Yi 1080p Home IFUS is suddenly inaccessible

[cbroissa-github]

Hello,
I have two cam Yi 1080p Home IFUS, with HA integration, it worked perfectly.
But since a few days, I can't access the cam in HA, and http://ip-cam:8080/ is not reachable.
I can ping 'ip-cam'

My two others cam Yi Outdoor 1080p IFUS work in HA.

What could I do or check?
Thank you.

The httpd process is missing.
Check the free space
df
and dump the configuration
cat /tmp/sd/yi-hack/etc/system.conf

[cbroissa-github]

Sorry for the delay, I was in holidays :)

Here is the check for free space :
Filesystem 1024-blocks Used Available Use% Mounted on
/dev/root 1280 1280 0 100% /
devtmpfs 30400 1824 28576 6% /dev

And the dump

Thank you for your time with my problem.

Free space is ok.
About config, fix RTSP_AUDIO field adding a value:
RTSP_AUDIO=alaw

Finally, try to start httpd manually:
httpd -p 8080 -h /tmp/sd/yi-hack/www/ -c /tmp/httpd.conf

[cbroissa-github]

when I start httpd

-ash: httpd: not found

[roleoroleo]

You have to source the env:
. /tmp/sd/yi-hack/script/env.sh

[cbroissa-github]

ok done, but now I have this with the httpd command
Segmentation fault (core dumped)

The same message on my two cameras.

[roleoroleo]

Probably the binary is corrupted.
Maybe the sd card is not ok?
Try to create again the sd from scratch.

[cbroissa-github]

ok I have empty the card and put the release and it's now ok
