried, yup modprobe -rf snx_wdt works to unload the module. I've updated the 00 script on my card to do that instead. Thanks.

The rtsp server crashes every few hours for me, I wrote a little do:while script to check it and launch it again if it isn't running but I am not sure if this instability is new to v3 or just the way it is. For now it works well enough just getting restarted, but it might not work once I try to get a constant stream and record it with a DVR.

Has anyone noticed some of the cameras firmware updating to 3.0.3.53 while others remaining at 2.9.0.7?

phtp commented 7 years ago

I am running 2.8.3.5 and Mi Home prompted me couple days ago to update, but I ignored it. Now it's not longer prompting me and I noticed the Mi Home app updated instead.

Latest updates add V3 support, closing this issue.
