sensor jxf23 not initialized in Xiaofang 1S

[mikolaj-kow]

Hi,

i have Xiaofang 1S, 64M model. It worked well with cfw. With this rootfs sensor can not be used.

Some debug and my configuration:

[root@DafangHacks:init.d]# echo 1 >/proc/jz/sinfo/info
[root@DafangHacks:init.d]# cat /proc/jz/sinfo/info
sensor not found

Is this a problem with memory allocation?

[fabicodes]

The problem seems to be with the driver, I've just got video working on my Xiaofang S1 with this rootfs. I'm going to create a pull request soon

[fabicodes]

Sorry, took me a while to continue on this. Could you please try my rootfs fork?

[mikolaj-kow]

Thanks, with your rootfs sensor is working.

However, the h264 stream 720p@15fps is freezing after 5~60 seconds with the default memory map mem=32M@0x0 ispmem=8M@0x2000000 rmem=24M@0x2800000.

Also audio is not available

Typo in detection script

[dsbaars]

I tried it as well, same problem. Freezes and reboots. Also tried with lowest resolution 640x360@10fps and CBR.
No improvement with memory map mem=41700K@0x0 ispmem=8M@0x28B9000 rmem=15644K@0x30B9000

[n1zzo]

Same here,
is there anything that I can try to fix this issue?

[n1zzo]

Fixed, the rtsp server was spinning to 98% CPU usage because of the audio error,
the solution is to use ALSA as a sound provider, which can be set by adding a -a to the /usr/controlscripts/rtsp-h264 file as in:

   if [ "$AUDIOFORMAT" != "OFF" ] ; then
        AUDIOPARAM="-a -E $AUDIOFORMAT:$AUDIOINBR:$AUDIOOUTBR"
        setconf -k h -v "$HWVOLUME" 2>/dev/null

@fabi280, please add it to the forked rootfs.

[fabicodes]

Thank you. I've added it but didn't check the fix yet :)

[dsbaars]

I tried it, but didn't solve it for me unfortunately :( I already disabled audio to try if that would make a difference, but that didn't as well.

[n1zzo]

Sorry to hear that @dsbaars, if you can open top and look at the CPU usage,
maybe there is some other process consuming too much resources.
Is there a way to check temperature sensors?
I have 5 minutes uptime now, I'll continue to investigate eventual freezes.

[n1zzo]

I've compared 1280x720 h264rstp vs 1920x1080,
they consume respectively 30% of CPU and 40% so this seems not to be a big issue.

[dsbaars]

I actually removed everything from autoboot, including lighttpd and using 640x360.
After manually starting using /usr/controlscripts/rtsp-h264, even without viewing the stream the load increases rapidly from 0.83 to 1.69 and then freezes.

These are the only processes running just before the freeze:

[n1zzo]

I see that you have the Mp3 encoding active, that should take some resources.
Can we see which resource makes the device freeze? If it is RAM depletion or thermal protection.
Or maybe it is a kernel panic, attaching a UART to the device could solve this doubt.

[n1zzo]

Could this be related?
samtap/fang-hacks#61
I got 7.30 hours of uptime without freezes during the night, so probably it's a thermal related issue.
Camera had IR led turned on and IR cut turned off.
Also on FHD the RTSP server gets killed by the kernel every ~2minutes, on 1280x720 it does not.
The audio is set on PCM:16000:44100.

[x86dev]

The at the moment compiled binary of v4l2rtspserver-master has hardcoded paths in it, which are not present (anymore) on the rootfs image See: #4.

For me symlinking the new locations to the old locations (where the current v4l2rtspserver-master expects the files) is fixing a lot a problems:

mkdir -p /system/sdcard/scripts
ln /usr/scripts/detectionTracking.sh /system/sdcard/scripts/detectionTracking.sh
ln /usr/scripts/detectionOff.sh /system/sdcard/scripts/detectionOff.sh
ln /usr/scripts/detectionOn.sh /system/sdcard/scripts/detectionOn.sh

Works as a temporary solution.

[x86dev]

... and one more for the night mode script:

ln /usr/scripts/nightmode.sh /system/sdcard/scripts/nightmode.sh

[quantum8]

I've tried the original rootfs, but couldn't get the image sensor working so I thought I'd give the forked rootfs a go. I still can't get it working though! I've cloned the forked rootfs into an ext3 formatted card, renamed the 64mb uEnv file, and entered my wifi details in WPA_Supplicant and it doesn't get past the step where it loads v4l2rtspserver-master. I get the page fault error:

DafangHacks login: [ 5.857088] do_page_fault() #2: sending SIGSEGV to v4l2rtspserver- for invalid read access from

Any ideas?
