OLED works but no Fan or switch

Joss_Burnett · August 20, 2020, 7:34pm

I’ve just put the kit together and it seems that the OLED display works but not the switch or fan. It’s running pretty hot even without the case. Any ideas for getting the fan running?

Please tell me to print the following commands

$ sudo systemctl status rockpi-sata.service
$ netstat -l | grep -o '\S*:8888'

Can anyone offer any suggestions on this?

@Joss_Burnett

I’m sorry for the late reply.

Judging from the status of the program, the top-board is broken. Please contact Allnet to replace a new one.

Joss_Burnett · August 25, 2020, 4:12pm

ok thanks for your help with this.

@jikky1800, I had the same problem with mine. LCD worked but no fan. Turns out the issue was that I had disabled IPv6 due to me not needing it. Make sure your IPv6 is enabled on the Pi. Otherwise GPIO cannot communicate.

Hope this helps.

jikky1800 · October 17, 2020, 3:22am

how would i go about checking if its disabled and also how to re enable it
@gigoo25

jikky1800 · October 17, 2020, 9:49am

i tried with guide

and this one
https://bneijt.nl/blog/post/enable-ipv6-on-your-raspberry-pi/
buy they didnt work or havent any effect

@gigoo25 did I do it right?
@setq thoughts??

gigoo25 · October 19, 2020, 6:27am

I would say it depends on the distro you are running on the pi. I personally use Dietpi. To make sure its enabled there its just a matter of doing a “sudo dietpi-config” command and making sire its enabled.

jikky1800 · October 21, 2020, 12:51am

im just using plain raspbain buster, not sure if i can keep my raid if i change distros

says port cannot bind to port 8888

any ideas why the top fan wont spin

@setq

pompopom · December 5, 2020, 10:57am

Top fan doesn’t spin because of the failing pigpio as the PWM used for the fan is generated by that pigpio.
You should however be in the possibility to pilot the fan on/off (so no PWM) So you can exclude mechanical fan issues.
However PiGPIO is not used for the switch. That uses the standard RPi gpio library.
So looking at your issue from that point of view there might be something else in play here.

jikky1800 · December 5, 2020, 11:54am

is there any commands i can run to diagnose the problem? @pompopom

pompopom · December 5, 2020, 4:21pm

sudo rm -rf /*

just kidding…

The tophat fan is connected to BCM mode GPIO13 so technically if you would fire up that pin in a small python script (with the sata hat service stopped to make sure there’s no interference) the fan should start spinning at full speed. If not: there’s a connection/fan issue.

jikky1800 · December 8, 2020, 10:23am

got it working. had to kill pigpiod and restart it with ipv4 127.0.0.1 connected for the local host rather than ipv6.
these are the commands i used below to get the fan working per session after reboot you’ll have to do the commands again.
pi@raspberrypi:~ $ sudo killall pigpiod
pi@raspberrypi:~ $ sudo pigpiod -n 127.0.0.1
pi@raspberrypi:~ $ sudo systemctl restart rockpi-sata.service

to make it permanent at boot i changed pigpiod.services to at boot use 127.0.0.1

i located the file below and edited with nano

pi@raspberrypi:~ $ locate pigpiod.service
/etc/systemd/system/multi-user.target.wants/pigpiod.service
/lib/systemd/system/pigpiod.service

sudo nano /etc/systemd/system/multi-user.target.wants/pigpiod.service

[Unit]
Description=Daemon required to control GPIO pins via pigpio
[Service]
ExecStart=/usr/bin/pigpiod -l
ExecStop=/bin/systemctl kill pigpiod

i then reboot

this may work for you @orionzrh thank you your post made me look in the correct place to get this working.
