i5Js

How can I figure out which is the pin of the fan on my nanopc t4? Because when I run the script I get the following: Traceback (most recent call last): File "test_fan.py", line 36, in <module> fan_rpm() File "test_fan.py", line 8, in fan_rpm with GPIO(70) as rpm_gpio: File "/home/i5Js/.local/lib/python2.7/site-packages/periphery/gpio.py", line 32, in new return SysfsGPIO.__new__(cls, *args) TypeError: __new__() takes exactly 3 arguments (2 given) Thanks.

Ok, it’s working perfect.

It was fixed flashing with FriendlyElec core image and then armbian... I’m going to test now the fan service.

It's strange because this behaviour is after booted from MicroSD and transfer the system with nand-sata util...

Buster server with kernel 4.4 I’ll reflash the sd card again and give it a second chance.

Ufff this is insane, now says: mount: no such device Failed to mount /dev/mmcblk1p2 as root file system. (This I gues is still EMMC) (initramfs)

Hi Thanks for your answer, do you know how many secs? Because it’s imposible!! Thanks.

I'm unable now to boot from MicroSD and flash other Arabian version on the EMMC memory... It's quite desperate because always boot from EMMC

Ok, many thanks, I'll and keep you updated.
