Hi. Recently i upgraded to Armbian_5.65_Orangepilite_Debian_stretch_next_4.14.78 and i have two problems. I can not read the thermal zones properly with neither of those:

cat /sys/class/thermal/thermal_zone0/temp
cat /sys/devices/virtual/thermal/thermal_zone0/temp
cat /etc/armbianmonitor/datasources/soctemp

because i have results like "30371". But when the system starts the correct temperature is displayed:

Welcome to ARMBIAN 5.73 stable Debian GNU/Linux 9 (stretch) 4.19.20-sunxi
System load:   0.07 0.15 0.10   Up time:       10 min

CPU temp:      33°C
Usage of /:    10% of 15G

and with armbianmonitor too:

My second problem is that my DS18B20 sonda does not work anymore. In /etc/modules-load.d/modules.conf i have:

w1-sunxi
w1-gpio
w1-therm

but there is nothing in /sys/bus/w1/devices/
 

is there any changes in this new version? I check the forum but i does not found anything. Any iddeas?

 

Thanks in advance.

You should not place any W1 driver in /etc/modules-load.d/modules.conf ...

You should rely on DT overlays : https://docs.armbian.com/User-Guide_Allwinner_overlays/

... and more specially to H3 W1-Bus overlay parameters : https://github.com/armbian/sunxi-DT-overlays/blob/master/sun8i-h3/README.sun8i-h3-overlays#L231,L250

Yes. Thank you martinayotte. If sombody needs that, i just have to add this lines to '/boot/armbianEnv.txt'

overlays=w1-gpio
param_w1_pin=PA20
param_w1_pin_int_pullup=1

and works like a charm! Thank you very much.

And, what about the strange readings in thermal_zones. My cpu give me 22.6ºC with armbianmonitor, but reading directly in any of the thermal zones with cat i have readings like '40898'.

 

What has changed from previous versions?

 

Than you in advance.

wow. I just realized that the CPU temperature in armbianmonitor is the same that the one i have reading the DS18B20 sonda ....

 

What is going on??

 

DS18B20 can't work for a long time

what is the MIN_SPEED in /etc/default/cpufrequtils ? If it is too low, W1 may get into trouble, I´m usually set the MIN_SPEED to 480000 ...

My OrangePi One and wires. Is it PA20 ?

As said in the other thread : In /boot/armbianEnv.txt, along with adding w1-gpio to overlays, did you provided W1 parameters, param_w1_pin and param_w1_pin_int_pullup ?

Maybe you need a resistor in your circuit?

 

 

mantouboji,

• you can give this command: cat /sys/kernel/debug/pinctrl/1c20800.pinctrl/pinmux-pins, and cat /sys/kernel/debug/pinctrl/pinctrl-maps
• you should have the sensor connected to pin 37 and the PA20 in your armbianEnv.txt: instead there seems to be PA10.
• can you put a photo of your sensor and how it is connected?

ps: the dupont connector in the photo at pin 37 does not appear to be securely attached

I chang to use PIN 4 to get 5V and PIN6 to get GND, it works. Thx .

 

But only works for a short time, now :

I replace the ds18b20 detector head with a new one , and all works well . 

 

Thanks all.

 

Now I use another OrangePi One board to do some testing.

 

It runs an old version of Armbian

I connect 3 18B20 heads to PA20. 

It can't  find any of them.

 

so I upgrade to the latest version

Welcome to ARMBIAN 5.73 stable Ubuntu 18.04.2 LTS 4.19.20-sunxi

 

Now it works.

 

So there must be some fix after 4.14.81 .

 

My configuration files are:

/boot/armbianEnv.txt

verbosity=1
logo=disabled
console=both
disp_mode=1920x1080p60

param_w1_pin=PA20
param_pps_pin=PA7
usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u

 

the /etc/default/cpufrequtils file is the default one.

 

# WARNING: this file will be replaced on board support package (linux-root-...) upgrade
ENABLE=true
MIN_SPEED=408000
MAX_SPEED=1200000

 The pull-up resistor must be 4.7K.
