[fr0s7]

Sure, I'll gladly help.

Sure, I'll gladly help.

Sorry for the delay @fr0s7 ... please download this debug version:

curl --retry 3 "https://raw.githubusercontent.com/ViktorJp/RTRMON/develop/rtrmon-debug.sh" -o "/jffs/scripts/rtrmon.sh" && chmod 755 "/jffs/scripts/rtrmon.sh"

Then just run it like normal:

rtrmon -monitor

Wait until the script finishes running when it hits that error, then please copy all the output from your screen and dump it here below, or send me a file, or just PM it to me. I'd really appreciate it!

 

[fr0s7]

Done, attached is the output file.

 

[Viktor Jaep]

Done, attached is the output file.

Thank you! I think it has something to do with your CPU temps... could you please run this and see what you get back?

cat /sys/class/thermal/thermal_zone0/temp | cut -c -2

 

[fr0s7]

cat: can't open '/sys/class/thermal/thermal_zone0/temp': No such file or directory

Got to /sys/class/thermal directory but it's empty, I guess the temps are reported elsewhere?

cat: can't open '/sys/class/thermal/thermal_zone0/temp': No such file or directory

Got to /sys/class/thermal directory but it's empty, I guess the temps are reported elsewhere?

Could you please give this a try?

cat /proc/dmu/temperature

 

[fr0s7]

cat: can't open '/proc/dmu/temperature': No such file or directory

There's no dmu dir in /proc

 

[Viktor Jaep]

cat: can't open '/proc/dmu/temperature': No such file or directory

There's no dmu dir in /proc

Is there anything under /sys/class/thermal/thermal_zone1?

 

[dave14305]

cat: can't open '/proc/dmu/temperature': No such file or directory

There's no dmu dir in /proc

How about cat /sys/power/bpcm/cpu_temp

 

[fr0s7]

cat: can't open '/sys/class/thermal/thermal_zone1': No such file or directory

cat /sys/power/bpcm/cpu_temp
cpu_temp: 64.758 C

Nailed it.

Hi @fr0s7 ... What is the actual output when you run this command? Does it just show:

64.758

Or is there other info when you run that command? I need specifics please. Please paste all the output from your screen after running that command if you don't mind?

I think what he showed is exactly the one-line output.

Lol almost looks made-up!

OK @fr0s7 ... could you please give this patched version a shot, and see if this no longer produces errors, and gives you the correct temp readings?

curl --retry 3 "https://raw.githubusercontent.com/ViktorJp/RTRMON/develop/rtrmon.sh" -o "/jffs/scripts/rtrmon.sh" && chmod 755 "/jffs/scripts/rtrmon.sh"

 

[fr0s7]

Yes, this one works, checked different readings and all seems to match:
